Here's the uncomfortable truth about retirement planning: most people are not on track.

The Federal Reserve's 2022 Survey of Consumer Finances found median retirement savings of $87,000 for Americans nearing retirement age — a number that, at a 4% withdrawal rate, generates about $3,480 per year in portfolio income. Combined with Social Security, many people will manage. But "manage" and "retire comfortably with financial independence" are very different things.

The gap between where most people are and where they need to be is, in part, a knowledge gap. Millions of people have no concrete idea whether they're on track. They contribute something to their 401(k) and hope for the best, with no model for what "enough" actually looks like for their specific circumstances.

Retirement planning tools close that gap. The best ones take your actual numbers — current savings, savings rate, expected retirement age, projected expenses — and run them through a model that tells you probability of success, not just a vague "good" or "not good."

In 2026, several strong tools exist for this. Here's how they compare — and which one wins for anyone who wants a genuinely complete retirement picture.

What a Good Retirement Calculator Actually Does

Before getting into specific tools, it's worth being clear about what separates a genuinely useful retirement calculator from the cheap ones littering the internet.

Surface-level calculators ask you for a savings rate and assumed return, then show you a projected balance at age 65. Useful for a very rough estimate. Not useful for actual planning.

Serious retirement planners do several things that surface-level tools don't:

• Monte Carlo simulation: Instead of assuming a fixed return every year, Monte Carlo runs thousands of scenarios using historical market volatility. Some years the market is up 30%. Some years it's down 40%. The simulation models this randomness and tells you what percentage of scenarios end with you still having money at age 90. This "probability of success" figure is far more honest than a straight-line projection.

• Inflation adjustment: Your $80,000 annual spending in 2026 will need to be $120,000+ by 2046 to buy the same things. Tools that don't inflation-adjust are giving you fantasy projections.

• Social Security integration: Ignoring Social Security understates your retirement income. The best tools let you input your expected benefit and factor it into the calculation.

• Spending flexibility: Many retirees spend more early in retirement (travel, activity) and less later. Better tools let you model variable spending patterns rather than assuming flat expenses for 30 years.

• Full portfolio integration: The most powerful retirement tools connect to your actual accounts — so they're modeling your real portfolio, not hypothetical numbers you typed in.

The Best Free Retirement Planning Tools in 2026

1. Empower Retirement Planner — Best Overall (Free)

Cost: Free Monte Carlo: ✅ Yes Connects to real accounts: ✅ Yes Social Security modeling: ✅ Yes

Empower's Retirement Planner is the most powerful free retirement planning tool available right now, and it's not particularly close.

The reason it wins: it doesn't ask you to type in hypothetical numbers. It connects to your actual financial accounts — every bank account, brokerage account, 401(k), IRA, and credit card — and models your retirement using your real portfolio.

Here's what the tool does with that data:

It calculates your current net worth in real time. Not an estimate based on what you typed — your actual portfolio value as of today.

It runs Monte Carlo simulations on your actual holdings. Based on your current asset allocation (not a generic assumption), Empower runs thousands of market scenarios and tells you what percentage of them result in you hitting your retirement goals. If you're 70% in equities and 30% in bonds, it uses that. If you're 90% in a single stock, it catches that too.

It models multiple income streams. Plug in your expected Social Security benefit, any pensions, expected rental income, part-time work in retirement — Empower integrates all of it into the probability calculation.

It lets you test scenarios. What if I retire at 60 instead of 65? What if I increase my savings rate by 2%? What if I adjust my asset allocation? Every change recalculates in real time, so you can see the concrete impact of each decision.

The Investment Fee Analyzer is a bonus. Before you can retire comfortably, you need to stop losing money to fees. Empower's fee analyzer scans your fund holdings and projects the dollar cost of your expense ratios over your investment timeline. Many people discover they're losing $30,000–$80,000 over 20 years in fees they didn't know they were paying.

For a completely free tool, the sophistication here is remarkable. This is the kind of analysis that financial advisors charge hundreds of dollars per hour to provide — and Empower gives it away because they hope you'll eventually use their paid wealth management service (which you don't have to).

2. Fidelity Retirement Score — Good for Fidelity Customers

Cost: Free Monte Carlo: ✅ Yes (within Fidelity accounts) Connects to real accounts: ✅ For Fidelity accounts; limited for external Social Security modeling: ✅ Yes

Fidelity's myPlan tool and Retirement Score calculator are excellent — if your money is at Fidelity. The platform analyzes your Fidelity accounts deeply, runs scenarios, and gives you a color-coded "retirement score" that estimates whether your current trajectory hits your income goal.

The weakness: if you have accounts at Schwab, Vanguard, a company 401(k), and an old 401(k) from a previous employer, Fidelity only sees the part that lives with them. You can manually enter external account values, but you lose the analytical depth that comes from connected accounts.

For someone with all or most of their retirement assets at Fidelity, this is a strong tool. For anyone with a fragmented picture across multiple institutions — which is most people — it gives you an incomplete model.

Best for: Fidelity-primary users who want their retirement analysis to live inside their brokerage dashboard.

3. Vanguard Retirement Nest Egg Calculator — Simple and Honest

Cost: Free Monte Carlo: ✅ Yes Connects to real accounts: ❌ No — manual input only Social Security modeling: ❌ Not integrated

Vanguard's retirement calculator is clean, honest, and built around Monte Carlo simulation — which immediately puts it above most of the junk calculators online. You input your current balance, expected annual spending in retirement, and asset allocation, and it tells you the probability of that nest egg lasting 25 or 30 years.

