Guide
How the projection works
The calculator grows your current savings and each monthly contribution at the expected return, month by month, until your retirement age. It then applies a withdrawal rate, 4% by default, to estimate a sustainable yearly income. The 4% rule comes from research showing that a balanced portfolio could historically support withdrawals of about 4% of the starting balance, adjusted for inflation, for around thirty years.
Worked example
A 30-year-old with 20,000 saved who adds 500 a month and earns 7% a year will have roughly 1,130,000 by age 65. At a 4% withdrawal rate that supports about 45,200 a year. If the goal is 60,000 a year, the target nest egg is 1,500,000, so the saver would need to contribute more, work a few years longer, or aim for a higher return with more risk.
Choosing realistic inputs
Long-term stock market returns have averaged around 6–8% a year before inflation in many developed markets, while bonds and deposits earn less. Using a return that is already adjusted for inflation, such as 4–5%, gives an answer in today's money, which is easier to compare with your current spending. Most people need 60–80% of their pre-retirement income, depending on housing costs and health care.
Ways to close a gap
Increase contributions each time your salary rises, capture any employer match, which is free money, reduce investment fees, delay retirement by a couple of years, or plan part-time work in early retirement. Public pensions such as social security or state pensions reduce how much your own savings must provide; subtract them from the desired income before entering it.
Privacy and accuracy
Everything is computed on your device and no data is stored. The result is an educational estimate, not financial advice; returns, inflation, taxes and pension rules differ by country and change over time, so review the plan every year.

Frequently asked questions
How much do I need to retire?
A simple estimate is 25 times the yearly income you want from savings, which corresponds to a 4% withdrawal rate.
What is the 4% rule?
It suggests withdrawing 4% of your savings in the first year of retirement and adjusting for inflation afterwards, which historically lasted about thirty years in most cases.
Should I include my pension?
Subtract expected pensions from your desired income first, then enter the remainder as the income your savings must provide.
What return should I use?
For a diversified portfolio many planners use 5–7% before inflation, or 3–5% after inflation. Test several values.
Is this tax-aware?
No. Taxes on contributions and withdrawals vary by country and account type, so treat the result as a pre-tax figure. You can use this retirement calculator free, with no sign-up.
