How this retirement calculator works

This retirement calculator estimates the value of your savings at retirement by combining your current balance, recurring monthly contributions, and expected annual investment return. It then uses a withdrawal rate to estimate how much income your retirement savings may provide each year and each month.

It also includes an inflation-adjusted estimate so you can compare your projected future balance in today’s dollars. This gives you a more realistic view of what your retirement money may actually be worth when you stop working.

What to enter

  • Your current age and planned retirement age
  • Your current retirement savings balance
  • How much you plan to contribute each month
  • Your expected annual return
  • Your planned withdrawal rate in retirement
  • An estimated inflation rate

What the results mean

  • Savings at Retirement: your projected account balance at retirement
  • Total Contributions: how much you personally added over time
  • Estimated Retirement Income: a simple income estimate based on your withdrawal rate
  • Inflation-Adjusted Value: projected savings shown in today’s purchasing power
  • Growth From Earnings: how much of your final total came from investment growth

Retirement calculator formula

This calculator uses compound growth for your current savings and adds monthly contributions over the years until retirement.

Future Value of Current Savings:
FV = PV × (1 + r / n)nt

Future Value of Monthly Contributions:
FV = PMT × [((1 + r / n)nt - 1) / (r / n)]

Where:

Estimated retirement income is then calculated with:

Annual Income = Retirement Balance × Withdrawal Rate

Tips for using a retirement calculator

Be realistic with returns

A higher return assumption can make your retirement projection look much stronger, but being too optimistic can leave you short later. Many people use a moderate long-term estimate instead of an aggressive one.

Increase contributions over time

Even small increases in monthly contributions can make a big difference over decades because of compound growth. Consider updating your savings rate whenever income rises.

Account for inflation

Inflation affects future purchasing power. A retirement balance that looks large in nominal dollars may buy much less in the future than you expect today.

Review your plan regularly

Retirement projections should be revisited as your age, savings, investment returns, and retirement goals change over time.

Frequently asked questions

How much money do I need to retire?

That depends on your expected spending, retirement age, other income sources, and how long you expect retirement to last. This calculator helps estimate whether your current savings plan is on track.

What withdrawal rate should I use?

Many people use 4% as a starting point for planning, but the right number depends on your retirement timeline, investment mix, and risk tolerance.

Does this calculator include Social Security or pensions?

No. This version focuses only on retirement savings growth and withdrawal estimates. If you want, you can later add a section or another version that includes Social Security, pension income, or other retirement income streams.

Why does inflation matter so much?

Inflation reduces purchasing power over time. A future retirement balance may sound large, but its real value can be significantly lower after adjusting for years of inflation.
