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.

Frequently Asked Questions

Target too high?
Common. Lower target, work longer, or save more aggressively. Compromise between these three usually needed.
Employer match boost?
Employer match counts toward contributions. Subtract from required monthly before planning personal savings.
What if already behind?
Catch-up contributions in final decade help but can't fully replace missed early compounding. Earlier is always better.
Market crash concerns?
Short-term volatility rarely derails long plans. 3-5 year downturn near retirement is bigger concern — de-risk approaching target date.
