Graduates in the UK are facing a “motherhood penalty” on their student finance, with interest continuing to build on loans even while they are on maternity leave and unable to make repayments. In one instance, a graduate reported that their total debt had reached £70,000 despite only borrowing £42,000 originally.
The issue has been brought to the floor of the House of Commons by Chichester MP Jess Brown-Fuller. The MP raised the specific case of a local constituent whose student loan balance increased significantly beyond the original sum while she was away from work to care for her child.
Under the current system, interest is added to student loans every month from the day the first payment is made to the student until the loan is paid off in full or cancelled. While compulsory repayments stop if a borrower’s income falls below the designated threshold—which commonly happens during career breaks or maternity leave—the interest continues to accrue on the outstanding balance.
The ‘Motherhood Penalty’ explained
For many parents, the period of maternity leave creates a gap where no progress is made on clearing the debt, while the total amount owed grows due to interest. This has led to calls for reform, with critics arguing that the system unfairly penalises women and those taking time out for family responsibilities.
The financial gap is underscored by the current rates of Statutory Maternity Pay. For the 2026/27 tax year, this is set at £194.32 per week. This figure remains below the repayment threshold for student loan plans. While the system protects the monthly take-home pay of those on maternity leave by pausing compulsory repayments when income falls below the threshold, it does nothing to prevent the total debt from escalating in the background as interest continues to accrue.
Interest rate changes and caps
The government has recently confirmed new measures regarding student loan interest. From 1 September 2026, interest rates for Plan 2 and Plan 3 (postgraduate) loans will be capped at 6%. This follows a period where high inflation led to concerns that interest rates could reach double figures without intervention.
The Retail Prices Index (RPI), which is used to set student loan interest rates, has been confirmed at 4.1% for the 2026/27 academic year. Further details on these thresholds and the application of interest can be found via official government guidance on GOV.UK.
Despite the upcoming 6% cap, the fundamental mechanism remains: interest is charged on the total balance regardless of the borrower’s current ability to pay. For those with high original balances, like the £42,000 cited in Parliament, a 6% interest rate can still add thousands of pounds to the debt annually, potentially outpacing the repayments made once the borrower returns to the workforce.
The Department for Education maintains that the system is designed to be fair by ensuring that those who earn more contribute more, and that no one is required to make repayments they cannot afford. However, the case raised by Chichester’s MP highlights a growing concern that for a generation of graduates, the total debt may become insurmountable due to the compound interest applied during life events such as parenthood.
