Retirement Calculator
Check whether your retirement saving is on track. Enter your age, the age you want to retire, current savings, monthly contributions, expected return and inflation, the yearly income you want in today’s money and other income such as a state pension. The calculator projects your savings, converts them to today’s money, compares them with the nest egg needed at your chosen withdrawal rate and shows the extra monthly saving needed to close any gap.

Retirement Calculator FAQ
What is a safe withdrawal rate?
The share of savings you withdraw each year. 4% is a widely quoted starting point from historical studies, not a guarantee.
Which return should I assume?
Use a conservative, after-fee figure. Long-term balanced portfolios are often modelled at 4–6% before inflation.
Is this financial advice?
No. It is a projection with constant assumptions; real markets vary.
Why use today’s money?
Because a million in thirty years buys much less than a million today.
What is the 4% rule?
A rule of thumb that withdrawing about 4% of a portfolio in the first year, then adjusting for inflation, has historically lasted around 30 years. It is not a guarantee.
Reading the projection
Retirement planning compares two numbers: the savings you are likely to have and the savings you need to fund your desired income. Both depend on assumptions, so the gap is more useful as a direction than as an exact figure.
Small changes compound over decades: a slightly higher contribution, a year or two of extra work or lower fees can close a gap that looks large today.
Inflation changes what retirement income means. 30,000 a year in today’s money is about 62,800 a year in 25 years at 3% inflation. A common rule of thumb, the 4% rule, suggests a pot of about 25 times the yearly income you need – 750,000 for 30,000 a year in today’s money.
Returns, inflation, pensions and tax are all assumptions, and small changes over decades make large differences. Use the result to see whether you are roughly on track, and get personal financial advice before making major decisions.
