Savings Rate Calculator
The share of your pay you don't spend decides when you can stop working — more than your salary does, and more than your investment returns do. Find yours below.
Savings Rate Calculator
Your savings rate is the share of your pay you don't spend. It sets your retirement date more than your income or your returns do — enter your numbers to see yours.
Your salary before any deductions, plus bonuses.
Everything withheld before the money reaches you. Leaves $63,750 of take-home pay.
Everything you invest each month — 401(k), IRA, brokerage, and any employer match.
Invested assets only. Not your emergency fund or home equity.
Use a real (after-inflation) return — 5–7% for a stock-heavy portfolio — so today's spending stays comparable.

You live on $49,350 a year, so your FIRE number is $1,233,750 — 25× your spending. Your $1,200 a month plus $25,000 already invested, growing at 5% a year, gets you there around December 2058.
What five points of savings rate are worth
Same income, same returns — only the share you keep changes.
Each row assumes you invest that share of your $63,750 take-home pay and live on the rest, so spending — and the 25× FIRE number it implies — moves with it.
What is a good savings rate?
The rule of thumb you'll hear most often is 15% of gross income. It isn't arbitrary: 15% saved from your mid-twenties, compounding for forty years, lands you at a conventional retirement in your mid-sixties. It answers the question “when can I retire at the normal time?” — which is a different question from “when can I retire?”
Read the rate as a date instead of a grade. Every savings rate implies a retirement year, and once you see the pairing, the choice gets easier:
- Under 10% — the timeline runs past a working lifetime. Fine as a starting point after a raise or a paid-off debt; a problem as a destination.
- 15–20% — the standard advice. Retire at a normal age with a portfolio that replaces your spending.
- 30–40% — where early retirement starts to be real. Two decades of work rather than four.
- 50% and above— financial independence inside seventeen years, from zero. This is the FIRE movement's headline number, and it usually needs either an unusual income or an unusually cheap life.
One caveat worth stating plainly: a savings rate you can't hold isn't a savings rate, it's a January resolution. A steady 25% beats a 50% that collapses in month seven and takes your emergency fund with it. Build the cash buffer first, then push the rate as high as it will stay.
How savings rate affects your retirement timeline
Here is the whole argument in one table. Starting from zero, investing that share of your take-home pay and living on the rest, at a 5% real return, retiring when your portfolio reaches 25× your annual spending:
| Savings Rate | Years to FIRE | What it means |
|---|---|---|
| 5% | 66 years | Retirement never really arrives |
| 10% | 51 years | A full career of work |
| 15% | 43 years | Close to the standard 15% advice |
| 20% | 37 years | Start at 25, finish at 62 |
| 25% | 32 years | A few years early |
| 30% | 28 years | Where early retirement begins |
| 40% | 22 years | Out before 50 |
| 50% | 17 years | The classic FIRE benchmark |
| 60% | 12 years | Demands a low cost of living |
| 70% | 9 years | Rare, and usually high-income |
Notice what the table doesn't contain: your income. A surgeon and a teacher who each save 15% of their take-home pay retire after the same number of years — the surgeon just does it on a bigger boat. Your savings rate is a ratio, and ratios don't care about scale.
The reason is that a dollar you don't spend does two jobs at once. It goes into the portfolio, and it comes out of the spending your portfolio has to cover for the rest of your life — so it lowers the target by 25 times itself while raising the balance. That's why the first ten points of savings rate buy fourteen years (10% to 20%), while the last ten buy three (60% to 70%). The curve is steepest exactly where most people are standing.
It's also why a raise is worth so much less than it looks. Spend all of it and your savings rate falls, your spending rises, and your retirement date moves away. Save all of it and it moves toward you twice. What compounding does to those dollars over the following decades is the third job, and the reason early savings outrun late ones.
Savings rate by income level
What a target rate asks of you in dollars, before tax. Find your income, then read across to the monthly amount:
| Gross Income | 10% rate | 20% rate | 30% rate |
|---|---|---|---|
| $40,000 | $333/mo | $667/mo | $1,000/mo |
| $60,000 | $500/mo | $1,000/mo | $1,500/mo |
| $80,000 | $667/mo | $1,333/mo | $2,000/mo |
| $100,000 | $833/mo | $1,667/mo | $2,500/mo |
| $150,000 | $1,250/mo | $2,500/mo | $3,750/mo |
| $250,000 | $2,083/mo | $4,167/mo | $6,250/mo |
The rows differ; the logic inside each column doesn't. Two people saving the same share of their pay reach financial independence after the same number of years, whichever row they're standing in, because each lives on the remainder and each needs 25 times that remainder. The $250,000 earner gets a far more comfortable version of the timeline — not a shorter one.
