Retirement Calculator
Project your pension pot to retirement age in today's money, plus the income it gives.
About this tool
Enter your age, target retirement age, current pot, monthly contributions (yours and your employer's), expected return, yearly contribution increase, inflation and a withdrawal rate. The tool projects the pot, converts it to today's purchasing power, estimates monthly income and lists every year in a table.
Reading a retirement projection honestly
Any projection decades out is a curve drawn from assumptions, so the useful habit is to look at the inputs you control โ years and monthly amount โ and treat the return rate as a range rather than a number: run it at 3%, 5% and 7% and plan for the lower one. The conversion to today's money is the part most calculators skip and the part that matters: a pot that sounds enormous in 2056 buys about half as much at 2.5% inflation. The withdrawal rate turns the pot into a monthly figure; the 4% rule is a rough rule from US data, and many planners now suggest 3โ3.5% for long retirements. What is not here, deliberately: tax relief on contributions, state pension, fees, and the risk of a market fall just before retirement โ all of which a regulated adviser or your provider's projection will include. This is arithmetic and general information, not financial advice. Nothing is stored or sent. The compound interest calculator shows the growth of a single lump sum, the savings goal calculator works backwards from a target pot, and the net worth calculator tracks where you stand today.
Frequently asked questions
What return rate should I use?
Long-run diversified portfolios have returned roughly 5โ7% nominal before fees; using 4โ5% builds in a margin. Run several and plan for the cautious one.
Should I include the state pension?
Not in the pot โ add it to the monthly income figure separately, since it is paid as income, not held as capital.
What is the withdrawal rate?
The share of the pot taken as income each year. 4% is the classic rule of thumb; lower is safer for a retirement that may last 30+ years.
Does it include tax?
No. Contributions, growth and withdrawals are taxed differently in every country; check the after-tax version with your provider or an adviser.
