How this works
Each plan year you pay a fixed share of income above your plan's threshold, whatever your balance is. Whatever's left is wiped a set number of years after the April you first started repaying, however big it still is. If the compulsory repayments would clear the balance before that date, interest genuinely costs you and paying it off faster can save money. If they wouldn't, paying extra mostly hands the government money that would otherwise have been cancelled for free.
