Student Loan Repayment Calculator – FAQs
What does this calculator estimate?
It estimates your current mandatory student loan deduction, compares it with your chosen interest rate, and projects whether your loan is more likely to be repaid in full or written off first.
Does it include pension contributions and salary sacrifice?
Yes. Existing pension contributions and extra salary sacrifice can reduce the income used for PAYE student loan deductions, so both are included in the estimate.
Does this use real future interest rates?
No. The projection assumes the same interest rate you enter remains constant. In real life, student loan interest rates and repayment thresholds can change.
Can I include a postgraduate loan too?
Yes. You can include one undergraduate plan plus an optional postgraduate loan, and the calculator will apply both deductions in parallel.
Is the payoff or write-off date guaranteed?
No. It is an estimate based on your assumptions for salary, pension, interest and salary growth. Actual outcomes can differ.
