Social Security
The national inflation rate is an average, and your household is not average. A long commute makes gas prices bite harder; a big family feels grocery inflation first. Your personal inflation rate (PIR) is what the CPI would look like if it were built from your spending instead of everyone's, and it is the number that actually tells you whether your budget and savings are keeping up.

Key Takeaways
Inflation rates are in the double digits—for the first time in decades—driving up the cost of gas, food, and other necessities.
Inflation affects every individual differently, so calculating your own personal inflation rate can help you understand its effect on your lifestyle.
There are simple steps one can take to lessen the effects of inflation.

Understanding inflation and the Consumer Price Index
Inflation is the rate at which prices rise over time, and it is measured by the Consumer Price Index (CPI). After supply-chain disruption and energy shocks pushed the annual average to 8.0% in 2022, the highest in four decades, inflation cooled to 2.9% in 2024 and 2.6% in 2025. It has ticked back up in 2026, running around 3.4% as of mid-year, so "inflation is over" overstates it.
The Bureau of Labor Statistics builds the CPI from a weighted average of roughly 94,000 price quotes collected each month from stores, service providers, and rental units across the country. The published CPI is what the Social Security Administration uses to set the annual cost-of-living adjustment, which determines how much benefits rise the following year.
Average inflation rate in the United States
From 2012 through 2020, annual inflation rarely topped 2%. The pandemic and its aftermath changed that: the annual average jumped to 4.7% in 2021 from 1.2% in 2020, peaked at 8.0% in 2022, then fell back toward 2 to 3% by 2024 and 2025 before drifting up again in 2026.
Inflation rates by year (annual average CPI-U)
| Year | Inflation rate |
|---|---|
| 2012 | 2.1% |
| 2013 | 1.5% |
| 2014 | 1.6% |
| 2015 | 0.1% |
| 2016 | 1.3% |
| 2017 | 2.1% |
| 2018 | 2.4% |
| 2019 | 1.8% |
| 2020 | 1.2% |
| 2021 | 4.7% |
| 2022 | 8.0% |
| 2023 | 4.1% |
| 2024 | 2.9% |
| 2025 | 2.6% |
Figures are annual average CPI-U increases from the U.S. Bureau of Labor Statistics. The 2026 rate is still being tallied; check bls.gov/cpi for the latest 12-month figure.
Calculating your personal inflation rate
Your PIR reweights the CPI categories to match where your money actually goes. Someone older, in a different state, or at a different income level will get a very different number from the headline rate. Here is the process.
1. Categorize your spending
Pull a year of bank and credit card statements and sort every expense into categories that mirror the BLS categories:
- Food (groceries and dining out)
- Gas and motor fuel
- Shelter and utilities (rent or mortgage, electricity, gas, water)
- Transportation (car payments, insurance, transit fares)
- Medical care
- Apparel
- Recreation and entertainment
- Education
Put it in a spreadsheet with an annual total and a month-by-month view, and include a line for large once-a-year or once-a-quarter charges like an insurance premium.
2. Calculate your category weights
Divide each category's annual total by your total annual spending to get its weight as a decimal. If housing is 35% of your spending and gas is 10%, those weights are 0.35 and 0.10.
3. Look up the annual price change for each category
From the BLS category tables, find the 12-month percentage change for each of your categories. Say shelter rose 4.5% and gas fell 2%.
4. Multiply each weight by its category's price change
For each category, multiply the weight by the percentage change. Housing at a 0.35 weight and a 4.5% increase contributes 0.35 x 4.5 = 1.575 percentage points to your PIR.
5. Add up the category contributions
Sum every category's contribution from step 4. The total is your personal inflation rate for the past year.
6. Compare it to the national rate
Compare your PIR to the most recent 12-month CPI figure from the BLS (about 3.4% as of mid-2026, but use the current published number). If your rate is lower, inflation is hitting you less than the typical household. If it is higher, look at which categories are driving it and where you can adjust.
Caveats
This calculation misses anything you paid for in cash, and it does not capture the substitutions you are probably already making, buying on sale or driving less. Those things pull your real number down a bit, but the result should still be close enough to act on.
How to blunt the impact of inflation on your household
Once you know your PIR, a few moves help most when prices are rising faster than your income:
- Pay down variable-rate debt first, especially credit cards.
- Delay big discretionary purchases in categories that have jumped, like new cars or travel.
- Refinance an adjustable-rate mortgage to a fixed rate if the numbers work.
- Hold off on a second or vacation home.
- Ask for a raise if your employer has not adjusted pay for inflation.
- Revisit your retirement plan to see whether your assumed spending still holds, and whether your Social Security benefit and other income are keeping pace.
Final thoughts
Building the spreadsheet is tedious, but it converts a vague sense that "everything costs more" into a number you can budget against. If you want help checking that your savings can absorb a higher personal inflation rate now and through retirement, speak with a retirement planner.
