Salary inflation calculator

What the result means

The equivalent salary is the monthly amount that would preserve the purchasing power of the salary you entered, using the selected country's CPI. The required increase compares that amount with your original salary. The monthly shortfall shows the gap if your pay has stayed unchanged.

Purchasing-power loss answers a different question: how much less your unchanged salary buys. It is not the same percentage as the required raise because the measures use different bases. It does not represent money removed from your account, wages owed or the sum of losses over all intervening months.

Enter your regular monthly salary after the last raise and keep a consistent basis: a gross input produces a gross result; a net input produces a net result. Annual salaries, bonuses and taxes are not converted.

A period based on available data

The month of your last raise is the starting reference. Its price level is compared with the country's latest available month: changes accumulate from the month after the raise. No exact payday is assumed. Selecting the latest month with data leaves no change between reference periods, so the adjustment is zero.

The server selects the ending month when you calculate. As valid new data is added to our own system, calculation automatically extends to the new available month for that country. Countries need not share the same ending month. Inflation is not projected to today and missing months are not filled in.

Methodology

S is the monthly salary entered and F is the price-change factor. With comparable indices, F = ending CPI / starting CPI. For Argentina, national CPI monthly changes are compounded by multiplying (1 + rate / 100), from the month after the starting reference through the latest available month. Monthly percentages are not added.

• Equivalent salary: S × F.
• Percentage adjustment: (F − 1) × 100.
• Monthly gap: S × F − S, at ending-month prices.
• Purchasing-power loss: (1 − 1 / F) × 100. Unchanged pay buys S / F at starting-month prices.

Results are rounded only for display. For Argentina, compounding rounded published rates is an approximation and may differ from the official year-on-year change. If prices fell over the period, the tool shows a purchasing-power gain: a negative equivalent adjustment is not a recommendation to cut pay.

Sources, privacy and limitations

Argentina uses INDEC's national CPI via ArgentinaDatos, without mixing in the GBA series. Other countries use CPI indices from CEPALSTAT, indicator 365. The form identifies the agency and coverage; each result shows the export date and source SHA-256 fingerprint. The export date is not the month of the latest CPI.

CPI does not exactly represent your personal expenses. This reference does not set a legally required salary, guarantee a raise or replace a pay negotiation. It does not account for changes in role, productivity, hours worked, taxes or exchange rates. El Salvador uses its local CPI even though pay is expressed in USD. In Venezuela, use a consistent monetary denomination; historical bolívar denominations are not converted.

Calculation takes place on the server without publishing the historical file. We do not store your salary or a calculation history. Security verification uses Cloudflare Turnstile without sending it your salary, country or selected months; hosting may retain technical access logs.
