The table that changes everything
Years needed starting from zero, using your real return and withdrawal rate. Your row is highlighted.
| Savings rate | Years to FI | Fraction of working life* |
|---|
*Based on a reference working life of 40 years. Financial independence isn't a question of how much you earn — it's about the gap between what you earn and what you spend: every extra point of savings rate pulls the goal forward twice over — you accumulate more and need less. Figures are real (already inflation-adjusted) and for illustration only; markets don't deliver constant returns (see the portfolio projector for sequence-of-returns risk).
What each number means
A quick look at each field and result.
What fraction of your income you manage to save. It's the variable that carries the most weight in this whole calculation — more than your investment return.
The return already adjusted for inflation — unlike other calculators on this site, this one asks for the real rate directly, not the nominal one.
The annual percentage you'll withdraw once you get there (the classic 4% rule, or something more conservative).
What you've already saved, expressed as a multiple of your annual spending — not in dollars. If your annual spending is $24,000 and you have $12,000 saved, enter 0.5 here.
The headline result: how many years (and months) remain under these assumptions.
The same calculation repeated for different savings rates, with yours highlighted — so you can see at a glance how much each extra point of savings pulls the goal forward.
How to fill out this calculator
Steps to estimate your remaining years (expand)
- Move the savings rate slider. It's the variable that matters most, more than returns: raise your savings rate and you'll see the goal come closer much faster than by raising your return.
- Enter your real annual return. Careful: this field asks for the return already adjusted for inflation, not the nominal figure. If you're starting from a 7% nominal return with 2% inflation, enter 5.
- Set your target withdrawal rate. The classic 4%, or something more conservative if you'd rather have a margin of safety.
- Enter what you've already saved as a multiple of your annual spending. Not in dollars: if you spend $24,000 a year and have $12,000 saved, enter 0.5 here.
- Read the table with your row highlighted. There you can see at a glance how many years each additional point of savings rate saves you.
Frequently asked questions about this calculator
Why does the savings rate matter more than investment returns?
Because it works twice over: saving more builds more capital and reduces the spending that capital needs to cover. Returns, by contrast, only help in one direction — and they're not something you control.
Why is "Already saved" entered as a multiple of annual spending instead of dollars?
So the calculation works the same regardless of your spending level, without having to enter it twice. Divide what you've already saved by your desired annual spending, and that's the number that goes here.
Why does this calculator ask for a "real" return when other calculators separate out inflation?
For simplicity in this particular table: by asking directly for the already-adjusted figure, the result in years comes out clean without carrying two variables. If you'd rather start from a nominal return, subtract your inflation estimate before entering it here.
How does this relate to the "FI number" calculator?
That calculator gives you the destination: how much capital you need. This one gives you the route: how many years remain to get there, based on your savings rate. Use them together: FI number calculator.
