Retirement Calculator
Project your 401(k) at retirement as a conservative-to-optimistic range with real tiered employer match and inflation-adjusted values. No signup.
A realistic range, not one false-precision number
Over 35 years, here's what your balance could look like across a conservative and an optimistic return assumption — with the today's-dollars value shown alongside so inflation doesn't distort the headline.
$1,093,800
nominal balance at retirement
$460,896 in today's dollars

That's $3,000 of free money each year — over 35 years that alone is roughly $105,000 of contributions before any market growth.
Traditional vs. Roth 401(k) — the honest one-liner
This is an informational explainer, not a second calculation mode. Both options grow tax-free while invested — the difference is when the tax hits.
Traditional 401(k)
Contributions come out of your paycheck before federal income tax — you get the tax break today, which lowers your taxable income now. In retirement, every dollar you withdraw is taxed as ordinary income at whatever bracket you're in then.
Often better if you expect to be in a lower tax bracket in retirement than you are today.
Roth 401(k)
Contributions are made with after-tax dollars — no tax break today. In retirement, qualified withdrawals (both contributions and all the market growth) come out completely tax-free.
Often better if you expect to be in the same or higher tax bracket in retirement, or if you're early in your career with decades of growth ahead.
Employer match dollars are always deposited on a traditional (pre-tax) basis, even in a Roth plan. The projection above intentionally doesn't model the tax bill either way — the balance shown is the pre-withdrawal number for both.
Projections are illustrative, based on the assumptions you set — not guarantees. Real market returns are volatile and unpredictable. This tool is not a substitute for a licensed financial advisor.

Compare the conservative and optimistic projections — nominal AND today's-dollars — and check the benchmark card to see whether your current balance is on pace for your age.
Retirement Calculator — 401(k) Projection with an Honest Range, No Account Linking
Free retirement and 401(k) calculator that projects your balance at retirement age as a conservative-to-optimistic range, models a real tiered employer match, shows both nominal and inflation-adjusted values, and estimates monthly retirement income under the 4% rule. No account linking, no signup.
Skycally's Retirement Calculator answers the question every 401(k) or IRA calculator is trying to answer — 'how much will I have?' — but does it honestly. Most retirement calculators, including the ones from big personal-finance sites, show a single confident number like '$1,842,391 at retirement!' as if the market's next 30 years were already decided. Nobody knows what returns will look like over 20 to 40 years, so this tool projects your balance across two return assumptions side by side — a conservative one and an optimistic one — and shows both. That's the same 'range, not false precision' honesty principle we apply everywhere else on the site. The number that matters isn't a single point estimate; it's how wide the range is and whether the low end still gets you where you need to be.
The other honesty problem in these calculators is how they model your employer's 401(k) match. Almost every competitor models it as a flat 'add X%' — which is wrong. Real matches are tiered, structured like 'we'll match 100% of the first 3% of salary you contribute, plus 50% of the next 2%.' That formula means the match amount changes with your contribution rate and your salary, and it caps out at a threshold most people don't realize is a threshold. This calculator models the match the way it actually works: two configurable tiers (matchPct + salary-cap%), recomputed against your current-year salary every year of the projection, with a first-year breakdown showing exactly how much 'free money' the match adds. If you're contributing below the match cap, we call it out — that gap is one of the highest-leverage fixes in personal finance.
The third honesty problem is inflation. A 'you'll have $2M at 65!' headline over a 35-year horizon can be almost entirely inflation illusion — at 2.5% inflation, $2M in 35 years buys roughly what $842K buys today. That's why every projection here shows both the nominal (future-dollar) balance and its inflation-adjusted value in today's dollars, clearly labeled. The monthly-income estimate under the classic 4% safe-withdrawal rule is computed on the today's-dollars number, because that's the figure that actually reflects what your savings would buy at the grocery store, not what the printed statement will say. If your projection halves after inflation, that's not a bug in the tool — it's the number every other calculator is quietly hiding from you.
This calculator fits alongside Skycally's other financial planning tools: the Compound Interest Calculator to model a separate taxable investment account alongside your 401(k) projection, the Paycheck Calculator to see exactly how a higher contribution percentage changes your real take-home pay after federal, state, and FICA, and the Debt Payoff Calculator if you're weighing 401(k) contributions against paying down high-interest debt faster. Every tool runs 100% in your browser — no account linking, no signup, no data sent anywhere.
