How this loan repayment estimate is calculated

The calculator estimates fixed loan repayments from the amount financed, annual rate estimate, term, repayment frequency, fees and optional regular overpayment entered.

Published by Irish Calculators. Rates, rules and assumptions are maintained against the official sources linked below.

  1. The principal loan amount and optional fees are read from the inputs.
  2. The annual rate is divided into the selected monthly, fortnightly or weekly repayment periods and applied to the reducing balance.
  3. Total repayable and total interest are calculated across the full term.
  4. The regular-overpayment scenario is calculated separately to estimate possible interest and time savings without changing the contractual base repayment.
  5. An advertised APR can include fees and comparison assumptions, so the lender's formal repayment schedule may differ from this rate-based estimate.

Source note: Standard amortising loan formula, with CCPC guidance used for APR, total-cost and early-repayment context. This is an estimate only and not financial advice.

About This Loan Repayment Calculator

This calculator estimates fixed monthly, fortnightly or weekly repayments for personal loans, car finance and other standard reducing-balance borrowing in Ireland. It also shows total repayable, total interest, financed fees and a regular-overpayment comparison.

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.

Rate, APR and fees. This tool applies the annual percentage entered as a fixed rate across the repayment periods. A lender’s APR is a comparison measure that can include interest and set-up costs, so using an APR here gives an estimate rather than reconstructing the lender’s exact schedule. If fees are financed, they increase the balance on which interest is calculated.

Overpayments. The optional regular monthly overpayment is converted to the selected repayment frequency and compared with the base schedule. Before acting, check whether the lender applies extra payments immediately and whether early-repayment fees or penalties apply.

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?
A lender APR is designed to help compare the cost of credit and can reflect interest and certain charges. This calculator applies the annual percentage entered as a rate estimate and lets you add financed fees separately, so it does not recreate every lender APR schedule exactly.
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 monthly, fortnightly, or weekly repayments?
Yes. Choose monthly, fortnightly, or weekly. The same annual rate assumption is converted into the selected number of repayment periods.
How does the regular overpayment comparison work?
The monthly overpayment you enter is converted to the selected repayment frequency and added to the base payment in a separate scenario. It estimates possible interest and time savings, but you should check whether your lender permits overpayments and whether fees apply.
Does this replace a lender quote?
No. It is an estimate for planning only. Always confirm the exact repayment schedule, APR, fees, overpayment rules, and early-settlement terms with the lender.
