Retirement Calculator
Use our free Retirement Calculator to estimate how much you could have saved by the time you retire — adjusted for inflation, withdrawal rate, and your desired monthly income in retirement. Just enter your age, savings, contributions, and expected investment return to see whether you're on track to retire comfortably.
How This Retirement Calculator Helps You Plan Ahead
This tool projects your future retirement savings using compound interest growth and lets you adjust for inflation and your desired monthly retirement income. By including your expected withdrawal rate, you can estimate how much income your savings could safely generate each month without depleting your retirement fund too quickly.
What Each Input Means
- Current Age & Retirement Age: Determines how many years your money has to grow.
- Current Savings: Your starting point for compounding.
- Monthly Contributions: Consistent investing over time is one of the biggest growth factors.
- Expected Annual Return: Long-term stock market averages (after inflation) are often estimated around 6–8%.
- Inflation Rate: Adjusts your projections to “today’s dollars” so you see a realistic buying power estimate.
- Withdrawal Rate: Commonly known as the 4% rule — used to calculate a sustainable yearly income from your savings.
- Desired Monthly Income: If you enter a target income, the calculator will estimate how large your retirement fund needs to be to support that lifestyle.
Planning for Income, Not Just a Big Number
Many people focus on reaching a retirement savings goal, but income planning matters even more. By using your desired monthly income and withdrawal rate, this calculator helps reverse-calculate how big your retirement nest egg needs to be to generate that cash flow.

Frequently Asked Questions
How much money do I need to retire comfortably?
A common guideline is the 4% rule: you need a portfolio large enough that withdrawing 4% per year covers your living expenses. If you need $50,000/year in retirement, you would need approximately $1.25 million saved.
What annual return should I assume for retirement planning?
A conservative assumption is 5–7% per year for a diversified stock and bond portfolio over the long term after accounting for inflation. Historically, the S&P 500 has returned about 10% annually before inflation.
When should I start saving for retirement?
The earlier the better due to compound growth. Starting at age 25 rather than 35 can more than double your retirement balance even with the same monthly contributions, because your money has 10 additional years to compound.
