How interest is calculated - Postgraduate Loan

Find out how interest is calculated and applied if you have a Postgraduate Loan from England or Wales, as well as previous interest rates.

If you had postgraduate student finance from Northern Ireland, you’ll repay under Plan 1.

If you had postgraduate student finance from Scotland, you’ll repay under Plan 4.

When interest is applied

You’re charged interest from the day we make your first payment to you or to your university or college until your loan has been repaid in full or cancelled. Interest is added to your balance each month.

Annual interest rate changes

The interest rate is usually set on 1 September each year, based on the Retail Price Index of the previous March. The interest rate charged is normally the Retail Price Index plus 3%.

However, during some periods we may apply an interest cap to ensure you’re not being charged a higher interest rate than the average found in the commercial market.

What is the Retail Price Index?

It’s a measure of inflation, which measures changes to the cost of living in the UK.

What is the interest rate cap?

The Department for Education monitors interest rates set by commercial banks using monthly data provided by the Bank of England.

If the average commercial interest rate is lower than the interest rate you’re being charged on your Postgraduate Loan, we’ll apply a temporary interest rate cap, so you’re not disadvantaged. The interest rate will be reviewed after 3 months and changed if necessary.

The current interest rate is capped at 6.9%.7.1%.

Previous interest rates

The rates in the table apply to the Postgraduate Loan only.
