In detail: Compound Interest Calculator for £1,000 over 10 Years
£1,000 is a meaningful starting amount: over 10 years, even a modest 5% real return turns it into £1,628.89, and a stock-market-like 7% turns it into £1,967.15. The difference between those two rates — about £338.26 — is entirely the power of a slightly higher compounding base rate over 10 years.
Over a 10-year window, compounding hasn't yet done its heaviest lifting — the bulk of your end balance is still the original contribution. If you can extend the horizon to 20+ years (by starting earlier or leaving it untouched), the same £1,000 at 7% grows to roughly £3,869.68 at 20 years and £7,612.26 at 30.
Adding monthly contributions to the pot accelerates this substantially. Even £100/month on top of £1,000 at 5% pushes the 10-year total up to roughly £16,628.89, because each contribution gets its own compounding tail.
