What's a Good Savings Rate? Why It Beats Your Salary
By the Stoia team · July 11, 2026 · 7 min read
Ask most people how they're doing financially and they'll tell you their salary. But salary is the wrong scoreboard. The number that actually predicts when you reach financial independence is your savings rate: the percentage of your take-home pay you keep instead of spend.
What a savings rate is
It's simple math on after-tax income:
Savings rate = (money saved or invested ÷ take-home pay) × 100
Take home $5,000 a month and invest $1,000 of it? That's a 20% savings rate. Count anything that builds net worth: 401(k) and IRA contributions (plus the employer match), brokerage deposits, and extra principal on debt all belong in the numerator.
Why it beats your salary
Your savings rate pulls two levers at once, which is why it's so powerful:
- It shrinks the target. Living on less lowers your annual spending — and your FIRE number is 25× that spending. Spend less, and the finish line moves toward you.
- It grows the fuel. Every dollar not spent is a dollar invested, compounding for decades.
A $200,000 earner who spends $190,000 is further from freedom than a $70,000 earner who spends $42,000. The raise helps only if it widens the gap between what you make and what you spend.
Savings rate vs. years to financial independence
Here's the part that reframes everything. Starting from zero and assuming a ~5% real return with a 4% withdrawal at the end, your savings rate alone roughly sets your timeline:
| Savings rate | Approx. years to financial independence |
|---|---|
| 10% | ~51 years |
| 15% | ~43 years |
| 20% | ~37 years |
| 30% | ~28 years |
| 40% | ~22 years |
| 50% | ~17 years |
| 65% | ~10.5 years |
The jump from 10% to 20% doesn't just double your saving — it cuts roughly 14 years off the wait. Notice your salary isn't in this table at all.
So what's a good rate?
- 10–15% — the traditional "retire in your mid-60s" default. A fine floor, not a fast track.
- 20% — the savings slice of the 50/30/20 rule, and a genuinely solid target for most households.
- 30–50%+ — the FIRE zone, where retirement becomes a question of years rather than decades.
How to raise yours
Rates move fastest at the extremes of your budget. Give every dollar a job with the 50/30/20 budget calculator, then squeeze the two biggest line items — housing and transportation — because a 10% cut there beats cancelling ten small subscriptions. Route every raise, bonus, and tax refund straight to investments instead of letting spending expand to match. Then let time do the heavy lifting: run your numbers through the compound interest calculator and watch a higher rate bend the curve.
Track your rate the same way you track your net worth — monthly, as a trend. What gets measured tends to climb.
