Safe Withdrawal Rate Calculator

Planning for a secure and comfortable retirement hinges on knowing how much you can withdraw from your savings each year without depleting your nest egg too quickly. The Safe Withdrawal Rate Calculator applies industry-standard guidelines like the 4% rule to help retirees and future retirees estimate a sustainable annual withdrawal rate. By factoring in portfolio value, expected rate of return, and inflation, this tool provides a clear picture of the income you can rely on throughout retirement.

In real life, retirees face the risk of outliving their savings. With rising life expectancies and market volatility, guessing a safe withdrawal rate can lead to either overly conservative spending or, worse, running out of funds. Financial planners and DIY investors often reference historical market data and Monte Carlo simulations to refine withdrawal strategies. Rather than wrestling with spreadsheets or complex financial models, this calculator delivers instant estimates, making retirement planning accessible for everyone.

Keywords like “safe withdrawal rate,” “retirement income calculator,” “4% rule calculator,” and “sustainable withdrawal rate” naturally align with searches by those seeking retirement guidance. Whether you're determining how much you can withdraw annualy from a million-dollar portfolio or comparing different withdrawal rules, this tool simplifies the math and supports informed decisions.

Formula for Safe Withdrawal Rate Calculator

The core calculation applies a withdrawal percentage to your current portfolio balance:

Annual Withdrawal Amount = Portfolio Value × Safe Withdrawal Rate

Where:
- Portfolio Value = Total retirement savings at the start of the year - Safe Withdrawal Rate = Chosen percentage (commonly 4%) - Annual Withdrawal Amount = Sustainable withdrawal for that year

Adjusting for Inflation

Next Year’s Withdrawal = Prior Year Withdrawal × (1 + Inflation Rate)

To maintain purchasing power, increase each year’s withdrawal by expected inflation (e.g., 2–3%). This ensures your retirement income keeps pace with rising living costs.

Breakdown for Beginners

Start with your current retirement portfolio balance. Multiply by the withdrawal rate you’re comfortable with (4% is conventional). The result is the first year’s income. Each subsequent year, adjust that amount by estimated inflation so your real income remains stable.

Example of Safe Withdrawal Rate Calculator

Suppose you have ₹75,00,000 in retirement savings and choose a 4% withdrawal rate, with an expected 2% annual inflation adjustment.

Year 1 Withdrawal = ₹75,00,000 × 0.04 = ₹3,00,000

For Year 2, adjust for inflation:

Year 2 Withdrawal = ₹3,00,000 × (1 + 0.02) = ₹3,06,000

Over a 30-year retirement horizon, this approach balances spending needs against the risk of portfolio depletion. Instead of manually recalculating each year, simply enter your portfolio value, withdrawal rate, and inflation assumption into the calculator to generate a full withdrawal schedule instantly.
