Serbia Pension Hike: Fund Still Weighing Three Formulas

As of September 3, Serbia’s Pension and Disability Insurance Fund (PIO Fund) had announced neither which of the three legal formulas it will apply nor what percentage pensions will rise by from December of this year. On August 29 in Uzice, Aleksandar Vucic said citizens would learn the new percentage within seven days, and that the increase could track wage growth. That deadline falls right around now, on top of an earlier one, September 6, which the president had set for letters to pensioners.

The adjustment applies starting with the December 2026 pension, which is paid out in January 2027. Before then, by law, officials first have to determine which of the three models under Article 80 of the Law on Pension and Disability Insurance applies, since the entire calculation depends on that choice.

Three formulas, one threshold

Which formula applies depends on total pension spending as a share of gross domestic product:

• if that share is below 10 percent, pensions track the change in the average net wage. This is the most favorable option for pensioners when wages grow faster than prices.
• if the share falls between 10 and 10.5 percent, the Swiss formula applies: half the increase is set by wage growth, half by consumer price growth.
• if the share is above 10.5 percent, pensions track consumer prices only.

The calculation uses official data on the change in the average net wage and consumer prices over the 12 months through June 2026, compared with the preceding 12 months. The PIO Fund calculates the share using its own payment data together with the first published GDP figure from the Republic Statistical Office, and the law treats that calculation as final.

The 12 percent and 8 percent figures circulating in some media are, based on available sources, illustrative examples of how each of the three models would play out in practice, not an official forecast or a confirmed number.

What the last calculation showed

At the previous adjustment, pensions’ measured share of GDP came in at 9.98 percent, just under the first threshold, so pensions tracked the growth of the average net wage. Aleksandra Jovanovic, editor of the Penzin portal, warned in an interview with Nova ekonomija in late 2025 that this result had been a close call:

We could very easily end up with pensions being adjusted under the third option, by inflation alone. In that case, pensioners’ real standard of living falls.

Jovanovic made that point in the context of slower GDP growth in the coming years, when pensions’ share of GDP rises even without any change to the adjustment policy itself, since the economy then grows more slowly than the needs of a growing number of pensioners require.

The data the PIO Fund is using for June 2026 show an average gross wage of 166,123 dinars and an average net wage of 120,401 dinars. For the first six months of 2026, compared with the same period last year, the average net wage was nominally higher by 11.5 percent, and by 8.4 percent in real terms. If that growth rate ends up as the basis for the adjustment, it would mean the first, most favorable model for pensioners applies.

Serbia has about 1.7 million pensioners, roughly a quarter of the population, so every tenth of a percentage point in the final calculation shifts the amount that reaches a large number of households at year’s end. The PIO Fund has not yet announced a date for when the final percentage will be officially confirmed.
