This is a guide figure, not financial advice. The exact amount comes from your bank or the relevant authority.
Enter the loan amount, the nominal interest rate and the term, and the calculator shows the monthly payment, total interest and a full repayment schedule. It works for cash loans, mortgages and car loans, in dinars or euros. You can compare equal monthly payments with equal capital repayments, where the instalment shrinks each month.
How it works
The monthly rate is the annual nominal rate divided by 12. An equal monthly payment uses the formula R = P · i / (1 − (1 + i)−n), where P is the amount borrowed, i the monthly rate and n the number of payments. Each month interest is charged on the balance still owed and the rest of the payment goes off the capital. That's why, in the early years of a mortgage, most of each payment is interest.
With equal capital repayments the loan is divided into n equal slices and interest is added on whatever is left, so the payment falls over time.
Banks also charge an arrangement fee, insurance and account fees. All of that is rolled into the effective interest rate, called EKS in Serbian offers (the APR elsewhere). Compare offers on that figure, not the nominal rate.
Worked example
A cash loan of 600,000 dinars over 48 months at a nominal 9.95%: the payment is 15,203.15 dinars a month and total interest comes to about 129,751 dinars. If another bank offers 11.5%, the payment rises to 15,653.41. A gap of 450 dinars a month looks small, but over four years it adds up to about 21,600.
The same loan with equal capital repayments starts at 17,475.00 dinars and ends at 12,603.65, with 121,887.50 in interest.
A €60,000 mortgage over 25 years at 4.5% costs about €333.50 a month. Interest over the whole term is roughly €40,050.
Questions people ask
What's the difference between the nominal rate and the APR?
The nominal rate is what interest on the debt is worked out from. The APR, or EKS in Serbia, shows the full cost of the loan including fees and insurance. Use it when comparing banks.
Which works out cheaper: equal payments or equal capital repayments?
Equal capital repayments cost less interest overall: about 7,860 dinars less in the example above. The catch is a first payment roughly 2,270 dinars higher. Equal payments are easier to budget for.
Can I work out a loan in euros?
Yes. Enter the amount in euros and the payment comes out in euros. Many Serbian loans are indexed to the euro but paid in dinars, so the dinar amount moves with the exchange rate on the day you pay.
What if the interest rate is variable?
Then the payment follows a reference rate such as EURIBOR or BELIBOR. The calculator uses one rate for the whole term, so enter today's rate and then try one or two points higher to see how far the payment could jump.
Why is the bank's figure slightly different?
Banks use the actual dates of drawdown and payment, and some add insurance to the instalment. A difference of a few dozen dinars isn't a mistake.
