Assumptions: ISA returns and loan interest are compounded monthly. Repayments are applied monthly (1/12 of annual amount). Salary-linked repayments are recalculated each year with salary growth. The loan is written off after the specified term — any remaining balance at that point disappears. This is a simplified model; actual student loan interest may vary (e.g. RPI-linked). ISA returns are not guaranteed. This is not financial advice.
