2026 Retirement Calculator Comparison Table

We evaluated seven leading retirement calculators across five core dimensions. Here's how they stack up side by side.

1. Empower Retirement Planner — Best Overall Free Retirement Calculator

Best for: Anyone who wants free Monte Carlo analysis linked to their actual investment accounts.

Empower Personal Dashboard is the best free retirement planning tool in 2026 with Monte Carlo simulations and automatic account aggregation. That combination is what separates it from every other free option on this list. Most free calculators ask you to manually type in balances. Empower pulls them live.

Within your Empower dashboard, you'll gain access to the Retirement Planner, a retirement calculator that will allow you to run a Monte Carlo simulation based on your current portfolio and other major financial events that you input — like a home purchase, when you plan to take Social Security, and more. That's an enormous amount of functionality at zero cost.

The tool accounts for large financial expenditures along the way, not just retirement. Most calculators assume your savings are all for retirement and ignore major purchases like college educations or home purchases. Empower's Retirement Planner allows you to input these events, when you think they'll occur, and how much they'll cost, then recalculates to see how those expenditures affect retirement goals.

The Retirement Planner allows users to model both income events (such as savings, sale of real estate, Social Security, and pensions) and spending goals (such as retirement spending, travel, and education). Users can also set up multiple scenarios to compare, such as retiring at different ages. Empower then runs the data through a Monte Carlo simulation and reports the likelihood of the plan's success.

WG Verdict: If you're willing to link your accounts, Empower is the most powerful free retirement calculator available in 2026. Use it as your primary planning hub and supplement with Boldin if you need deep tax modeling.

2. Boldin PlannerPlus — Best for Deep Tax Modeling and Roth Conversions

Best for: Pre-retirees aged 45–65 who want CFP-level planning software without paying for a CFP.

Formerly known as NewRetirement, Boldin goes far beyond a basic retirement calculator by allowing you to model detailed financial scenarios based on your actual life circumstances. The rebranding happened a few years ago — the product is fully active and thriving as of 2026.

Boldin offers deeper planning features: Social Security optimization, Roth conversion modeling, Medicare cost projections, and detailed tax-bracket management. Those four features are exactly what separate a good retirement plan from a great one. Most free calculators skip all four.

Boldin gives you powerful retirement planning tools, and PlannerPlus takes it further with advanced tax optimization, Monte Carlo simulations, and unlimited AI guidance. Over 250,000 people are planning with Boldin.

On pricing, the tiers are clearly structured. The free version includes basic planning, "what if" scenarios, Monte Carlo analysis, Social Security Explorer, and Roth Conversion Explorer. PlannerPlus at $144 per year unlocks the full planner software, the ability to compare scenarios, and access to live Q&A sessions. There is also a Boldin Advisors tier at $2,800 per year, which provides access to CFP professionals.

The Retirement Chance of Success chart forms the centerpiece of your plan. Based on your inputs, it forecasts your savings balances each year in retirement. It also forecasts your overall chance of success, where success is defined as not outliving your savings.

WG Verdict: PlannerPlus rivals the tools used by Certified Financial Planner professionals, but is accessible to DIY investors at a fraction of the cost. At $144/year, it's the strongest value in paid retirement planning software.

3. T. Rowe Price Retirement Income Calculator — Best Standalone Free Tool

Best for: People who want a rigorous, no-account-linking-required retirement projection they can complete in under 10 minutes.

With a near-perfect score on usability, a sophisticated approach to analysis, a deep level of customization, and a free price tag, the T. Rowe Price Retirement Income Calculator was the top pick for the best overall retirement planning calculator in independent testing. The questions it asks are detailed enough to give you a clear idea of whether you're on track to retire, but high-level enough to get your answer in under five minutes.

The tool's Monte Carlo engine is particularly solid. The calculator uses Monte Carlo analysis to generate 1,000 hypothetical scenarios based on inputs such as performance of various asset classes, saving and spending assumptions, a client's time horizon, life expectancy, income, and expenses, and other variables. The Monte Carlo analysis provides ranges of potential future outcomes based on a probability model, running the user's scenario 1,000 times.

The T. Rowe Price Retirement Income Calculator provides an estimated probability of success in reaching your retirement goal (i.e., not running out of money in retirement) and whether you are in the retirement Confidence Zone for achieving your retirement goal. This metric is referred to as your Confidence Score, which is shown as a percentage in the tool.

T. Rowe Price also offers a dedicated Social Security Optimizer that can help you estimate the optimal age to start collecting benefits. That's a key add-on that makes the suite genuinely useful for pre-retirees doing final-stretch planning.

WG Verdict: The T. Rowe Price Retirement Income Calculator is the best free option if you'd rather not connect financial accounts to a third-party app. The 1,000-scenario Monte Carlo engine gives you genuinely institutional-grade output at no cost.

4. Fidelity Planning & Guidance Center — Best for Fidelity Account Holders

Best for: Existing Fidelity customers who want a seamless, all-in-one retirement readiness check tied directly to their accounts.

