Debt adjusted for inflation
The amount in koruna, purchasing power and the ratio to economic output describe different things. Compare the same years from three angles and see why inflation alone does not solve debt.
Prepared and sources checked on 24 October 2026 · Independent educational website
Three compatible perspectives
- Nominal debt: the number of koruna reported on a given date.
- Debt in December 2025 prices: the historical amount adjusted using consumer prices, as a guide to purchasing power.
- State debt / GDP: the ratio to annual economic output, not the same indicator as public debt / GDP.
This page uses state debt in all three perspectives. We do not mix in broader public debt from the European comparison.

How we calculate December 2025 prices
We multiply each year-end debt balance by the successive December year-on-year CPI increases up to 2025. The price base is December 2025, not today's prices. For 2022–2025 we use December changes of 15.8%, 6.9%, 3.0% and 2.1%. These are not annual average inflation rates.
The household consumer basket is neither the price of government purchases nor the GDP deflator. The result is not an accounting revaluation of debt, a change in liabilities to creditors or a precise measure of the tax burden.
Inflation does not erase a loan
For a fixed koruna liability, rising prices can reduce the real purchasing power of repayments. Creditors are still entitled to the agreed koruna amount. Inflation can also raise new market interest rates, wages, indexed expenditure and the cost of government services.
Fictional example: with prices up 10%, debt of 100 is equivalent to approximately 90.9 in original purchasing power, not 90. This does not mean that the public budget has automatically saved 9.1.
