This alimony increase calculator is provided by Hesapstan for estimating the updated alimony amount in Turkey by applying a court-stated rate, a manually entered TÜFE/ÜFE rate, or a custom increase rate to the current amount.
What does this calculator calculate?
This alimony increase calculator applies the increase rate entered by the user to the current monthly alimony amount and estimates the new monthly amount.
It also shows the monthly increase, optional annual difference and, if the increase was not applied for several months, an estimated accumulated difference. This makes it useful not only for the new monthly amount but also for a simple past-difference estimate.
This tool does not determine which rate is legally correct. You must enter the rate from the court decision, the relevant TÜFE/ÜFE period, a settlement document or your own scenario.
What does alimony increase mean in Turkey?
Alimony increase means updating an existing monthly alimony amount by a specific percentage. The rate may come from a court decision, a settlement, or an index such as TÜFE/ÜFE when that index is relevant to the case.
The calculator uses “alimony” as a general term. Child-related alimony, poverty alimony, temporary alimony and support between relatives may have different legal contexts in Turkey. This tool does not decide rights or legal conditions; it only applies the rate you enter.
Does the alimony type change the result?
The alimony type selector is informational only in this calculator; it does not change the formula. The same percentage-increase formula is used for all selected types.
- İştirak nafakası usually refers to child-related alimony.
- Yoksulluk nafakası may relate to a spouse who becomes economically weaker after divorce.
- Tedbir nafakası may be temporary support while a case is pending.
- Yardım nafakası relates to support obligations between certain relatives.
The selected alimony type helps you read the result in context. It is not a legal classification decision and does not change the calculation.
How is alimony increase calculated?
The updated alimony is calculated by multiplying the current alimony by one plus the increase rate divided by 100.
Formula: new alimony = current alimony × (1 + increase rate / 100). The monthly increase is the difference between the new amount and the current amount.
- Current alimony: the existing monthly payment.
- Increase rate: the percentage entered by the user.
- Monthly increase: the added amount after the increase.
- Accumulated difference: monthly increase multiplied by the number of unpaid or unapplied months.
Court rate, TÜFE/ÜFE rate and custom rate
The rate-source selection records why you are using a specific percentage. The calculation itself remains the same.
Use court decision rate when the judgment states a fixed rate. Use manually entered TÜFE/ÜFE when you have obtained the relevant period rate separately. Use custom rate for a scenario or informal estimate.
This calculator does not fetch TÜİK data automatically and does not choose the relevant TÜFE/ÜFE period. Check the correct rate from an official data source, court decision or case document before formal use.
How is accumulated difference calculated?
Accumulated difference is calculated by multiplying the monthly increase by the number of months for which the increase was not applied.
For example, if the monthly increase is 1,500 TL and the increase was not applied for 7 months, the estimated accumulated difference is 10,500 TL. This is a mathematical estimate only; it does not include enforcement interest, payment dates or legal objections.
If the month field is empty or 0, the accumulated difference row is not shown. If you enter a positive number of months, the estimated accumulated difference is displayed separately.
Example calculation
If the current monthly alimony is 12,000 TL and the increase rate is 20%, the monthly increase is 2,400 TL and the new monthly alimony is 14,400 TL.
If that increase was not applied for 4 months, the accumulated difference estimate is 2,400 × 4 = 9,600 TL. If the annual difference option is shown, the yearly difference is 28,800 TL.
How to use the calculator
- Enter the current monthly alimony amount.
- Choose the rate source: court decision, manually entered TÜFE/ÜFE or custom rate.
- Enter the increase rate as a percentage.
- Optionally choose the alimony type for context.
- Enter the number of months if you want to estimate accumulated difference.
- Review the new monthly amount, monthly increase and any additional difference rows.
The result is informational. For enforcement, litigation, settlement or official use, verify the court decision, correct rate, payment history and legal context.
Common mistakes
- Using the wrong TÜFE/ÜFE period instead of the one required by the court decision.
- Confusing monthly increase with the new monthly alimony amount.
- Entering the wrong number of months for accumulated difference.
- Reading the accumulated difference as an enforcement debt including interest.
- Assuming the alimony type selector changes the legal formula.
These mistakes can make the estimate higher or lower than the amount that may be accepted in a formal context. Past differences and enforcement steps should be checked separately.
Limitations of this calculator
This calculator only applies the user-entered rate to the current monthly alimony. It does not determine the legal rate, retrieve TÜİK data or interpret a court decision.
- It does not predict the result of an alimony increase lawsuit.
- It does not automatically choose the correct TÜFE/ÜFE period.
- It does not calculate enforcement interest or enforcement costs.
- It does not decide whether past difference is legally collectible.
- It does not apply different legal conditions for different alimony types.
The applicable increase may depend on the wording of the court decision, the parties’ agreement, the alimony type and the specific case. Do not use the result as a final legal debt calculation without verification.
Frequently Asked Questions
Does this calculator determine the legal alimony increase rate?
No. It applies the rate you enter. The legally correct rate must come from the court decision, agreement or relevant official data.
Does it fetch TÜFE/ÜFE automatically?
No. TÜFE/ÜFE is entered manually. You must check the correct period and rate separately.
What is accumulated alimony difference?
It is the monthly increase multiplied by the number of months for which the increase was not applied.
Does alimony type change the calculation?
No. The type is shown for context only; the same percentage formula is used.
Can I use the result directly in enforcement?
Not by itself. Enforcement use requires the court decision, payment history, correct rate and possibly legal review.
