Target 500,000 in 25 years, current pot 50,000, 6% expected return: required monthly about 412. Current pot grows to 215,000 alone, leaving 285,000 gap to fill with new contributions. Larger current pot or higher return dramatically reduces required savings.
A worked example
Try the defaults: retirement target of 500,000, years to retirement of 25, current pot of 50,000, expected return of 6%. The tool returns 411.85. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Retirement Target, Years to Retirement, Current Pot, and Expected Return. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.
The formula behind this
Future value of current pot projected; gap filled by monthly contributions. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
How to use this beyond the first run
Re-run the calculation once a year. Life changes — pay rises, new expenses, interest-rate shifts — and the figure that looked right 12 months ago often isn't today. Annual recalibration keeps the plan honest.
What this doesn't capture
The calculation assumes a steady savings rate and a stable interest rate. Real saving journeys include emergencies, windfalls, and rate changes — especially in easy-access products. The figure is a direction of travel, not a guarantee.
Retirement fund target produces a monthly contribution based on the inputs provided.
