Open the Loan affordability from payment calculatorWhat to prepare
- Have the figures for affordable monthly payment (€), annual interest rate (%) and loan term (months) ready, from a dated document, with the period (annual, monthly or per transaction) that each input expects.
- Note the date of the transaction, since this model has no year selector and fixed rates may have changed.
- Separate known facts from assumed rates before relying on the headline result.

How to interpret the result
Mathematical payment capacity; lender affordability and fees need separate assessment. Distinguish a tax saving, a tax bill, cash received and money remaining: they are not interchangeable. An estimate does not establish eligibility, filing compliance or when a refund will be paid.
Change one input of loan affordability from payment at a time and record the result; keep a record of the year, date and assumptions so a change in the result can be explained.
Common mistakes to avoid
- Do not mix tax years or apply a newly announced measure to an earlier transaction.
- Avoid counting an allowance, credit, contribution or loss twice.
- Check exclusions and personal circumstances before relying on the headline result.
