Retirement Savings Calculator
Project your nest egg and monthly retirement income.
Find out if your retirement savings are on track by projecting your future nest egg based on your current savings, contributions, and investment return.
Planning for Retirement
The 4% Rule
The 4% rule says you can withdraw 4% of your savings in the first year of retirement, then adjust for inflation each year — and historically your money lasts 30+ years. A nest egg of 1 million USD generates about 40,000 USD per year. To retire at 65 with 50,000 USD per year in income, target at least 1.25 million USD saved.
Inflation Eats Purchasing Power
At 3% annual inflation, prices double roughly every 24 years. A 1 million USD nest egg today would only have the buying power of about 500,000 USD in 24 years. That's why this calculator shows both the nominal projected value and the inflation-adjusted equivalent so you can plan in today's dollars.
Start Early, Contribute Consistently
Time in the market is the biggest lever in retirement savings. Starting at 25 vs 35 with the same monthly contribution can result in double the nest egg by retirement, purely because of compound growth. Even small increases in monthly contributions early in your career have an outsized impact.

FV = PV×(1+r)^n + PMT×[(1+r)^n − 1]/r Frequently Asked Questions
How much do I need to retire comfortably?
A common target is 25 times your annual expenses, based on the 4% withdrawal rule. If you plan to spend 50,000 USD per year in retirement, aim for 1.25 million USD saved. Your specific number depends on your lifestyle, health, and other income sources like Social Security.
What annual return should I use?
Historically, a diversified stock portfolio has returned about 7% per year after inflation. For a blended portfolio of stocks and bonds, 5–7% is a reasonable assumption before inflation. Be conservative — it's better to be pleasantly surprised than to run short.
Does the calculator account for Social Security?
No — this calculator projects savings only. Social Security income should be added on top of your nest egg withdrawals when planning your full retirement income. You can estimate your Social Security benefit at ssa.gov.
What is inflation-adjusted value?
It's your projected nest egg expressed in today's dollars. If you retire in 30 years with 1 million USD but inflation averaged 3%, that 1 million only buys what about 412,000 USD buys today. The inflation-adjusted figure helps you plan in terms you can relate to now.
How does monthly contribution affect the final amount?
Monthly contributions compound over time just like your existing savings. Even an extra 100 USD per month at age 30 can add over 100,000 USD to your nest egg by age 65 (at 7% return). The earlier you increase contributions, the greater the compounding effect.
What is the formula for Retirement Savings Calculator?
FV = PV × (1 + r)^n + PMT × [(1 + r)^n − 1] / r, where FV is the future value (nest egg), PV is your current savings, r is the monthly interest rate (annual rate divided by 12), n is the total number of months until retirement, and PMT is the monthly contribution.
