Early retirement calculator

Your savings rate — not investment return alone — is what most strongly shortens the path to financial independence.

Model assumes expenses stay flat, you keep saving the gap between income and expenses, and you aim for a nest egg large enough that withdrawals at your chosen rate cover those expenses without shrinking principal over the long run.

Savings rate vs years to retire

Holding expenses, return, and withdrawal rate fixed — higher savings rates cut years dramatically.

Your inputs: 50% savings → 16.6 years

Year-by-year path

When return on investments covers 100% of expenses, portfolio income matches spending. Your withdrawal-rate target ($1,250,000) usually means working a bit longer than that first “100% covered” year. ROI covers expenses around year 14.7.

50% savings rate

How it works

Enter after-tax income, current nest egg, and annual expenses. Savings equal income minus expenses; savings rate is that gap divided by income.

The nest egg target is annual expenses divided by your withdrawal rate (for example, $20,000 ÷ 4% = $500,000).

Years to retirement compound that nest egg with your assumed real return and ongoing savings. A year-by-year table shows when investment returns begin covering expenses.

Frequently asked questions

Why does savings rate matter more than return?
A higher savings rate both adds more each year and lowers the lifestyle you need to fund. Small changes in savings rate often move the retirement date more than modest changes in assumed market return.
What is a withdrawal rate?
It is the percentage of your portfolio you plan to spend each year in retirement. The well-known “4% rule” is a starting heuristic, not a guarantee—many planners stress-test lower rates.
Are these years a promise I can retire then?
No. This is an educational model with flat expenses, constant returns, and no job loss or market crashes. Use it to compare savings rates, then refine with a full financial plan.
