Retirement planner

How to use this tool

1. Enter your age now and the age you want to retire.
2. Add your savings so far, how much you save each month, and the return you expect.
3. Enter the monthly income you want in retirement, in today's money, and a withdrawal rate.
4. Read whether you are on track. If there is a shortfall, the planner shows the monthly saving that closes it. Download the yearly projection as a CSV.

How it works

The planner grows your savings and monthly contributions at the expected return until you retire. It then works out the nest egg needed to pay your target income: yearly income divided by the withdrawal rate. That target is raised by inflation so it matches the buying power you want at the retirement date.

Savings = S × (1 + r)^t + C × ((1 + i)ⁿ − 1) ÷ i
Nest egg needed = yearly income ÷ withdrawal rate × (1 + inflation)^t

Good to know

The 4% rule comes from US research on portfolios of stocks and bonds that lasted about 30 years. If you retire early or expect a long retirement, a lower rate such as 3 to 3.5% is more cautious. A higher return assumption makes the plan look easier, so test a pessimistic return too.

The projection ignores tax, pensions, social security and one-off costs. Treat it as a way to compare plans, for example saving 200 more a month or retiring two years later. The currency selector changes only the symbol and number format and no exchange rates are used.
