This calculator works out how much of each pay goes to your student loan in the 2026 to 2027 tax year, following GOV.UK's repayment guide and HMRC's rates and thresholds for employers. It covers Plans 1, 2, 4 and 5 and the Postgraduate Loan, alone or together.
The rule. Each plan has a yearly threshold, shared out over your pays: Plan 2's £29,385 is £2,448.75 a month or £565.09 a week. You repay 9% of what you earn above it in that pay, rounded down to the whole pound. A Postgraduate Loan takes 6% above £1,750 a month.
More than one plan. With Plan 1 and Plan 2 you still make one repayment, 9% over the lower Plan 1 threshold. The lower plan takes at most 9% of the gap between the thresholds, £18 a month, and the rest goes to the other loan. A Postgraduate Loan is always repaid on top, so £2,500 a month with Plan 2 and a Postgraduate Loan repays £45 plus £4.

For the 2026-27 tax year the yearly thresholds are £26,900 for Plan 1, £29,385 for Plan 2, £33,795 for Plan 4, £25,000 for Plan 5 and £21,000 for a Postgraduate Loan. Payroll uses a monthly or weekly share of each, such as £2,448 a month for Plan 2.
You repay 9% of your pay above your plan's monthly threshold, rounded down to the pound. On Plan 2 with £3,000 a month, 9% of the £551.25 above £2,448.75 is £49.61, so £49 is taken, or £588 over a year. The amount you owe does not change it.
A Postgraduate Loan is repaid at 6% of pay over £21,000 a year, on top of any Plan 1, 2, 4 or 5 repayment. On £2,500 a month with Plan 2 as well, GOV.UK shows £45 for the Postgraduate Loan plus £4 for Plan 2, a total of £49.
HMRC works out the repayment on your whole year's income through your Self Assessment tax return. Choose the year as the pay period: on Plan 1, £42,000 of combined income gives 9% of the £15,100 above £26,900, which is £1,359 for the year, less anything already repaid through a salary.
