Calculator to Estimate How Long a Retirement Corpus Will Last
Enter your starting corpus(savings), planned annual withdrawals, expected growth and inflation,
and an estimated tax rate on growth. We’ll compare two scenarios side-by-side and
show cumulative withdrawals and how long your corpus will last for both the scenarios.
You can change the inputs for both the scenarios below as per your situation. They have been pre-filled just for convenience.
Tip: For taxable accounts, people often try 15–20% as a first-pass tax rate on growth.
Tax treatment varies by country and account type.
Planning for financial independence requires a clear understanding of how long your
retirement corpus will sustain your lifestyle. This retirement
calculator is designed to help you estimate the lifespan of your savings by
comparing different side-by-side scenarios. By factoring in crucial economic variables—such
as inflation rates, expected investment growth, and
estimated taxes on growth—you can stress-test your portfolio against
real-world conditions. Whether you are mapping out a tiered drawdown strategy
across your Go-Go, Slow-Go, and No-Go years, or simply determining your ideal
retirement age, visualizing how your nest egg devalues
or grows over time is essential. Use this tool to run the numbers, fine-tune your
inflation-adjusted withdrawals, and build a more resilient, long-term
retirement income plan.
