The situation
Inflation figures get reported as a percentage that means nothing on its own. Most people want the concrete answer: is my raise actually a raise, and what has my money lost?
What I built
Six calculators, each answering one question in pesos rather than percentages — purchasing power, salary, a raise, savings erosion, a wealth projection, and a timeline. They run on official Philippine price data. Every calculation happens on your own device: nothing is uploaded, and there is no account to create.
What it lets people do
- Check whether a raise actually beat inflation
- See what your savings are really worth now
- Track the peso's purchasing power over time
- Use all of it without an account, with nothing sent anywhere
