About the Retirement Calculator

Estimate how much you could have by retirement and how long it might last. Enter your age, savings and contributions to build a simple retirement plan.

How to use the Retirement Calculator

  1. Enter your Current Age and planned Retirement Age.
  2. Enter Current Savings ($), your Monthly Contribution ($) and the Annual Return (%) you expect.
  3. Enter the amount you want to withdraw each month under Post-Retire Withdraw ($/mo).
  4. Press Generate Retirement Plan to see your projected nest egg and how long withdrawals could last.

Formula and method

The projected balance uses compound growth on current savings plus the future value of monthly contributions: FV = S(1 + i)ⁿ + PMT × ((1 + i)ⁿ − 1) ÷ i. Withdrawals are then subtracted month by month while the remaining balance continues to earn returns.

Worked example

A 30-year-old with $20,000 saved, adding $500 a month at 7% until 65, could reach about $1.13 million (in future dollars, before inflation).

When to use the Retirement Calculator

  • Checking whether your current savings rate is on track for the retirement you want.
  • Estimating how long your savings could last once you start withdrawing.
  • Seeing how retiring a few years later changes the picture.

Common mistakes to avoid

  • Underestimating how long you will live. Planning to age 90 or 95 is safer than age 80.
  • Leaving out inflation and healthcare costs.
  • Relying on a single scenario instead of testing lower returns and higher spending.

Tips

  • Results are in nominal dollars. Inflation reduces what the money can buy in the future.
  • Increase contributions when you get a raise. Small increases early make a big difference.
  • Consider Social Security or pensions as extra income in retirement.

Frequently asked questions

How much do I need to retire?
A common rule is 25 times your yearly spending (the 4 percent rule), but your needs depend on lifestyle, health costs and other income.
What return should I assume?
A moderate figure such as 5 to 7 percent is typical for diversified long-term portfolios. Test lower values too.
What is the 4% rule?
A rule of thumb suggesting you can withdraw about 4% of your savings in the first year of retirement, then adjust for inflation, with a good chance your money lasts about 30 years. It is a guide, not a guarantee.
How much should I save for retirement?
Many planners suggest saving 10% to 15% of your income over your working life, and more if you start late. The right number depends on the lifestyle you want.
