How this cost comparison works
Your required payments + voluntary payments + approved back payments= Your gross commitment
Gross commitment − confirmed cash tax saving= Your net cost
Net cost is shown only when a cash tax saving is confirmed. If tax treatment is unknown, only gross cost is shown. Excluding tax relief is a scenario choice, not a finding that no relief exists.
Employer or government funding is displayed separately. It does not reduce your personal cost. A deduction base is not a cash saving, and tax relief paid into a pension is not a personal refund. Contributions tax, fees, investment returns and the value of future benefits are outside this comparison.
Worked example with invented amounts
In TRY, suppose you pay 2,400 required contributions, 600 voluntary contributions and an accepted 1,200 back payment. Your total commitment is 4,200. A separately confirmed 300 cash tax saving would make the cost 3,900. Over 12 budget months, that is 350 before or 325 after the saving. Separate employer funding of 1,000 raises combined payments to 5,200; your cost stays 3,900. These example amounts are not legal rates, an official quote or a recommended payment.
Budget months do not change a deadline
The monthly amount is a planning equivalent. A back payment can be due in one instalment, and tax relief can arrive later. Use a single currency and the same selected payment period. Check for credits, waivers and corrections before treating an amount as payable.
Your Türkiye checklist
- If your service history combines employee, independent or public-service periods, ask SGK to confirm the relevant status before comparing extra payments.
- If the proposed gap matches an authorized borçlanma category, request a written day-and-cost assessment and use its deadline; otherwise pursue a record investigation or prospective coverage.
- If choosing between voluntary SGK and BES, compare their different benefit purposes and separate tax deductions from vested and unvested government support.
