Nominal raises versus real ones
A bigger number on your payslip feels like progress, but it only counts if it outruns the rising cost of rice, rent, transport, and electricity. This calculator separates the two. It grows your old salary forward by the average inflation you have lived through, producing the figure you would need today just to stand still, then compares that against what you actually earn now. The difference is your real gain or loss: the part of your raise that genuinely improved your buying power, as opposed to the part that merely kept pace with prices.
Inflation in this tool is your own assumption, since the official rate varies year to year and is published by the Philippine Statistics Authority rather than fixed in any tax rule. Use a multi-year average that reflects the period you worked, and remember it is an estimate. The structure of the calculation, compounding a starting figure by an annual rate, is stable and reliable; the precise inflation number you feed it is the part to source carefully and revisit.
Tracing a PHP 400,000 salary forward five years
Suppose you started on PHP 400,000 a year five years ago and now earn PHP 650,000, and you reckon inflation has averaged 4 percent over that stretch. Grow the PHP 400,000 by 4 percent compounded for five years and you get about PHP 486,661, which is what the old salary would need to be today just to hold its ground. Since you actually earn PHP 650,000, you are ahead by roughly PHP 163,339 in real terms.

The chart contrasts three figures: where you started, where inflation alone would have carried that salary, and where you actually landed. The gap between the middle bar and the tallest one is your real raise.
The real growth rate, and why it is the honest number
The headline nominal growth rate in this example is 10.2 percent a year, which sounds excellent. But once inflation is stripped out, your true annual raise is 6.0 percent. That real rate is the figure to carry around, because it tells you how fast your standard of living is actually improving rather than how fast the digits are. Two people with identical nominal raises can have very different real outcomes if they worked through different inflation environments. The real rate puts everyone on the same footing.
The arithmetic the tool uses is a geometric average, not a simple division, so it correctly reflects compounding over the years rather than overstating the annual pace. That is why it needs both a starting salary above zero and at least one year elapsed to return a meaningful rate. If your real gain comes out negative, it means your pay rose in pesos but lost ground against prices, a quietly common experience in higher-inflation years that a glance at the payslip would never reveal.
A trap hiding in long job tenures
The longer the period you examine, the more a single average inflation figure can mislead, because inflation is rarely steady. A decade that included a couple of high-inflation years and several mild ones is not well captured by one blended number, so a long lookback deserves a more careful average or a split into sub-periods. A second subtlety: this tool measures purchasing power, not take-home pay. It works on gross salary figures and does not net out income tax or the SSS, PhilHealth, and Pag-IBIG contributions, so two salaries that look equal in real gross terms can differ once tax is applied. For the after-tax picture, pair this with a take-home calculator, and source your inflation figures from the Philippine Statistics Authority.
What inflation figure should I use?
Use the average annual inflation rate over the years you are comparing, ideally drawn from the Philippine Statistics Authority's consumer price index for the period rather than a single recent month. Your personal inflation can differ from the headline if your spending leans heavily on categories like rent or schooling that moved faster or slower than the basket average. When unsure, run the tool at a couple of plausible rates to see how sensitive your result is.
Does this account for income tax on my salary?
No. The comparison is on gross salary and purchasing power only, so it ignores income tax and mandatory contributions entirely. A raise that looks healthy in real gross terms can be slimmer after the graduated tax and contributions are deducted, especially if it pushed you into a higher band. Treat the real growth rate here as a measure of buying power, and use a take-home pay tool for the net view.
How is this different from a cost-of-living raise?
A cost-of-living raise is an adjustment meant only to match inflation, so it keeps your real pay flat rather than raising it. This calculator measures whether your total raises, cost-of-living and merit combined, beat inflation. If your only increases were cost-of-living adjustments set exactly at the inflation rate, this tool would show a real gain of roughly zero, confirming you held steady without truly getting ahead.
