Retirement Calculator
Project the nest egg your savings could grow into by retirement, and the income it might support. Enter your current age, target retirement age, current savings, monthly contribution, and an expected annual return, then optionally add the monthly income you want to test your readiness. Estimated income uses the 4 percent rule as a planning guide. Every figure is a hypothetical assumption in nominal dollars, not a prediction or advice, and everything stays in your browser.
Enter your age, target retirement age, and expected return to project your nest egg.
How this is worked out
Growth: Your savings compound monthly at the annual return you enter, divided by twelve, with contributions added each month until your retirement age. A constant return is a simplification; real returns vary year to year and can be negative.
The 4 percent rule: Estimated retirement income uses the 4 percent rule, a planning guideline that withdraws about 4 percent of the balance in the first year. It comes from historical US studies and is a guide, not a guarantee that the money will last.
Not modeled: Inflation, taxes, fees, Social Security, and pensions are not included. The nest egg is shown in nominal dollars, so its future spending power would be lower.
Your situation: Every situation is different. The result is a hypothetical projection to help with planning, not advice about how much to save.
Common questions about retirement planning
How much do I need to retire?
It depends on your spending, your other income, and how long retirement lasts. A common starting point is the 4 percent rule, which suggests a balance roughly 25 times your annual spending. This tool projects a balance and the income it might support, as an estimate only.
What is the 4 percent rule?
It is a planning guideline that withdrawing about 4 percent of a portfolio in the first year of retirement, then adjusting for inflation, has historically lasted around 30 years in US studies. It is a guide, not a guarantee, and some planners use a lower rate for longer retirements.
How is my nest egg projected?
The tool compounds your current savings and monthly contributions each month at the return you enter until your retirement age. The result is a hypothetical figure in nominal dollars based on your assumptions, not a prediction.
Does this include inflation, taxes, and Social Security?
No. The projection leaves out inflation, taxes, fees, Social Security, and pensions, so it is a simplified estimate. Real spending power and after-tax income would differ.
What return should I assume?
There is no correct figure. Long run averages are sometimes used as a reference, but returns vary every year and are not guaranteed. Testing a more conservative rate shows how sensitive the result is to that assumption.
Is this calculator financial advice?
No. It is an educational estimate based on the numbers you provide, and it is not financial advice. A licensed financial planner can help build a plan for your situation.
These results are estimates, not predictions. They are based on the inputs you provide and assumed rates of return, which are not guaranteed. Real markets rise and fall every year. For educational purposes only, not financial advice.
