How much do you need to save to retire early?
Early retirement generally requires 25–30× annual spending invested, which is $1.25M–$1.5M for a $50,000 lifestyle. Savings rate matters far more than return: saving 50% of income reaches financial independence in roughly 17 years, while 15% takes over 40.
Years to financial independence by savings rate
| Savings rate | Years to FI | Assumption |
|---|---|---|
| 10% | ~51 years | 5% real return |
| 20% | ~37 years | 5% real return |
| 30% | ~28 years | 5% real return |
| 50% | ~17 years | 5% real return |
| 65% | ~10.5 years | 5% real return |
| 75% | ~7 years | 5% real return |
How to read this table
- 10% sits at the top of the table (~51 years) — 5% real return. If your situation looks like this row, plan against the upper half of the range rather than the midpoint.
- 75% anchors the bottom (~7 years) — 5% real return. Treat this as the conservative case you should still be profitable at.
- The gap between the top and bottom row is roughly 7.3×. That spread is why a single blended average is close to useless here — pick the row that matches your setup instead of averaging the column.
- With 6 reference points in the "years to financial independence by savings rate" table, the fastest way to use this page is to find the closest row, take its years to fi, then stress-test it ±30% before you build a plan on it.
Context
Savings rate does double duty: it raises the amount invested and lowers the spending the portfolio has to support, which is why the curve bends so sharply. The bigger risks in early retirement are not arithmetic. Sequence-of-returns risk — a bad market in the first five years of withdrawals — does more damage than a lower average return, and health coverage before Medicare eligibility is the single largest unbudgeted line for US early retirees. A cash or bond buffer covering two to three years of spending is the standard mitigation.
What moves this number
Time-for-money versus asset-building
Gig and freelance work pays immediately and stops when you stop. Content, products and rentals pay nothing for months and then keep paying without proportional hours.
Real cost per hour
Fuel, vehicle depreciation, platform commission and self-employment tax routinely turn a $28 gross hour into an $17 net one.
Hours actually available
Most side income projections assume 15–20 consistent weekly hours. Model the hours you will still work in month six, not month one.
Tax treatment
Side income is generally self-employment income, carrying a 15.3% payroll-equivalent tax on top of income tax and requiring quarterly estimates once it grows.
Methodology
Standard FI math using a 4% withdrawal rate and 5% real return, with years-to-FI derived from savings rate on take-home pay.
Assumptions and caveats
- Amounts are gross of self-employment tax and any platform or payment fees not noted in the row.
- Earnings assume consistent weekly hours; most side income declines sharply after the first few months.
- This page was last reviewed on 2026-08-12. Ranges are updated as new data lands, so re-check before using them in a contract or a plan.
- Use these numbers as a starting range, not a guarantee — your own historical data always beats a benchmark.
Frequently asked questions
How much do you need to save to retire early?
Early retirement generally requires 25–30× annual spending invested, which is $1.25M–$1.5M for a $50,000 lifestyle. Savings rate matters far more than return: saving 50% of income reaches financial independence in roughly 17 years, while 15% takes over 40.
Which option pays the most in the years to financial independence by savings rate table?
10%, at ~51 years (5% real return). That row represents the strongest case in this dataset, so use it as an upper bound rather than an expectation.
What is a realistic low-end figure?
75% at ~7 years (5% real return). Plan your costs so the low end still works, then treat anything above it as upside.
Why do the numbers vary so much?
The spread between the highest and lowest row is about 7.3×. Time-for-money versus asset-building and real cost per hour explain most of that gap — see the drivers section above for the full list.
Where do these numbers come from?
Standard FI math using a 4% withdrawal rate and 5% real return, with years-to-FI derived from savings rate on take-home pay.
How can I estimate my own number instead of using a benchmark?
Use the FIRE Number Calculator on RevenueLab — it takes your own inputs and returns a figure specific to your setup, which is always more accurate than a published range.
