Hesapstan's loan calculator helps users dealing with loans in Turkey estimate monthly payment, total cost, BSMV, KKDF, YMO and amortization from loan amount, monthly interest rate and term. This calculator is provided by Hesapstan for Turkey-based loan calculations that need clear cost breakdowns before comparing bank offers.
What does this loan calculator calculate?
The Hesapstan loan calculator estimates loan payments in Turkey from the loan amount, monthly interest rate and term. It shows the base payment, first-month total, total repayment, total interest, BSMV, KKDF, estimated YMO and an amortization schedule.
- It calculates the fixed base payment using the monthly interest rate.
- It separates principal, interest, BSMV, KKDF, total payment and remaining balance by month.
- It shows total repayment, total interest and total tax separately.
- It estimates YMO, but this is not the official bank annual cost rate because file fees, insurance and other charges are excluded.
- It includes an early repayment simulation when the user enters a month and an extra payment amount.
This calculator is for information only. Real bank payments can differ because of the bank offer, loan type, fees, insurance, customer profile and contract terms.
Why the monthly interest rate matters
This calculator uses the monthly interest rate. If you enter an annual rate into the monthly rate field, the result will be seriously distorted. In Turkey, loan offers may show different rate concepts, so the rate type must be checked before calculation.
For example, if a bank gives a monthly rate of 3.50%, enter 3.50. If the document shows an annual cost rate or annual interest rate, do not enter that number directly into the monthly rate field.
Entering an annual rate as a monthly rate can make the installment and total cost appear far higher than they should. Always confirm the rate label in the bank offer.
How is the loan installment calculated?
The installment is calculated with the amortization method. In an amortized loan, the early payments contain more interest and less principal; over time, the interest share decreases and the principal share increases.
Simplified formula: monthly base payment = principal × [r × (1+r)^n] / [(1+r)^n − 1]. Here r is the monthly interest rate and n is the term in months.
The runtime calculation shows the fixed base payment separately. BSMV and KKDF are calculated from each month's interest and then added to that month's total payment.
How are BSMV and KKDF applied?
In this calculator, BSMV and KKDF are applied to the monthly interest amount, not to the principal. The current runtime assumption is 15% BSMV and 15% KKDF.
- BSMV is treated as a tax calculated on interest.
- KKDF is treated as a fund charge calculated on interest.
- The principal repayment is not the tax base for these two items.
- As the interest amount falls over time, the monthly tax amounts may also fall.
This content explains the calculator's current behavior. For formal decisions, check the current regulation, bank contract and product-specific tax treatment.
Why is the first-month total different from the base payment?
The base payment is the fixed amortized loan payment before monthly interest-based tax items are added. The first-month total adds BSMV and KKDF generated from the first month's interest.
Because the remaining balance is highest at the beginning, the first month's interest and tax items are usually higher than later months.
For monthly budgeting, look at the first-month total and the amortization schedule, not only at the base payment.
What does the amortization schedule show?
The amortization schedule shows how each monthly payment is divided into principal, interest, BSMV, KKDF, total payment and remaining balance. It explains where the money goes over the life of the loan.
- Month: the payment number.
- Principal: the part that reduces the debt.
- Interest: the cost calculated from the remaining balance.
- BSMV and KKDF: tax/fund amounts tied to the interest portion.
- Total: the estimated payment for that month.
- Balance: the remaining principal after payment.
How should total repayment, total interest and total tax be read?
Total repayment is the estimated sum of all monthly total payments. Total interest shows only the interest cost, while total tax shows the combined BSMV and KKDF amounts.
This distinction matters because a longer term can reduce the monthly burden while increasing total interest and total tax over the full loan period.
The total repayment result does not automatically include file fees, insurance, appraisal, mortgage, bank commissions or campaign-specific charges.
What is YMO and why is it only an estimate here?
YMO is a Turkish annual cost rate concept used to express the cost of credit in one annualized indicator. In this calculator, YMO is estimated from monthly cash flows that include interest, BSMV and KKDF, but exclude bank fees and insurance.
