Fon.org.tr — TEFAS Fund Returns & Real (Inflation-Adjusted) Returns

Search TEFAS funds and see returns adjusted for inflation and FX, with charts. Pin your funds for one-click tracking.

See how Turkish mutual funds on TEFAS have actually performed — nominal and, more importantly, adjusted for inflation and currency — the moment you type a fund code, without leaving your browser. A nominal number on its own tells you nothing. A fund that returned 60% in a year when inflation ran at 65% lost you purchasing power. The Fon.org.tr extension shows exactly that gap: it recomputes any TEFAS fund's return against Turkish CPI (TÜFE), the independent ENAG index, the US dollar, the dollar plus US CPI, or the euro — and draws that benchmark on the chart so you can see whether the fund's line sits above or below it. WHAT IT DOES Instant search by fund code. Type a three-letter TEFAS code, such as AFT, and get the fund's latest price and return. Nominal and real return, side by side. 1-month, 6-month and year-to-date periods, plus each fund's 1-year nominal return next to its real return under the benchmark you choose. You pick the purchasing-power benchmark: official CPI (TÜFE), ENAG, USD, USD + US CPI, or EUR. The same fund looks very different depending on which yardstick you hold it to. Price charts. 1-month, 3-month, 6-month, 1-year, 5-year and all-time ranges, with the benchmark drawn as a dashed overlay. Fund line below the dashed line means the fund did not keep up with the cost of living over that window. Pin the funds you follow. Pin with 📌 and they're at the top of the popup every time you open it. Pins are stored on your device — no account needed. Favorites sync across devices.
