How loan balance amortizes over time
In the early years of a fixed education loan, a significant portion of each monthly payment goes toward interest, with only a small fraction reducing principal. As the balance decreases, interest charges shrink, accelerating principal reduction.
Worked example
On a £25,000 loan at 8.5% over 10 years (120 payments of £310.01), after 24 monthly payments (2 years), your remaining principal balance is approximately £21,780.
You have paid £7,440 in total instalments, consisting of £3,220 in principal reduction and £4,220 in interest.

Does making extra payments reduce the balance faster?
Yes, extra payments go directly toward reducing the principal, which lowers future interest and shortens your payoff schedule.
