Free Retirement Savings Calculator
Project your retirement balance and the income it could support in today's money.
Your current savings and monthly contributions, which can rise by a set percentage each year, are grown monthly at the expected return until retirement age. The balance is also deflated by inflation to give today's money, and the withdrawal rate is applied to that to estimate yearly and monthly income.
How to use the Retirement Savings Calculator
- Enter your starting amount, regular contribution, expected return and time period.
- Read the end value and the split between money you put in and growth.
- Try a lower return as well as a higher one, because real markets are uneven.
About the Retirement Savings Calculator
Project your retirement balance and the income it could support in today's money.
Time and consistency do most of the work in saving and investing. Running the numbers shows how small changes in rate, term or contribution add up.

Tips for better results
Focus on the inflation-adjusted figures, since the nominal balance overstates future buying power. Test lower returns to see how sensitive the plan is, and raise contributions with each pay rise.
Treat the result as an illustration, not a promise. Returns vary year to year.
Fees and inflation reduce real growth, so consider both when planning.

Frequently asked questions
What is the withdrawal rate?
It is the share of the retirement balance you take out each year; 4 percent is a common rule of thumb, not a guarantee. A lower rate is safer for a long retirement.
Does this include pensions or Social Security?
No. It only projects the savings you enter, so add other income sources separately.
Is the retirement savings calculator free?
Yes. It is free to use with no signup, no watermark and no usage limits.
Is my data private?
Yes. Your inputs are processed in your browser and saved only in its local storage. They are not uploaded to our servers.
Does it work on mobile?
Yes. Zapxa works on phones, tablets and desktops. Use the print button or download a PDF to keep a copy.
