How It Works
Enter current age, life expectancy, savings, expected return, bequest, and inflation rate. The tool plans annual spending to deplete savings by end of life. Inspired by Bill Perkins, enter savings, life expectancy, expected return, inflation, and desired bequest. The tool computes inflation adjusted annual spending that depletes balance to the bequest by end of life. A 60 year old with $800,000, life expectancy 90, 6% return, 3% inflation, and zero bequest might spend roughly $48,000 year one rising with inflation. Subtract expected Social Security present value from required portfolio savings before annuity calculation for cleaner result. Inspired by Bill Perkins, enter savings, life expectancy, expected return, inflation, and desired bequest. The tool computes inflation adjusted annual spending that depletes balance to the bequest by end of life. Enter age, net worth, annual spending, expected return, and legacy target percent to see optimal drawdown path toward zero at life expectancy.

Review annual withdrawal amount, year by year balance trajectory, depletion age, and total amount withdrawn over your lifetime. Setting bequest to zero maximizes lifetime consumption. A positive bequest reduces annual withdrawals to preserve inheritance for heirs. Year by year table shows balance path. Depletion age should match life expectancy when bequest target is met exactly. Toggle bequest from zero to $100,000 to see annual spending reduction tradeoff for inheritance goals. Setting bequest to zero maximizes lifetime consumption. A positive bequest reduces annual withdrawals to preserve inheritance for heirs. Die with zero philosophy trades legacy for lifetime consumption: lower legacy percent raises annual spend recommendation. Setting bequest to zero maximizes lifetime consumption. A positive bequest reduces annual withdrawals to preserve inheritance for heirs. Die with zero philosophy trades legacy for lifetime consumption: lower legacy percent raises annual spend recommendation. Setting bequest to zero maximizes lifetime consumption.

Common mistakes
Copying outputs without checking input units or stale market prices is a frequent error with Die with Zero Calculator. Confirm tickers, percentages, and dates before acting.
Running a single baseline scenario ignores tail risks. Stress test with conservative inputs and compare against related tools listed below when the decision is material.
The Formula
Annual Withdrawal = (Savings - Bequest / (1+r)^years) / annuityFactor(r, years). AnnuityFactor = (1 - (1+r)^-years) / r. Withdrawal grows by inflation each year. Balance depletes to bequest by life expectancy.
Inflation adjusted withdrawals. Bequest honored at end of projection. Annuity factor ensures full depletion. Fixed return path ignores sequence risk. Pair with Monte Carlo tool for probability based planning. Longevity risk beyond life expectancy table requires manual buffer in bequest field. Fixed return path ignores sequence risk. Pair with Monte Carlo tool for probability based planning. Life expectancy is average not guaranteed: conservative planners add five to ten years to horizon input. Fixed return path ignores sequence risk. Pair with Monte Carlo tool for probability based planning.

FAQ
How is the annual withdrawal calculated?
The tool calculates an annuity payment that draws down savings to exactly a specified bequest by life expectancy, factoring in expected return and inflation adjusted withdrawals. Annuity math spreads spending evenly in present value terms while nominal withdrawals rise with inflation each year. Social Security and pensions reduce required portfolio draw: subtract guaranteed income before entering savings. Annuity math spreads spending evenly in present value terms while nominal withdrawals rise with inflation each year. Longevity risk means outliving zero target is catastrophic: pad spending plan with floor from annuities or delayed Social Security. Annuity math spreads spending evenly in present value terms while nominal withdrawals rise with inflation each year. Longevity risk means outliving zero target is catastrophic: pad spending plan with floor from annuities or delayed Social Security. Annuity math spreads spending evenly in present value terms while nominal withdrawals rise with inflation each year.
What is the bequest present value?
Annual Withdrawal = (Savings - Bequest_PV) / annuityFactor(r, remaining years). Bequest_PV discounts the desired bequest to present value using the expected return rate. Bequest present value discounts the target inheritance back to today using your return assumption before computing spendable amount. Larger bequest suits heirs or charity: model tradeoff explicitly rather than defaulting to maximum spending. Bequest present value discounts the target inheritance back to today using your return assumption before computing spendable amount. Health spikes in final years may exceed smooth spending curve: keep unmodeled reserve for long term care outside optimizer. Bequest present value discounts the target inheritance back to today using your return assumption before computing spendable amount. Health spikes in final years may exceed smooth spending curve: keep unmodeled reserve for long term care outside optimizer. Bequest present value discounts the target inheritance back to today using your return assumption before computing spendable amount.
How does inflation adjustment work?
Each year the withdrawal increases by the inflation rate so spending power is maintained. Balance = Balance × (1 + r) - Withdrawal, year after year until depletion. Real spending power stays flat when withdrawals grow exactly with inflation. Higher inflation with fixed nominal spending erodes lifestyle. Medical inflation may exceed CPI: stress test inflation 2 points above baseline for conservative planning. Real spending power stays flat when withdrawals grow exactly with inflation. Higher inflation with fixed nominal spending erodes lifestyle.
Should I set the bequest to zero?
A bequest of zero maximizes lifetime spending. Setting a positive bequest reduces annual withdrawals to preserve an inheritance. Depletion age shows when the balance drops near the bequest. Many retirees underspend relative to capacity due to fear of outliving assets. Zero bequest shows the upper bound of sustainable spending. Charitable bequests can be modeled as positive bequest reducing spendable amount while funding legacy goals. Couples should run joint life expectancy and survivor spending scenarios outside single life table defaults. Many retirees underspend relative to capacity due to fear of outliving assets. Zero bequest shows the upper bound of sustainable spending. Real spending should track inflation: rerun with higher annual spending when healthcare share of budget rises with age.

How do I explore different scenarios?
Adjust life expectancy, expected return, inflation, and bequest amount. Higher returns or shorter life expectancy increase annual spending. Inputs are saved locally. Lower expected return by 1 to 2 points to stress test longevity risk from poor market decades. Compare annual withdrawal to 4% rule benchmark on same inputs for familiar reference point.

Giving while living shifts legacy target: model charitable gifts as spending spikes in high energy years.
