Deposit Account Calculator

Calculate the Interest you will earn with our Savings Account Interest Calculator

With so many great options on offer, it can be difficult choosing the account which best suits your savings requirements. But with this simple Savings Calculator, you can easily compare KBC range of terms and rates of return for each of the accounts on offer.

All accounts are subject to a minimum balance of €3,000 (£2,000).

Interest is subject to Deposit Interest Retention Tax (DIRT) where applicable. Terms & Conditions apply.

What is DIRT? This is a tax paid on any interest earned in respect of a deposit with a financial institution (standard rate of DIRT is currently 41%, but is subject to change. Check out for current rate). The Bank deducts DIRT from the interest it pays to customers and forwards it to the Revenue Commissioners. There are certain exceptions where customers may be exempt from paying DIRT. Check out for more information.

Terms & Conditions Apply.

AER means Annual Equivalent Rate and shows what the interest rate would be if the interest was compounded and paid each year (instead of monthly or over any other period). Interest for Euro accounts is calculated on a 360 day basis but paid on a 365 day basis. Interest on Sterling accounts is calculated and paid on a 365 day basis. In the case of Fixed Term Accounts interest is paid at the end of the term or as specified by the account Terms & Conditions. Unless the Bank receives instruction(s) from you on or before the maturity date, the full balance in the account will be reinvested in a similar fixed term product at the prevailing interest rate for that product on that date. If on the maturity date there is no similar fixed term product available, the full balance in the account will be reinvested in our Standard Demand Deposit account earning the then prevailing Standard Demand Deposit Account interest rate.Interest is paid by Electronic Funds Transfer (16 Days after receipt of cleared funds by KBC Bank Ireland). In the case of the Top-Up Deposit Account, there is one lodgement and one withdrawal of up to 25% of the original amount deposited during the term permitted. No further lodgements or withdrawals are permitted from the account during the term. In the case of Demand Deposit Accounts interest is added twice-yearly. In the case of a Smart Access Demand Account interest is added annually in December. Gross interest quoted is correct as at 11th March 2015 and subject to availability. Sterling rates are correct as at 11th March 2015 and subject to availability. All accounts are subject to a minimum of €3,000 (£2,000)

**Where applicable, if you make a withdrawal from the account before the end of the term, the amount of interest earned will be less than if the deposit had been left intact for the full duration of the term.
