About Safe Withdrawal
Convert a nest egg into the level monthly withdrawal that exactly exhausts it over your horizon.
This is the mirror of loan amortization: instead of paying a loan down, you draw savings down to zero over N years while the remainder keeps growing. The output is the maximum level monthly check the math supports.
The classic 4% rule is the same idea at 30 years and ~5% growth. Real retirements face inflation and sequence risk, so treat the result as a ceiling and keep a buffer. All math runs in your browser.
Where it is used
Retirement budgeting, testing whether savings last to life expectancy, and comparing growth assumptions.

Frequently Asked Questions
- What is the 4% rule?
- Withdraw 4% of savings in year one, then adjust for inflation yearly. It survived 30-year historical simulations; this calculator generalizes it to any horizon and return.
- Why is the rate above 4% here?
- Shorter horizons and higher assumed growth support bigger withdrawals. Stretch the horizon to 35+ years and the rate falls toward 4%.
- Does this account for inflation?
- No — outputs are nominal. For planning in today’s dollars, use an inflation-adjusted (real) return as the growth input.
