Retirement Withdrawal Calculator: Estimate How Long Your Money May Last

A retirement withdrawal calculator is a tool that estimates how much you can withdraw from your savings each year and how long your money may last. It uses inputs like your starting balance, withdrawal amount, rate of return, and inflation to project future outcomes.
This helps retirees and pre-retirees understand whether their current withdrawal strategy appears sustainable.

Retirement Withdrawal Calculator

Estimate how long your retirement savings may last based on your balance, withdrawals, and assumed annual return.







This calculator provides hypothetical estimates only and does not guarantee future results, withdrawal sustainability, or investment performance.

How to Use the Calculator

Follow these steps to estimate your retirement income:

  • Enter your starting retirement balance
  • Add your planned annual withdrawal amount
  • Choose an assumed annual rate of return
  • Include an inflation rate to adjust withdrawals over time
  • Enter how many years you want to project
  • Review your results and yearly breakdown

The calculator will show:

  • Estimated ending balance
  • How long your portfolio may last
  • Year-by-year withdrawal and growth details

What Affects How Long Your Money Lasts?

Several key factors determine whether your retirement savings will last:

Withdrawal Amount

The more you withdraw each year, the faster your portfolio may decline.

Investment Returns

Higher returns may help extend your savings, while lower returns can shorten your timeline.

Inflation

Inflation increases your cost of living and may require higher withdrawals over time.

Taxes

Taxes reduce your net returns and can impact sustainability.

Time Horizon

The longer your retirement, the more important it is to manage withdrawals carefully.

Example Retirement Withdrawal Scenario

Here’s a simple example:

  • Starting balance: $750,000
  • Annual withdrawal: $40,000
  • Expected return: 5%
  • Inflation: 2%
  • Time horizon: 30 years

This scenario helps illustrate whether your savings may last through retirement based on your assumptions.

What Is a Safe Withdrawal Rate?

A safe withdrawal rate is the percentage of your portfolio you withdraw each year without running out of money too quickly.

A commonly used guideline is the 4% rule, which suggests withdrawing 4% in your first year of retirement and adjusting for inflation each year after.

However, the right withdrawal rate depends on:

  • Your retirement length
  • Investment strategy
  • Other income sources (Social Security, pensions, annuities)
  • Risk tolerance

Using a calculator helps you test different withdrawal rates instead of relying on a single rule.

Important Limitations

This calculator provides a simplified estimate. Real retirement outcomes depend on:

  • Market volatility and sequence of returns
  • Taxes and account structure
  • Healthcare costs and unexpected expenses
  • Changes in spending over time
  • Longevity and lifestyle choices

Results should not be considered guarantees.

This calculator is useful if you want to:

  • Estimate how long your savings may last
  • Plan retirement income strategies
  • Compare different withdrawal amounts
  • Understand the impact of inflation
  • Prepare for a 20–30 year retirement
