How it is calculated

Interest is calculated monthly at the annual rate ÷ 12. With monthly capitalization it is added to the balance and earns interest itself: final amount = amount × (1 + r)^n, where r is the monthly rate and n the number of months. Without capitalization interest is charged on the principal only and paid out: interest = amount × r × n.

A top-up is added at the end of every month except the last and earns interest from the next month. Interest earned = final amount − the deposit − all top-ups.

The insured amount is the part of the final amount (principal plus interest) within the guarantee limit per depositor and bank; the rest is uninsured. The limit applies to all your accounts in one bank together, so add up your other balances there. Taxes on interest and the bank's own day-count rules are not included.
