How is the monthly repayment calculated?

It uses the standard amortising-loan formula. The fixed monthly payment is the loan amount times the monthly rate, divided by one minus (1 plus the monthly rate) to the power of minus the number of months. Each payment covers that month's interest first, and the rest reduces the balance.

What APR is typical for Irish personal loans?

Irish personal loan APRs commonly fall between about 6 and 17 percent, depending on the lender, the amount and your credit profile. Credit unions and banks often sit at the lower to middle of that range for larger or secured loans, while smaller unsecured loans cost more.

What is the difference between APR and the interest rate?

The nominal interest rate is just the cost of borrowing, while the APR also reflects how often interest is charged and certain fees, giving a truer annual cost. For a simple personal loan with no fees the two are very close; this calculator treats the rate you enter as the APR used to derive the monthly rate.

Can I pay the loan off early?

Most Irish personal loans, especially variable-rate ones, allow early repayment without penalty, which saves interest because you stop paying it on the cleared balance. Fixed-rate loans may carry a small breakage cost. Paying extra each month shortens the term and cuts total interest.

Does this include insurance or fees?

No. It models principal and interest only. Optional payment-protection insurance, arrangement fees or late charges are extra and are not included, so always compare the lender's total cost of credit and the official APR before borrowing.

The Ireland Personal Loan calculator turns a loan amount, an interest rate and a term into a clear monthly repayment, the total interest you will pay, and a schedule showing how the balance shrinks. It uses the typical APR range Irish banks and credit unions quote, so you can compare offers and see exactly what a loan costs before you commit.

How it works

A personal loan is an amortising loan: you pay the same amount every month, but the split between interest and principal changes. The fixed monthly repayment is:

M = P x r / (1 - (1 + r)^(-n))

where P is the amount borrowed, r is the monthly rate (APR / 12 / 100) and n is the number of monthly payments. Each month the lender charges interest of balance x r, the rest of your payment reduces the principal, and the cycle repeats until the balance reaches zero.

Total interest = (monthly repayment x number of payments) − amount borrowed.

Early in the term most of each payment is interest; later, most of it pays down principal — which is why overpaying early saves the most.

Tips and notes

The result depends heavily on the APR, so it is worth shopping between banks and credit unions — Irish rates commonly run from about 6 to 17 percent. A shorter term means a higher monthly payment but much less total interest. This estimate covers principal and interest only; arrangement fees and optional payment-protection insurance are extra, so always compare each lender’s official APR and total cost of credit, and check whether early repayment is penalty-free.
