Why the savings rate matters more than income
It isn't how much you earn but what percentage you keep that decides how fast you get closer to financial independence.
The savings rate is the percentage of your net income that you save or invest each month instead of spending it. It is probably the single most important figure in all long-term financial planning, more important than absolute income or investment return.
The reason: the savings rate affects the time needed for financial independence in TWO ways at once. A higher rate means more built up each month AND lower yearly expenses to cover later (if you live on less, you need a smaller portfolio to support your lifestyle).
| Savings rate | Estimated time to independence (approximately) |
|---|---|
| 10% | over 40 years |
| 25% | ~32 years |
| 50% | ~17 years |
| 70% | ~9 years |
These figures are simplified estimates, based on standard return assumptions. Use the FIRE number calculator for a personal estimate based on your own figures.
In short
- The savings rate affects the time to independence more than absolute income.
- A higher rate cuts the time needed twice over: you build more AND need less.
- Even small rises in the rate (1 to 2 percentage points) have a significant compounding impact over the long term.
