Loan Calculator (Annuity)
Calculate monthly payments, interest overpayment and total credit cost.
How the annuity payment is calculated
The annuity scheme means equal monthly payments over the entire loan term. At first, interest makes up most of the payment; over time, the loan principal takes over.
Payment = Amount × (i × (1+i)^n) ÷ ((1+i)^n − 1), where i is the monthly rate, n is the number of months
The total to be repaid equals the monthly payment multiplied by the number of months. The difference between it and the loan principal is the cost of borrowing.
Loan calculation example
Example 1. A loan of 100,000 UAH for 12 months at 24% per year. Monthly rate i = 24 ÷ 12 = 2% (0.02). Payment = 100,000 × (0.02 × 1.02^12) ÷ (1.02^12 − 1) ≈ 9,455.96 UAH. You repay ≈ 113,471.52 UAH in total, an overpayment of ≈ 13,471.52 UAH.
Example 2. A loan of 50,000 UAH for 6 months at 36% per year: payment ≈ 9,229.88 UAH, total ≈ 55,379.25 UAH, overpayment ≈ 5,379.25 UAH.
The calculator divides the annual rate by 12 and ignores fees and insurance, so the payment in your bank agreement may differ.
Loan FAQ
What is an annuity payment?
Equal monthly payments: you pay the same amount every month, and within it the share of interest gradually decreases while the share of principal grows.
Does the calculator include bank fees?
No, the calculator computes only the advertised annual rate. The real cost may be higher due to fees and insurance — check the effective rate in the loan agreement.
How to reduce loan overpayment?
The most effective ways are partial early repayment, which reduces the principal, and a shorter term. Compare bank offers by the total repayment amount, not the monthly payment.
How is an annuity different from differentiated payments?
With an annuity the payment is the same every month. With a differentiated scheme the principal is split equally and interest is charged on the remaining balance, so payments gradually fall. For 100,000 UAH over 12 months at 24% per year, differentiated payments start at about 10,333 UAH and end at 8,500 UAH, with a total overpayment of about 13,000 UAH versus ≈ 13,472 UAH for an annuity. The first payments are higher, but the overpayment is slightly lower.
How is the overpayment calculated, and what is the effective annual rate?
Overpayment = monthly payment × number of months − loan amount. The effective annual interest rate in your agreement can be higher than the advertised one because it includes fees and other mandatory payments. Compare offers by that rate and by the total cost of the loan.
Can I calculate an interest-free installment plan?
Yes, enter a 0% rate: the payment then equals the amount divided by the number of months. Just check the installment terms for fees and extra payments, which the calculator does not include.
