When to use this calculator
- When you need a fast estimate before making a bigger decision.
- When you want to compare a few scenarios using the same assumptions.
- When you need a clearer starting point before using a detailed quote or formal document.
- When you want to sanity-check a figure you have seen elsewhere.
A worked example

How to read your results
Monthly Payment
The regular payment produced by this scenario. Change the term or rate to see how the debit moves.
Method & assumptions
This calculator estimates a fixed-term amortising student loan: monthly payment, total repaid and interest from the balance, APR and term you enter. That is the repayment shape used by many private or overseas loans.
It is not the UK Student Loans Company model. UK Plan 1, 2, 4 and 5 repay 9% of income above an HMRC threshold and can be written off after a set term. Use the UK Student Loan Calculator for those plans, and the overpayment tool if you want to model extra payments on an SLC balance.
Common mistakes
- Using optimistic assumptions without testing a more cautious scenario.
- Comparing outputs from different tools without checking that the inputs match.
- Treating the result as a final quote instead of a planning estimate.
- Rounding inputs too aggressively.
What to do next
- Try at least one more scenario so you can compare a realistic range.
- Use the related calculators below to cross-check the decision from another angle.
- Write down the key outputs from your best scenarios before you decide.
- If the result surprises you, change one input at a time to isolate the driver.
