Savings Rate Calculator
Last verified · Methodology
Find the percentage you actually save, then read your finish date straight off the table.
Your income and spending
Federal, state, FICA. Not 401(k) contributions, since those count as savings.
Everything you actually spend. What is left over is your savings.

Your savings rate
34.2%
Saving $25,000 per year, you reach financial independence in about 27.6 years starting from zero, at a 3.88% real return and a 4% withdrawal rate.

Income does not appear anywhere in this table. Only the percentage you keep matters.
| Savings rate | Years to FI | |
|---|---|---|
| 5% | 77.9 | |
| 10% | 59.7 | |
| 15% | 49.1 | |
| 20% | 41.6 | |
| 25% | 35.8 | |
| 30% | 31.1 | |
| 40% | 23.6 | |
| 50% | 17.8 | |
| 60% | 13.1 | |
| 70% | 9.1 | |
| 80% | 5.7 |
Assumes a 3.88% real return, a 4% withdrawal rate, and a starting balance of zero. Existing savings shorten every row.
What is a savings rate?
Your savings rate is the fraction of your take-home pay that you keep. Take-home pay minus spending, divided by take-home pay. It sounds trivial, and it is the most important number most people never calculate.
($70,000 − $50,000) ÷ $70,000 = 28.6%
Why income cancels out
The surprising part of the savings rate table is that salary never appears in it. The reason is that both sides of the equation scale together.
Raise your income and keep the same percentage, and you save more each year, which speeds things up. But you also spend more, which raises the portfolio you need in exactly the same proportion. The two effects cancel. A person saving 50% of $60,000 and a person saving 50% of $600,000 reach independence in the same number of years, on very different lifestyles.
The practical implication is that a raise only shortens your timeline if you save a larger share of it than you were saving before. Absorbing a raise fully into lifestyle leaves the date unchanged.
Savings rate benchmarks
| Savings rate | Roughly who | Years to FI from zero |
|---|---|---|
| 5% | Near the US median | About 65 years |
| 15% | Standard retirement advice | About 42 years |
| 25% | Diligent saver | About 32 years |
| 40% | Committed to early retirement | About 22 years |
| 50% | Serious FIRE pursuit | About 17 years |
| 70% | High income, low spending | About 8.5 years |
Figures assume a 5% real return, a 4% withdrawal rate, and a starting balance of zero. Existing savings shorten every row, sometimes dramatically.
Where the leverage actually is
Raising a savings rate has two effects at once, which is why it works so much harder than raising income. Cutting $500 per month from spending adds $6,000 per year to savings and removes $150,000 from a 4% rule target simultaneously.
- Housing. Usually 25% to 40% of take-home pay. One decision here outweighs a year of small optimisations.
- Transportation. Vehicle payments, insurance, and depreciation typically run second.
- Food. The gap between cooking and not cooking is often $400 to $800 per month for a household.
- Raises. Directing new income straight to investments raises the rate without any felt sacrifice.
Turn the rate into a dollar target
Once you know the rate, find the actual dollar target with the FIRE number calculator, which unlike the table above accounts for money you have already invested. If your current balance is meaningful, check whether you have quietly passed Coast FIRE already. To see what the contributions become over decades, use the compound interest calculator.
Your savings rate is the share of your take-home pay that you do not spend, expressed as a percentage. If you take home $70,000 and spend $50,000, you saved $20,000, which is a 28.6% savings rate. It is the single most useful number in personal finance because it sets both how fast the portfolio grows and how small the target needs to be.
The common benchmark is 15% to 20% for a conventional retirement at 65. For early retirement the numbers rise steeply: roughly 30% points to independence in about 28 years, 50% in about 17 years, and 65% in about 10 years. Median US household savings rates have generally run in the mid single digits, so anything above 20% already puts you well outside the norm.
Net, meaning take-home pay after taxes, is the more useful basis because taxes are not money you could have saved. Using gross income makes the rate look lower and varies with tax brackets rather than behavior. Whichever you pick, apply it consistently. Note that 401(k) contributions count as savings, not as taxes, even though they come out before your paycheck lands.
Because the target and the contribution both scale with income. Doubling your salary while doubling your spending leaves the timeline unchanged: you save twice as much per year, but you also need twice as large a portfolio. What actually moves the date is the percentage kept, not the dollars earned. That is the counterintuitive result behind every savings rate table.
Yes, substantially. The standard savings rate table assumes you are starting from zero, which makes it a clean comparison but a pessimistic one for anyone already invested. If you have meaningful savings already, use the FIRE number calculator instead, since it accounts for the head start you have.
Attack the three largest categories first. Housing, transportation, and food account for the majority of most budgets, and a change there outweighs dozens of small cuts. Saving a raise instead of absorbing it is the other reliable mechanism, because it raises the rate without requiring you to give anything up. Small recurring subscriptions get disproportionate attention relative to what they move.
