Türkiye deposits average 43.79%: what TRY 100,000 earns net in 32 days
The CBRT data released on October 8 put the weighted-average rate on lira deposits with maturities up to three months at 43.79% for the week of October 2. A 32-day comparison applying that rate to all TRY 100,000 produces about TRY 3,167 net, while a 44% VOV promotion yields about TRY 2,546 because TRY 20,000 earns no interest.
In this article
The short answer: 43.79% is the CBRT’s weighted average for newly opened lira deposits with maturities up to three months, not a bank offer available to everyone. Applying it to all TRY 100,000 for 32 days gives about TRY 3,167.28 net. A promotion with a higher headline rate can pay less if part of the balance earns no interest.
Three critical developments
- The CBRT series released on October 8 put the weighted-average rate on lira deposits up to three months at 43.79% for the week of October 2. It is a sector transaction average, not a retail quote.
- “Vadeli mevduat” appeared among active Google Trends Türkiye queries with 2,000+ searches and 400% growth over the past 24 hours. Search interest is not a product ranking or quality measure.
- Alternatif Bank VOV publishes a 44% introductory rate and Fibabanka a 42% digital Kiraz welcome rate. Both leave TRY 20,000 without interest in the TRY 100,000 balance tier.
32-day comparison for TRY 100,000
Each row uses 32 days and 17.5% withholding. The CBRT row is a mathematical sector-average scenario, not an available product quote.
| Comparison | Annual gross rate | Interest-bearing amount | 32-day net interest |
|---|---|---|---|
| CBRT average, up to 3 months | 43.79% | TRY 100,000 assumption | TRY 3,167.28 |
| Alternatif Bank VOV introductory | 44% | TRY 80,000; TRY 20,000 idle | TRY 2,545.97 |
| Fibabanka digital Kiraz welcome | 42% | TRY 80,000; TRY 20,000 idle | TRY 2,430.25 |
| If 44% applied to all TRY 100,000 | 44% | TRY 100,000 assumption | TRY 3,182.47 |
What does the 43.79% deposit rate measure?
The CBRT weekly flow series is a weighted average of rates applied to deposits newly opened or renewed across the banking sector during the reference week. The 43.79% figure for lira deposits with maturities up to three months in the week of October 2 is not one bank’s advertisement, the highest market rate or an offer every customer can obtain. The CBRT released the data on October 8.
How does TRY 100,000 produce TRY 3,167 over 32 days?
TRY 100,000 × 43.79% × 32 / 365 gives about TRY 3,839.12 gross interest. Keeping 82.5% after the assumed 17.5% withholding leaves TRY 3,167.28, for a nominal maturity balance of about TRY 103,167.28. The scenario assumes all TRY 100,000 earns interest for 32 days. Because the sector average is not an available product, the result is comparative arithmetic only.
What do the official bank conditions say?
Alternatif Bank VOV publishes a 44% introductory and 34% standard rate for the TRY 20,000–250,000 band; the introductory period lasts 45 days. Fibabanka’s official table lists 42% for the digital Kiraz welcome rate, 41% for the standard welcome rate and 34% for the advantageous standard rate. Both banks set aside TRY 20,000 without interest in the TRY 100,000–249,999 tier, leaving only TRY 80,000 to earn interest.
Why can 44% pay less than 43.79%?
The percentage is only one input. Applying 44% to TRY 80,000 produces about TRY 2,545.97 net over 32 days, while applying 43.79% to all TRY 100,000 produces about TRY 3,167.28. The roughly TRY 621.30 gap comes mainly from the TRY 20,000 idle balance, not the 0.21-point rate difference. A ranking that omits total cash, interest-bearing cash, term and withholding is therefore misleading.
What is the difference between 42% and 44%?
For the same TRY 80,000 interest-bearing balance and 32 days, a 42% digital Kiraz rate produces about TRY 2,430.25 net and 44% produces about TRY 2,545.97, a difference of TRY 115.73. If the higher rate requires a channel, product or eligibility condition, its separate cost and risk must be assessed. The personal rate shown in an app can differ from the maximum on the public table.
MY MONEY, BUSINESS AND PORTFOLIO · What does this mean?
A saver should compare maturity proceeds, the idle balance and the post-promotion standard rate together. A business treasury should also account for early-withdrawal probability and daily liquidity needs; breaking the term can eliminate expected interest. For a portfolio, the nominal net deposit return is not the same as a real return: inflation, reinvestment and opportunity cost remain. A 32-day real-return comparison needs price change over the same 32 days; annual CPI should not be compared directly with one month of interest.
Calculation notes
The CBRT’s 43.79% figure is the weekly flow weighted average for lira deposits up to three months in the week of October 2, released on October 8. Bank rates were taken from official product pages accessed on October 9. Calculations use simple interest, a 365-day basis, 32 days and 17.5% withholding; fees, fund returns, inflation, early withdrawal and personal pricing are excluded. Google Trends measures search interest, not financial outcomes or product quality. This is not investment advice.
