How this calculator helps
What the calculator is for
The loan calculator gives a quick estimate of the monthly payment for a consumer loan or any other annuity-style debt. It helps you see whether the payment fits your budget and how the total cost changes with a different rate or repayment term.
How the calculation works
The calculation uses an annuity formula where the payment stays the same while the split between interest and principal changes over time. You enter the loan amount, annual interest rate and number of years, and the calculator estimates the monthly payment and total paid amount.
Practical example
Example: a CZK 300,000 loan for 6 years at 8% per year has a very different total cost than the same loan for 10 years. A longer term lowers the monthly burden but usually increases the total amount paid.
What to watch out for
Watch the difference between interest rate and APR. Real loan costs may include fees, repayment insurance, payment holidays or penalties for early repayment. Use the calculator as a first orientation before reading the contract.
FAQ
What is the difference between interest and APR?
Interest describes the price of borrowed money, while APR also includes other mandatory loan costs.
Why does a longer term increase total cost?
Because interest is charged for a longer period, even if the monthly payment is lower.
Can I use this calculator for a mortgage?
Mathematically yes, but the mortgage calculator is better for home loans because it includes additional mortgage indicators.
Does the calculator include fees?
No. It calculates basic annuity repayment without bank fees or insurance.
