Open the Loan affordability from payment calculatorWhat to prepare
- Find the relevant statement, payslip or transaction record rather than estimating from a bank balance.
- Identify the tax year, transaction date and whether each amount is gross, net, annual or monthly.
- Separate known facts from assumed rates and check eligibility against the linked official sources.
Understand the inputs
The calculation method
Discount equal monthly payments at the entered nominal rate over the chosen term.
Worked example
Illustrative inputs and their result.
Example inputs

- 7
- Loan term (months)
- 60
Calculated example result
- Maximum Principal
- €17,675.70
- Total Interest
- €3,324.30
How to interpret the result
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.
Compare the same income or transaction under one changed assumption at a time. 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.
Assumptions and sources
Mathematical payment capacity; lender affordability and fees need separate assessment.