Frequently Asked Questions
How much should I have saved for retirement by my age?
The widely cited Fidelity rule of thumb is roughly 1× your salary saved by age 30, 3× by 40, 6× by 50, 8× by 60, and 10× by age 67. So at age 40 earning $75,000, the benchmark would be about $225,000 saved. These are rules of thumb — not personalized recommendations — but they're useful for a quick 'behind pace / on pace / ahead of pace' gut check, which is exactly what the benchmark card on this calculator shows.
How does a 401(k) employer match actually work?
It's tiered, almost never a flat percentage. A very common formula is '100% match on the first 3% of your salary you contribute, plus 50% match on the next 2%.' If you make $75,000 and contribute 5%, that's $2,250 (100% match on the first 3% = $2,250) + $750 (50% match on the next 2% = $750) = $3,000 in employer money on your $3,750 contribution. If you only contribute 2%, you get $1,500 match and completely miss the second tier. This calculator lets you enter your plan's actual formula (two tiers) instead of forcing you to guess a single blended percentage.
What's the difference between a Traditional and a Roth 401(k)?
Traditional 401(k): contributions come out of your paycheck pre-tax (you get the tax break today), and every dollar you withdraw in retirement is taxed as ordinary income. Roth 401(k): contributions are after-tax (no tax break today), but qualified withdrawals in retirement — including all the market growth — are completely tax-free. Rough rule: Traditional is often better if you expect to be in a lower tax bracket in retirement than you are today; Roth is often better if you expect to be in the same or higher bracket. Employer match dollars are always deposited pre-tax, even into a Roth plan.
How much retirement income will my savings actually provide?
The classic guideline is the 4% rule: you can safely withdraw roughly 4% of your portfolio in the first year of retirement, adjust for inflation each year after, and have a high probability of the money lasting 30 years. So a $1 million balance would generate about $40,000 in the first year, or roughly $3,333/month. This calculator applies the 4% rule to the today's-dollars balance (not the nominal one), because that's the honest estimate of purchasing power at retirement.
What is the 4% rule?
The 4% rule is a widely used retirement withdrawal guideline from the 'Trinity Study' (a 1998 analysis of historical US market returns). It says a retiree who withdraws 4% of their portfolio in year one and adjusts that dollar amount for inflation each year after has historically had a high probability of the money lasting at least 30 years. It's a rule of thumb, not a guarantee — sequence-of-returns risk, unusually long retirements, and future market conditions can all change the safe withdrawal rate. Some analysts now argue for 3.5% or even a variable withdrawal strategy.
What investment return should I assume for retirement projections?
There's no right single answer, which is why this calculator uses two. A commonly used long-term nominal return assumption for a diversified stock-heavy portfolio is around 7–10%, and around 4–6% for a more bond-heavy or conservative allocation. Real (inflation-adjusted) returns are historically about 3 percentage points lower. Sensible defaults for someone in accumulation phase are roughly 5% conservative and 8% optimistic — but the whole point of showing a range is that reasonable people disagree. If the conservative projection still gets you where you need to be, your plan is robust.
Should I pay off debt or contribute more to my 401(k)?
The math-only answer: capture at least the full employer match before doing anything else — that's an instant guaranteed 50–100% return. After that, compare the interest rate on your debt to your expected investment return. Debt at 15%+ (like credit cards) almost always wins over stock returns; debt at 4% (like an old mortgage) almost always loses to long-run market returns. In the messy middle (student loans at 6–8%), it's closer to a coin flip and psychology matters. See the Debt Payoff Calculator to model the debt side of that trade-off explicitly.
Are these projections adjusted for inflation?
Yes — both. Every projection card shows the nominal (future-dollar) balance and, right beside it, the inflation-adjusted value in today's dollars. The monthly retirement income estimate under the 4% rule is applied to the today's-dollars balance, because that's the honest number for what your savings would buy at the grocery store in retirement. A nominal-only headline number is the single most common way retirement calculators mislead people about a 20–40 year projection — inflation quietly eats a huge share of the 'wow' figure.
