This is a guide figure, not financial advice. The exact amount comes from your bank or the relevant authority.
Enter your starting deposit, monthly top-up, annual interest rate and number of years. The calculator uses compound interest, so interest that's been added earns interest of its own. You see how much you paid in, what the interest brought and the final balance, with a year-by-year breakdown. For euro savings in Serbia, enter 15% tax.
How it works
Compound interest on a single deposit: A = P · (1 + r/m)m·n, where P is the deposit, r the annual rate, m how many times a year interest is added and n the number of years.
The calculator works month by month. Interest is charged on the balance and added monthly, quarterly or yearly, and the monthly top-up goes in at the end of each month. If you enter a tax rate, it's taken off every time interest is added.
Banks also quote an effective rate (EKS in Serbia, AER in the UK) that already allows for how often interest is added. That's the figure to compare.
Worked example
Dinar savings: 200,000 dinars to start, 10,000 a month, 4% a year with interest added monthly, for 5 years. You pay in 800,000 dinars, interest adds 107,189 and you end up with 907,189.10 dinars. No tax is due.
Euro savings: €3,000 plus €100 a month at 3% for 5 years. Before tax the interest would be €949.52. After 15% tax you keep €799.55, for a balance of €9,799.55.
Questions people ask
Is interest on savings taxed in Serbia?
Interest on dinar savings held by individuals is tax-free. Interest on foreign-currency savings, such as euros, is taxed at 15%, and the bank normally deducts it for you. Check your bank's terms and the current Personal Income Tax Act for your own case.
How do I work out interest on a fixed-term deposit?
Set the monthly top-up to 0, enter the term in years (6 months is 0.5) and choose how often interest is added, as in your contract. A one-year deposit usually pays interest once, at the end.
What is compound interest?
Interest on interest. Each time interest is added it becomes part of the balance and earns interest itself in the next period. The longer the term, the bigger the gap compared with simple interest.
Is monthly or yearly interest better?
At the same rate, monthly pays slightly more. In the dinar example above the difference is about 1,984 dinars over five years.
