What is YOUR inflation?

The INPC is the inflation of the average household. Split what you spend in a month into eight categories and see yours, with INEGI’s official annual inflation for each one.

Split what you spend in a month

Type, in pesos, what you spend each month in each category. Whatever you leave empty counts as zero. If you type nothing, the calculation uses the INPC weights: the average household.

Groceries from the supermarket, the market or the corner store: tortillas, chicken, milk, soda, and ready-made food to take home. Alcohol and cigarettes count here too. INEGI group: «Alimentos, bebidas y tabaco».

Bus, colectivo, metro, taxi, gas, and what a car or a motorbike costs. INEGI group: «Transporte».

Tuition, school supplies and books; also internet and pay TV, cinema, streaming, parties and trips. INEGI counts them in the same group. INEGI group: «Educación y esparcimiento».

Rent, electricity, gas, water and your phone plan, which INEGI counts here. If you live with your family and pay no rent, little goes here. INEGI group: «Vivienda».

Loncherías, fondas, taco stands and restaurants. INEGI counts them under «Otros servicios», together with paperwork and professional services, which weigh far less. INEGI group: «Otros servicios».

Clothes, sneakers, shoes, school uniforms and laundry. INEGI group: «Ropa, calzado y accesorios».

Medicine and doctor visits, and also shampoo, deodorant, toilet paper and haircuts. INEGI group: «Salud y cuidado personal».

Furniture, appliances, a phone or a computer when you buy one, detergent and cleaning products. INEGI group: «Muebles, aparatos y accesorios domésticos».

This is the inflation of the average household: 3.44 % with INEGI’s weights (the official INPC is 3.45 %). Type what you spend to see yours.

This is a calculation with official data, not a recommendation: it tells you how much the prices of what you buy went up in a year, not what to do with your money. Each category’s inflation is the national average; in your city, or in what you buy inside each category, it can be different.

Why does the calculation with INEGI’s weights give 3.44 % and not 3.45 %? The weights are from the second half of July 2024, and INEGI chains the index: since then, whatever has risen most weighs a little more inside the basket. That is why the two can differ by a few hundredths.

The eight categories are the eight groups of INEGI’s classification by object of expenditure. Two things you might look for have no series of their own: school and fun go together («Educación y esparcimiento»), and there is no «other» category, because the eight groups cover the whole basket. Eating out is «Otros servicios»: almost all of its weight is loncherías, fondas, taco stands and restaurants.

What you learn here

  • The INPC measures the basket of the average household: food, housing, transport, services. Your own inflation can be higher or lower depending on what you actually buy.
  • Your inflation is the same calculation with your weights: each category’s official inflation times the share of your spending that goes there.
  • If most of your money goes to what rose the most, the official number will feel short, and you are not imagining it.

Educational tool. It assumes constant rates and ignores taxes, fees and any surprise; real returns and real inflation change every year. It is here to show the shape of the idea, not to plan your money with it, and it is not financial advice.