The Banks Association of Türkiye's YMO approach may use items such as loan disbursement amount, annual interest rate, BSMV rate, installment count, disbursement date, allocation fee, appraisal fee, mortgage/pledge fee and insurance. Therefore, the Hesapstan YMO should not be read as an official bank YMO.
The estimated YMO shown here can differ from the annual cost rate in a bank offer. Use the bank's pre-contract information form for formal comparison.
How does the early repayment simulation work?
The early repayment simulation estimates what happens if you make an additional principal payment in a chosen month. It shows how the remaining balance and future interest burden may decrease.
The user enters the month of extra payment and the extra amount. The calculator deducts that amount from the remaining balance and estimates how many months earlier the loan may close and how much cost may be saved.
The simulation does not fully calculate bank closure fees, insurance refunds, mortgage early repayment compensation or contract-specific rules. It is a decision-support estimate, not a formal settlement statement.
How do loan types affect the calculation?
This general loan calculator explains the core installment and cost logic, but personal, auto and mortgage loans may have different fees, collateral rules, insurance requirements and early repayment conditions.
- Personal loans are usually shorter-term consumer finance products.
- Auto loans may involve vehicle pledge, insurance or extra conditions.
- Mortgage loans may involve appraisal, mortgage registration, insurance and specific early repayment rules.
- This general calculator does not automatically apply every product-specific condition.
How should this result be used for loan comparison?
Use this result to understand one loan scenario. When comparing two bank offers, compare total repayment, total interest, taxes, YMO, insurance, fees and contractual conditions together.
A lower monthly rate may not always mean a lower total cost if compulsory insurance, allocation fees or other charges are higher. The calculator helps you ask better questions, but it does not replace the bank offer.
Example loan calculation
Suppose a user enters a 150,000 TL loan, 3.20% monthly interest and a 24-month term. The calculator first finds the fixed base payment, then calculates monthly interest, BSMV and KKDF from the remaining balance.
In the first month, the remaining balance is highest, so the interest and related tax items are generally higher. As the principal decreases, the interest portion can fall over time.
This example does not represent any bank offer. The actual rate, term, fees and insurance must come from the bank.
Common mistakes
The most common loan calculation mistakes are entering the wrong rate type and treating an estimate as a bank-approved offer.
- Entering an annual rate into the monthly rate field.
- Ignoring file fees and insurance.
- Reading estimated YMO as an official annual cost rate.
- Ignoring possible mortgage early repayment compensation.
- Looking only at the monthly payment and not at total repayment.
- Comparing loans without matching term, amount and fees.
Limits of this calculator
This calculator is informational and does not replace a bank offer, credit approval, formal contract or professional financial advice. Results are limited to the user's inputs and the current calculation assumptions.
- It does not pull live bank interest rates.
- It does not assess income, credit score or borrowing eligibility.
- It does not automatically include file fees, insurance, appraisal, mortgage or bank commissions.
- It does not apply every special condition of mortgage, auto or personal loans.
- It does not fully calculate early repayment compensation or closure rules.
- The YMO result is not the official bank annual cost rate.
Before using a loan, check the bank's current offer, pre-contract information, repayment schedule and all cost items.
Frequently Asked Questions
How is a loan payment calculated in Turkey?
The calculator uses the loan amount, monthly interest rate and term to calculate a fixed base payment with the amortization formula. It then adds BSMV and KKDF based on the monthly interest amount.
Is the monthly rate the same as the annual rate?
No. This calculator asks for the monthly interest rate. Entering an annual rate directly into the monthly rate field will produce an incorrect result.
Are BSMV and KKDF calculated on the full loan amount?
No. In this calculator they are calculated on each month's interest amount, not on the principal.
Is the YMO shown here official?
No. It is an estimate that excludes items such as file fees, insurance and other bank charges. The official annual cost rate should be taken from the bank offer.
Does the early repayment simulation match the bank settlement?
No. It estimates the effect of additional principal payment, but it does not fully include closure fees, insurance refunds or contract-specific conditions.
