Two modes
- Loan - you know the amount you are borrowing.
- Mortgage - you know the property price and how much of your own money goes in. The bank lends the difference, and that is what interest is charged on.
Switching modes swaps in a typical rate and term for that kind of borrowing: a mortgage costs noticeably less than a consumer loan and runs much longer.
What each field means
- Loan amount, or property price and down payment - depending on the mode.
- Term - months for a loan, years for a mortgage.
- Annual rate - the nominal one from the contract, before fees.
- Annuity or classic schedule - how the payments are spread over time.
- One-time fee - a percentage of the amount the bank keeps when the loan is issued.
- Monthly fee - a percentage of the loan charged every month. Often insurance or a servicing charge.
An example
A 100 000 ₴ loan over 36 months at 36.91 % a year (the average rate on new consumer loans, NBU data for August 2026), annuity, no fees - exactly what the calculator shows on opening:
- monthly payment: 4 632 ₴
- total paid: 166 765 ₴
- overpayment: 66 765 ₴
- true rate (APR): 43.84 %
Now add typical fees - 1 % one-time and 0.5 % monthly: the total becomes 185 765 ₴, of which 19 000 ₴ is fees alone, and the APR jumps to 57.48 %. The contract rate has not moved: it is still 36.91 %.
Why APR is higher than the advertised rate
The true rate counts more than the interest: it includes the fees and when exactly the money leaves your hands. Even with no fees at all, the APR sits above the nominal rate, because interest accrues monthly and those accruals compound over the year. The higher the rate, the wider the gap - at 36.91 % it is already 43.84 %.
APR is the number to compare offers on. A 36.91 % rate with a 0.5 % monthly fee works out dearer than an honest 45 % with no fees.
Annuity or classic
Annuity means the same payment every month. Easy to budget for, but early on almost all of it goes to interest and the principal shrinks slowly.
Classic repays the principal in equal parts, so the payment falls month by month. On the same terms the first payment is 5 854 ₴ and the last is 2 863 ₴, with a total overpayment of 56 903 ₴ instead of 66 765 ₴.
The classic schedule is cheaper but demands a higher income up front. Which is why banks tend to offer the annuity one.
A mortgage example
A 2 000 000 ₴ property, 400 000 ₴ down, over 20 years at 11.29 % - the average rate on new house-purchase loans, NBU data for August 2026, state programmes such as «єОселя» included:
- payment: 16 832 ₴ a month
- total paid: 4 039 667 ₴
- overpayment: 2 439 667 ₴, more than the flat itself costs
The calculator flags a down payment below 20 % of the price: banks rarely approve a mortgage under that, and the rate is usually higher when they do.
The amortization schedule
The table under the calculator lists every payment: how much went to the principal, how much to interest and fees, and what debt is left. On long terms it switches to a yearly view automatically - 240 rows are not worth reading - and the toggle is always there.
What the calculator leaves out
It assumes the rate holds for the whole term and that you pay exactly on schedule. Not included: property and life insurance, notary and valuation costs on a mortgage, late-payment penalties, and the savings from paying the loan off early.
