About This Loan Repayment Calculator

This calculator estimates fixed monthly or weekly repayments for personal loans, car finance, and other standard fixed-rate borrowing in Ireland. It also shows the total repayable amount, total interest, and the impact of financed fees.

How repayments are calculated. Repayments use the standard amortisation formula. Each repayment covers the period’s interest first, then reduces the outstanding principal. That means the balance falls faster later in the term.

P × r ÷ (1 − (1 + r)−n)

Where P is the total financed amount, r is the periodic interest rate, and n is the number of repayment periods.

APR and fees. This tool assumes a fixed rate for the full term. If the lender adds fees to the borrowing instead of charging them upfront, those fees increase the amount on which interest is paid.

This calculator is for illustration only and does not replace a formal lender quote. Always confirm repayment schedules, APR assumptions, and fee treatment before signing a credit agreement.

Frequently Asked Questions

Does APR include fees?
APR often reflects the cost of credit, but this calculator also lets you add extra fees directly to the financed amount for a more practical estimate.
Why does a longer term reduce the payment but increase total cost?
Spreading repayments over more periods lowers each payment but increases the total interest paid over time.
Can I use this for weekly repayments?
Yes. This calculator supports both monthly and weekly repayment views.
Does this replace a lender quote?
No. It is an estimate for planning only. Always confirm exact repayment figures with the lender.