Where income genuinely helps is the gapbetween what you earn and what a decent life costs. Fixed costs — rent, food, a car — don't scale with your salary, so a higher income makes a high savings rate easier to reach without sacrifice. A 40% rate on $150,000 leaves $90,000 to live on. The same rate on $50,000 leaves $30,000, and that is a genuinely different life. The math is identical; the difficulty is not.
This also cuts the other way. Lifestyle creep is the mechanism by which a doubled salary produces an unchanged savings rate and an unchanged retirement date. The defense is to route raises straight into the investment account before they reach your checking account.
What the calculator assumes
Three assumptions sit behind the projected date, and each is worth knowing before you trust it:
- Your spending is your take-home pay minus savings. That is what makes a savings rate a retirement date. It also means the tax percentage you enter matters — if your monthly savings figure includes pre-tax 401(k) money, that money isn't in your take-home pay, so lower the tax percentage accordingly.
- The 4% rule sets the finish line.Financial independence arrives at 25× annual spending. A retirement lasting 40 or 50 years arguably calls for 3.25–3.5% instead, which raises the target to roughly 29–31×. The FIRE calculator lets you set the withdrawal rate directly and see the cost of that margin.
- The return is real, not nominal.Enter an after-inflation figure — 5–7% for a stock-heavy portfolio — so that today's spending and tomorrow's portfolio are measured in the same dollars. Feeding a 10% nominal return into a plan denominated in today's spending will invent years you don't have.
And a fourth thing the calculator can't know: your savings rate will not be a constant. It rises with raises and falls with children, houses, and the years you have to replace a roof. Re-run it annually. The number that matters is the average across a career, not the one you can hit in a good month.
If your balance is already large, check Coast FIRE before you push the rate higher — you may have already saved enough for compounding to finish the job on its own, in which case the useful lever is a shorter career, not a leaner one.

Frequently Asked Questions
How do I calculate my savings rate?
Divide what you save in a year by what you earn in a year. Saving $1,200 a month — $14,400 a year — on an $85,000 salary is a 16.9% gross savings rate. Count every dollar you invest, including your 401(k) contributions and your employer's match, because both are money you earned and didn't spend.
What is a good savings rate?
A common rule of thumb is 15% of gross income, which is aimed at a normal retirement in your mid-sixties after decades of compounding. Anything above 20% pulls that date forward, 30–40% is the range most people pursuing early retirement land in, and 50%-plus is what puts financial independence inside two decades. The honest answer is that a good savings rate is the one that matches the date you want to stop working — pick the date, then read the rate off the table above.
Should I calculate my savings rate on gross or net income?
Both are used, so say which you mean. Gross income is the bigger denominator, so it produces a smaller and more conservative number, and it's the one most people quote. Take-home pay is the more useful denominator for retirement math: what you don't save out of it is what you actually spend, and your spending sets the size of the portfolio you need. This calculator shows both, and uses the take-home figure to work out the timeline.
How much should I save per month?
Work backwards from a target rather than picking a round number. Multiply your gross income by the savings rate you're aiming for and divide by twelve: a 20% rate on $75,000 is $1,250 a month. If you have a retirement date in mind, enter it as a target year above — the calculator solves for the exact monthly figure that reaches financial independence by then.
Does my 401(k) employer match count toward my savings rate?
Yes. It's compensation you didn't spend, it compounds in your account like everything else, and leaving it out understates a rate that your retirement date is actually going to reflect. Count the match in the numerator, and count it in your gross income in the denominator too if you want to be strict about it.
Does paying off debt count as saving?
For your retirement timeline, no — paying down a loan raises your net worth but doesn't build the portfolio you'll withdraw from. It does something better, though: it permanently lowers your spending, which lowers your FIRE number by 25 times the annual payment you eliminate. Clearing a $400-a-month loan takes $120,000 off the target and frees $400 a month to invest.
Why does a higher savings rate shorten retirement twice over?
Because the same dollar appears on both sides of the equation. A dollar you don't spend is a dollar invested, and it's also a dollar you never have to fund in retirement — so it raises your balance while lowering the number that balance has to reach. That's why going from a 10% to a 20% savings rate cuts roughly fourteen years off, while a raise you spend entirely cuts none.
What is the personal saving rate you see in the news?
The U.S. Bureau of Economic Analysis publishes a national personal saving rate each month: total personal saving as a percentage of disposable (after-tax) personal income, across the whole country. It's a macroeconomic aggregate, not a benchmark for a household. Your own rate — the one on this page — is the one that determines when you can stop working.
