What this means

This compounds the starting amount and treats regular contributions as payments into each compounding period.

Formula used

A = P(1 + r/n)^(nt), with regular contributions added per compounding period.

Worked example

Starting with £5,000 and adding £250/month for 20 years at 6% monthly compounding gives about £132,061.22.

Common questions

Can I use this internationally?
Yes. Currency selectors are display-only unless a tool explicitly says otherwise; no currency conversion is performed.

How exact is the result?
It follows the published Technofatty formula for this tool, but real life can add fees, rules, timing quirks, and context.

Plain-English summary

The useful number is not just the final balance; it is how much came from contributions versus growth.

This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