The Planning & Guidance Center helps make it easy to get a holistic view of your financial plan from one place. With this tool, you can see how prepared you may be for retirement, review and evaluate different investment strategies, and get a report with clear next steps to consider.

Fidelity's free Retirement Score provides an instant readiness assessment — this is the fastest on-ramp of any tool on this list. If you have five minutes and want to know immediately whether you're on track, the Retirement Score is where to start.

The Fidelity suite goes well beyond a single score. You can understand the impact various taxable and tax-free withdrawal strategies could have on your current-year taxes, and strategize when to claim Social Security by estimating monthly and lifetime benefits at different ages. You can also evaluate the impact a Roth conversion could have on your financial outlook.

Fidelity's retirement planning tool shows how much leeway you have and what moves the needle. It isn't designed to give year-by-year tactical guidance. That's an honest limitation worth knowing upfront. Think of it as a directional dashboard, not a granular tactical planner.

WG Verdict: If your primary retirement accounts live at Fidelity, this tool is a no-brainer first stop. For users at other brokerages, the T. Rowe Price or Empower tools will deliver more value with less friction.

5. Vanguard Retirement Income Calculator — Best for Simple, Quick Projections

Best for: Beginners or anyone who wants a no-frills snapshot using the 4% rule without setting up an account.

Vanguard's calculator is transparent about its methodology — and that transparency is refreshing. To calculate your retirement income, Vanguard first determines how much you'll have saved by the time you reach retirement (your "nest egg"). Then it uses the "4% rule" — assuming you can afford to spend approximately 4% of your initial nest egg each year in retirement and be reasonably confident that you won't outlive your savings. The result is adjusted for inflation at 3% annually.

The tool also integrates Social Security. This includes the estimated Social Security retirement income you'll receive beginning at age 62 or later. Pension income is factored in as well, with Vanguard assuming your pension will increase until retirement to keep pace with inflation.

The limitation is that Vanguard's tool does not run Monte Carlo simulations. Most free retirement calculators use a fixed return and ignore taxes entirely — two factors that can swing your retirement estimate by $200,000 or more. Vanguard's calculator falls into this category. For a quick directional check, it's fine. For serious planning, you need something deeper.

Context matters here too. The average 401(k) balance across nearly 5 million accounts Vanguard administered at year-end 2025 was $167,970 — a record high, up 13% from the year before. The median balance, however, tells a different story at $44,115 — the balance belonging to the worker planted exactly in the middle of the distribution, with half of Americans above and half below. A retirement calculator is what helps you understand which side of that line you're on and what it will take to close the gap.

WG Verdict: Vanguard's calculator is a solid 15-minute reality check. Don't use it as your only planning tool, but do use it as a quick gut-check before diving into Empower or Boldin for the full picture.

6. ProjectionLab — Best Retirement Calculator for FIRE Planners

Best for: Financial Independence, Retire Early (FIRE) enthusiasts who want historical backtesting, multi-scenario modeling, and granular control over every assumption.

ProjectionLab is the retirement planner that the FIRE community built for itself. It shows. The level of customization is a step above what mainstream brokerage calculators offer, and it's popular on Reddit's r/financialindependence community for exactly that reason.

ProjectionLab takes the prize for total life planning. It integrates tax planning, life events, and has an easy-to-use interface.

You enter assets, income sources, and assumptions manually, then run scenarios using Monte Carlo simulation or historical return sequences. The Roth Optimizer, a Premium feature, coordinates conversions, drawdown order, and gain harvesting around a tax target. That's a level of sophistication that would typically require a high-end financial planning software subscription.

The 250+ input model with Social Security optimization, Roth conversion explorer, and tax projection features addresses exactly the decisions that have the biggest impact on retirement income in the final phase of working life.

WG Verdict: ProjectionLab is the power-user choice for anyone pursuing early retirement or who simply wants maximum control over every assumption in their plan. If you've already outgrown Empower and Boldin's free tier, this is your next step.

7. Social Security Administration Retirement Estimator — Best for Benefit Verification

Best for: Verifying your actual projected Social Security benefit before plugging that number into any other retirement calculator.

No retirement calculator can model your Social Security benefit as accurately as the Social Security Administration itself. The SSA's online estimator pulls from your actual earnings record — not an assumption based on your current salary — which means the output is anchored to real historical data.

The estimator lets you model claiming ages from 62 through 70. Delaying Social Security from age 62 to 70 can increase your monthly benefit by up to 76%, making the timing decision one of the most consequential in retirement planning. Use the SSA tool to get your actual baseline numbers, then import those figures into Empower, Boldin, or T. Rowe Price for full-plan modeling.

This tool works best as a data-gathering step rather than a standalone planning solution. It tells you your benefit; it doesn't tell you whether you have enough saved, how long your money will last, or what your taxes will look like in retirement. Pair it with a more comprehensive calculator.

WG Verdict: Always start here to get your real Social Security number before running projections anywhere else. A wrong Social Security assumption can throw off your entire retirement plan by tens of thousands of dollars.

