Instalment
What you pay each month. In an equal-instalment (annuity) plan it stays the same for the whole term; the last one may differ by a few kuruş of rounding.
PAYMENT SCHEDULE
How to read a payment schedule
The table your bank hands you shows, row by row, where each instalment goes. Here are the columns and where the numbers come from; your own schedule is in the Bankacı app.
The columns
Principal
The part of the instalment that reduces the debt. Small in the first months, large in the last; the column adds up to the loan amount.
Interest
That month's interest: outstanding principal × monthly contractual rate. As the principal falls, so does the interest.
KKDF and BSMV
Two levies taken as a share of the interest: 15% + 15% on personal and car loans, only 5% BSMV on business loans, none on housing. They go to the state, not the bank, and sit inside the instalment.
Balance
What is still owed after the instalment. Closing the loan today means paying this principal, plus the interest accrued to that day and any compensation.
Why is interest high at first?
Interest runs each month on what is still owed. At the start the whole loan is outstanding, so the interest share is large and the principal share small; with a fixed instalment the balance shifts toward principal as the months pass. That is why paying off early does not refund interest already paid, but does spare the interest still to come.
The taxed rate
The instalment is computed not at the contractual rate but at the taxed one: contractual × (1 + KKDF + BSMV). A 3% monthly rate on a personal loan is a 3.90% taxed rate. Compare offers on the same tax footing; the fairest measure is the annual cost rate.
Early payoff and part payments
You may pay the outstanding principal off in full or in part before the term ends. No compensation is charged on personal and car loans; on housing loans it is capped by statute (1% when the remaining term is up to 36 months, 2% beyond). After a part payment the instalment or the term is rebuilt.
One loan, seven different plans
The equal-instalment plan is not the only option. Your banker can work out seven plans for the same amount and term; all of them repay the same loan, and what differs is how the instalment behaves over time.
Standard fixed instalment
The same from first to last. The easiest to follow if you know your budget.
Prepaid interest
You pay part of the interest when the loan is drawn, and the monthly instalment is lower.
Equal principal
The instalment starts high and falls every month. Usually the one with the least interest overall.
Custom / balloon
A large payment lands on a date you choose — if you are expecting a bonus or a sale.
Grace period
The first months are interest only. The lightest start, the heaviest total.
Increasing instalment
The instalment climbs in steps — if your income will.
Decreasing instalment
The instalment falls in steps — if you want the weight early.
One thing is worth knowing: the plan that costs least overall and the plan with the smallest first instalment are not the same plan. Choosing by the first instalment usually costs more in total.

Frequently asked questions
Is total interest the sum of the interest column?
Yes. The interest column adds up to the total interest, the KKDF and BSMV columns to the total taxes, and the instalments to those two plus the principal.
Why might the table differ from the bank's by a few kuruş?
Banks round in a different order and may add broken-period interest for the days to the first instalment. The difference is at the kuruş level; the shape of the plan is the same.
Are fees in the table?
No. Arrangement fees, insurance and appraisal costs sit outside the instalment; ask for them separately in the offer.
