FAQ
The math, explained.
What is a savings rate? +
It’s the percentage of your take-home pay you keep and invest, not spend. Savings rate = (income − expenses) ÷ income. A $80k take-home with $40k spending puts you at 50%.
Why does savings rate matter more than income? +
A higher income means nothing if spending rises with it. The MMM table shows a 50% saver retires in ~17 years regardless of whether they earn $60k or $600k — the ratio, not the dollar figure, sets the clock.
How are the years-to-retirement numbers derived? +
They assume a 5% real (inflation-adjusted) return and a 4% safe withdrawal rate. The math: time to reach 25× your expenses, given you’re saving (1−rate)×income and spending rate×income.
Is 50% realistic? +
For most people, no — the US average hovers around 5–10%. But 30–50% is common in the FIRE community, often via geographic arbitrage, house hacking, or simply not inflating lifestyle with income.
Is this financial advice? +
No. It’s an educational tool based on transparent assumptions. Your real returns will vary. For decisions specific to your situation, speak with a licensed financial advisor.
How this number is calculated
Savings rate = (Take-home pay − Expenses) ÷ Take-home pay. The years-to-retirement table is the classic Mr. Money Mustache chart, assuming a 5% real return and 4% SWR — so 25× expenses is the target.
Read the original MMM savings rate article or why we use 7% average returns (the 5% real figure is 7% nominal minus ~2% inflation).
This tool is for educational purposes only and is not financial advice. Estimates are based on the assumptions shown (e.g., 7% nominal returns, 3% inflation, 4% withdrawal rate). Actual investment returns vary. Consider speaking with a licensed financial advisor.