How to Choose the Right Retirement Calculator: A Step-by-Step Guide

The best retirement calculator is the one matched to your specific situation and life stage. Here's a systematic way to decide.

1. Start with your 2026 contribution limits. Before modeling anything, make sure you know what you're allowed to save. The 401(k) contribution limit for 2026 is $24,500 for employee salary deferrals, and $72,000 for the combined employee and employer contributions. For 2026, the IRA contribution limits are $7,500 for those under age 50 and $8,600 for those age 50 or older. Any good calculator should already have these baked in.
2. Decide whether you'll link accounts. If you're comfortable connecting your brokerage, 401(k), and bank accounts to a third-party app, use Empower — it gives you the most accurate real-time projections. If you prefer privacy, T. Rowe Price's standalone tool is the best non-linking option.
3. Check whether you need Monte Carlo. A static projection — one number, one assumed rate of return, one expected inflation rate — is almost guaranteed to be wrong over a retirement spanning several decades. The best retirement calculators in 2026 offer dynamic, multi-variable modeling that lets you adjust assumptions, stress-test scenarios, and see a realistic range of outcomes rather than a single optimistic guess. If your tool doesn't run Monte Carlo, upgrade.
4. Assess your tax complexity. If you have a Roth and a traditional IRA, are considering Roth conversions, or have multiple income streams in retirement, you need a tax-aware tool. Boldin PlannerPlus handles this best. Fidelity's suite and T. Rowe Price also have Roth conversion estimators built in.
5. Know your Social Security number first. Pull your actual projected benefit from the SSA estimator before entering any Social Security figure into another calculator. This single step will make every subsequent projection more accurate.
6. Match the tool to your FIRE timeline. Targeting standard retirement at 65? Empower and T. Rowe Price are built for you. Targeting FIRE at 50? ProjectionLab's historical backtesting and Boldin's tax modeling are better suited to the longer, more complex drawdown period.
7. Revisit your plan annually. The best retirement calculators in 2026 model compound growth on savings, account for inflation, include Social Security income estimates, apply current 401(k) and IRA contribution limits, and project whether your nest egg will last through retirement. As IRS limits, market conditions, and your personal situation change, your projections need to be refreshed. Set a calendar reminder every January.

Why Most Free Retirement Calculators Give You Dangerous Answers

Not all retirement calculators are honest with you. Here are the most common failure modes to watch for.

They Ignore Taxes

Most free retirement calculators use a fixed 7% return and ignore taxes entirely — two factors that can swing your retirement estimate by $200,000 or more. A calculator that doesn't account for required minimum distributions (RMDs), ordinary income tax on traditional 401(k) withdrawals, and capital gains tax on taxable accounts will always give you an overly optimistic picture.

They Use a Single Return Assumption

A single projection assumes steady returns like 7% every year. In reality, early bad markets can cut your savings short even if averages look fine later. When a Monte Carlo tool runs 1,000 market paths, you learn whether your plan succeeds in 720 cases or only 480. The difference tells you where to adjust savings or spending before you retire.

They Don't Model Sequence-of-Returns Risk

Retiring into a bear market — even with the same average long-term returns — can devastate a retirement portfolio. A 20% drop in year one of retirement has a vastly different impact than the same drop in year fifteen. Only Monte Carlo-based tools capture this risk properly.

They Skip Healthcare

Healthcare is often the largest single expense in retirement, and it's the one most calculators quietly ignore. Look for tools that include Medicare premium projections and, ideally, IRMAA (Income-Related Monthly Adjustment Amounts) modeling for higher-income retirees.

The 2026 Retirement Savings Landscape: Why These Numbers Matter

Running a retirement calculator isn't just a planning exercise. For many Americans, it's a wake-up call.

The median 401(k) balance — the balance belonging to the worker planted exactly in the middle of the distribution — is $44,115. Run it through a standard 4% annual withdrawal rate and you get $1,765 a year, or $147 a month. That's not a retirement. That's a supplement.

A common guideline is to save 25 times your expected annual retirement expenses — the 4% rule. For example, if you expect to spend $60,000 per year in retirement, you'd need approximately $1.5 million saved. Your actual target depends on your retirement age, expected Social Security benefits, healthcare costs, inflation assumptions, and investment returns.

The gap between where most Americans are and where they need to be is significant. A retirement calculator doesn't close that gap, but it does show you precisely how wide it is and what levers — savings rate, retirement age, spending level, Social Security timing — can narrow it fastest.

On the positive side, according to a June 2026 Investment Company Institute survey, nearly half of all Americans with a 401(k) say they probably wouldn't be saving for retirement at all without one. Automatic enrollment and auto-escalation features are genuinely changing savings behavior. The tools exist to help you maximize that momentum.

Also worth noting: according to Vanguard, the U.S. stock market is expected to deliver an annualized return of between 4% and 5% over the next five to ten years. That's uncomfortably close to the 4% withdrawal rate many retirees depend on to meet living expenses. A conservative return assumption in your retirement calculator — not the traditional 7% — may be the more prudent choice for 2026 planning.
