This revaluation rate calculator, provided by Hesapstan, applies the current official rate you enter to a current value and shows the revalued amount.
Formula
Revalued amount = current value × (1 + rate / 100). The increase is shown separately.
Keep the periods distinct
GİB set the official annual revaluation rate for 2025 at 25.49%; that rate updates many statutory limits and fees for 2026. The 4.19% rate announced for the first 2026 provisional tax period is a separate period rate. The tool makes you identify which type you are applying.
Rate source
This tool does not automatically store the current official rate for any year. Verify the current rate from the relevant official communiqué before entering it.
Revaluation example
Applying 25.49% to 100,000 TL gives a 25,490 TL increase and a 125,490 TL revalued amount. If a provisional-period rate is selected, the same formula uses that period rate.
The tool does not fetch live rates; annual, provisional-period or custom-rate choice must be based on the user’s official source.
The result is an arithmetic interpretation of entered values; it does not replace official action or professional review.
Outside the scope
- No live application, approval or official-record check is performed.
- The tool cannot validate the real-world correctness of wrong input values.
- Current special conditions should be confirmed with the relevant institution, bank, brand or official source.
Frequently Asked Questions
Does this tool fetch the current rate?
No. It shows the 2025 annual reference (25.49%) and the first 2026 provisional-period reference (4.19%), then calculates with the rate you enter.
Is the annual rate the same as the provisional tax period rate?
No, they are two legally distinct rates for different purposes with different numeric values. Which one applies depends on your purpose (updating a fixed asset/fee vs. adjusting a provisional tax base).
Is the result a final decision?
No. The tool calculates from entered values only and does not replace an official, medical, legal, financial or institutional decision.
What happens with wrong input?
Invalid or out-of-range values are rejected; accepted results still depend on the values entered by the user.
How should I use the example result?
Use it for planning, checking and comparison; verify with the relevant official source, institution, bank, brand or professional before acting.
Which fields affect the result most?
Visible amount, rate, date, day, installment, score or selector fields directly change the result.
Does it use live data or submit an application?
No. It does not perform live application, approval, inquiry or official-record checks.