What it does well: the Monte Carlo math is sound, the interface is clear, and Vanguard isn't trying to sell you anything in the process.

What it lacks: there's no Social Security integration, no multi-account connection, no savings rate projections, and no "what if" scenario modeling. It's a single-question tool: "Given what I have and what I plan to spend, will it last?" It doesn't help you build toward retirement — it only evaluates a finished portfolio snapshot.

Best for: A quick sanity check on whether your current nest egg is large enough to sustain your planned spending. Not a substitute for full retirement planning.

4. NewRetirement — Most Comprehensive (Paid for Full Access)

Cost: Free tier available; full access $120/year (PlannerPlus)

NewRetirement is the most detailed retirement planning platform available to individual consumers. The full version allows you to model Roth conversion strategies, Social Security optimization (claiming age comparison), multiple spending phases, long-term care scenarios, tax-efficient withdrawal sequencing, and more variables than most people will ever need.

For someone who wants to get genuinely granular — down to modeling specific tax brackets in retirement, optimizing Roth vs. traditional withdrawal order, or planning for a variable annuity alongside a brokerage account — NewRetirement's PlannerPlus is worth the $120/year.

The free tier is meaningful but limited. You can build a basic retirement plan and get a probability score, but the advanced scenarios and optimization tools are locked behind the subscription.

Best for: People within 10–15 years of retirement who want to optimize every variable and are willing to pay for analytical depth.

Where Empower wins: For most people — especially those in the accumulation phase, still decades from retirement — Empower's free tools are more than sufficient, and the real-account integration makes the projections more accurate than anything you'd manually enter into NewRetirement anyway.

How to Read Your Retirement Probability Score

Most of these tools will give you a probability of success — the percentage of Monte Carlo scenarios in which your portfolio doesn't run out of money before your planning horizon (typically age 90 or 95).

Here's a rough interpretation guide:

90%+ probability: You're in excellent shape. Your current trajectory is very likely to fund your retirement. You can afford to take more risk with your allocation, retire earlier, or spend more in retirement — or some combination.

75–90% probability: Good, but not bulletproof. A severe market downturn in the early years of your retirement (sequence-of-returns risk) could strain your plan. Consider building a 1–2 year cash buffer and maintaining some spending flexibility.

60–75% probability: Reasonable but fragile. A meaningful improvement in one area — savings rate, timeline, asset allocation, fee reduction — could push you into the comfortable range. Run scenarios to see which lever has the biggest impact.

Below 60% probability: You need to make real changes. The good news: running through these tools when you still have time to change behavior is exactly what they're designed for. The math is reversible. You're not on track — yet.

The Step Most People Skip: Checking Fees First

Before you can model a realistic retirement, you need to know how much of your returns are being eaten by fees.

A 401(k) heavy in actively managed funds might be charging 0.80–1.20% per year in expense ratios — which sounds small but compounds dramatically. On a $200,000 balance, the difference between 0.10% (index fund) and 0.90% (active fund) is roughly $80,000 over 20 years in lost compound growth.

Empower's free Fee Analyzer catches this automatically. It's one of the first things to run after connecting your accounts.

If you want to evaluate the stocks themselves — whether your equity holdings are priced at a fair value — use our free Intrinsic Value Calculator at valueofstock.com/calculator to run a quick Graham Number analysis on any individual holding.

The Retirement Number Isn't Arbitrary — Here's the Math

People often say "I want $1 million for retirement" without knowing if that's too much, too little, or exactly right for their situation.

Here's the simple framework:

Annual spending in retirement × 25 = approximate portfolio target

This comes from the 4% rule — if you withdraw 4% of your initial portfolio annually (adjusted for inflation), historical data suggests high probability of lasting 30 years.

Some examples:

• $40,000/year retirement spending → need ~$1,000,000
• $60,000/year retirement spending → need ~$1,500,000
• $80,000/year retirement spending → need ~$2,000,000
• $100,000/year retirement spending → need ~$2,500,000

These figures assume Social Security and any pension cover part of your spending. If you expect $20,000/year in Social Security, your portfolio only needs to cover the gap.

This is exactly the kind of calculation Empower's Retirement Planner automates — and then goes beyond, modeling the actual probability rather than just the target number.

Build Your Investment Toolkit

Retirement planning doesn't happen in a vacuum. If you hold individual stocks in your retirement or brokerage accounts, make sure you're holding them at a reasonable price. The StockWise6 Toolkit on Gumroad includes a Graham Number screener, dividend income projector, and portfolio review checklist — tools designed for investors who want to understand what they own, not just that they own it.

Pair it with Empower's free retirement planner for a complete picture: are your assets worth what you think, and will they be enough when you need them?

The Bottom Line

The single biggest retirement planning mistake isn't picking the wrong stock or missing a contribution window. It's not knowing where you stand — and therefore not knowing that you need to change anything.

Every tool in this guide helps close that gap. But for most people — especially those still in the accumulation phase with accounts spread across multiple institutions — Empower is the strongest free retirement planning tool in 2026. Real account connection, Monte Carlo simulation, fee analysis, and Social Security modeling, all for free.

The math only works in your favor if you run it in time to act on what it tells you.
