What Is Inflation and How Does It Affect Your Money?

Inflation is a sustained and widespread increase in the prices of goods and services over time. When prices rise faster than your income, each unit of money buys less than before; this is known as a loss of purchasing power.

Inflation does not mean that every price increases by the same percentage. Food, housing, transportation, energy, health care, and other services can change at different rates. For this reason, the inflation experienced by an individual household may differ from the national average.

How is inflation measured?

In Mexico, INEGI measures inflation using the National Consumer Price Index, which tracks changes in the cost of a representative basket of goods and services. The categories are weighted according to their importance in household spending.

For example, suppose a group of regular purchases costs MXN 1,000 today. After an illustrative price increase of 8%, the same purchases would cost MXN 1,080. When income remains unchanged, the household must reduce another expense, use savings, or find additional income to maintain the same consumption.

Why do prices rise?

Inflation can result from several factors:

• Demand grows faster than the economy’s ability to produce.
• Fuel, materials, transportation, or labor become more expensive.
• Natural disasters or supply disruptions reduce the availability of products.
• Expectations of future price increases influence contracts, wages, and business decisions.
• Excessive monetary expansion can create persistent pressure on prices.

The cause is not always the same, and several factors may occur simultaneously.

How inflation affects your finances

Your daily expenses increase. The same food, transportation, housing, and services require a larger portion of your income.

Cash savings lose purchasing power. The balance may remain unchanged, but it may purchase fewer goods over time.

Planning becomes more difficult. Uncertain prices complicate household budgets, business costs, wage decisions, and long-term goals.

Households are affected differently. Families that spend a larger share of their income on necessities may have less flexibility when food, housing, or energy prices rise. The World Bank has found that inflation can have unequal effects because households consume different combinations of goods and services.

Practical ways to adjust

1. Review your essential expenses and update your monthly budget.
2. Compare current prices instead of relying on older spending estimates.
3. Identify subscriptions and nonessential expenses that can be reduced.
4. Build an emergency reserve gradually.
5. Plan irregular expenses before they become urgent.
6. Review whether your income is keeping pace with your cost of living.
7. Avoid making rushed financial decisions based only on economic headlines.

Conclusion

Inflation affects more than prices: it changes what your income and savings can purchase. Understanding your personal spending patterns can help you adjust your budget and make more deliberate decisions.

Call to action: Compare your current essential expenses with those from three or six months ago and update your monthly budget.
