What Is Inflation?
Inflation is the sustained, broad-based rise in the general price level of goods and services in an economy over time — and equivalently, the fall in the purchasing power of money. When inflation runs at 3% per year, a basket of goods that costs $100 today will cost $103 next year, $134 in a decade, and $243 in 30 years. Your dollar doesn't disappear, but it quietly buys less and less of everything you need.
In the United States, inflation is measured primarily by the Consumer Price Index (CPI-U) — the Consumer Price Index for All Urban Consumers — published monthly by the Bureau of Labor Statistics (BLS). The CPI tracks price changes across a weighted basket of goods and services reflecting the spending patterns of approximately 93% of the US population. As of February 2026, the annual US inflation rate stands at 2.4% (BLS release, March 11, 2026) — at its lowest level since May 2025, down from a peak of 9.1% in June 2022. Core inflation (excluding food and energy) is 2.5%.
Why inflation matters for every financial decision you make: Inflation is not just an abstract economic statistic — it directly determines whether your savings are growing or shrinking in real terms, whether your salary raise was actually a raise, whether your investment returns are real or illusory, and how much you truly need to save for retirement. A $1,000,000 nest egg in 2026 will have the purchasing power of only $744,000 in 2036 if inflation averages 3% — you need to account for this in every financial projection. The CatchyTools Inflation Calculator was built with five modes to make inflation's impact on your specific situation completely transparent and actionable.
What Is an Inflation Calculator — and What Should It Do?
A basic inflation calculator converts a dollar amount from one year to another using historical CPI data. After analysing the BLS official calculator, the Minneapolis Fed calculator, SmartAsset, NerdWallet, Calculator.net, and the US Inflation Calculator, one thing was clear: every existing tool does one thing well and misses four critical dimensions entirely. The CatchyTools Inflation Calculator was built to solve all five problems in one place.
Uses the full BLS CPI-U historical dataset from 1913 to 2026 to convert any dollar amount between any two years. Shows cumulative inflation, annual average rate, year-by-year equivalent values, and full CPI index data — the same underlying methodology used by the Federal Reserve and Bureau of Labor Statistics.
Projects what today's costs will be in any number of years under three simultaneous scenarios: a low scenario (2% Fed target), a base scenario (current 2.4% CPI), and a high scenario (elevated tariff-driven inflation). No other mainstream calculator models all three scenarios side by side with a year-by-year breakdown table.
The mode no other inflation calculator offers: compares your nominal salary change between any two years against the actual CPI change for that period, and tells you precisely whether your raise beat inflation or fell behind it — with the exact dollar amount you gained or lost in real purchasing power.
Shows how inflation destroys the real value of money sitting in low-interest savings accounts — and quantifies exactly how much a High-Yield Savings Account, CD, or Money Market Account would preserve compared to a standard savings account. Calculates real rates (interest minus inflation) year by year.
Enter your actual monthly spending across 8 categories, and we apply the real Feb 2026 BLS CPI rate for each category — shelter (3.0%), food at home (2.1%), healthcare (2.7%), education (4.1%), dining out (3.3%) — to calculate your personalised inflation rate and exact monthly cost impact. No other public calculator does this.
US Inflation — February 2026 Data
The annual inflation rate in the US held steady at 2.4% in February 2026, unchanged from January, remaining at its lowest level since May 2025. Stripping out volatile food and energy prices, the core CPI posted a 0.2% monthly reading and a 2.5% annual rate — in line with forecasts and unchanged from January, indicating that inflation was holding above the Federal Reserve's 2% target but not getting worse.
| CPI Category | 12-Month Rate (Feb 2026) | Monthly Change | Trend |
|---|---|---|---|
| All Items (Headline CPI) | 2.4% | +0.3% | Stable at lowest since May 2025 |
| Core CPI (ex food & energy) | 2.5% | +0.2% | Stable, near lowest since 2021 |
| Shelter / Housing / Rent | 3.0% | +0.2% | Slowing — rent +0.1% (lowest since Jan 2021) |
| Food (All) | 3.1% | +0.4% | Steady — eggs falling, coffee up 18% |
| Food at Home (Groceries) | 2.1% | +0.4% | Eggs down sharply; beef +15% |
| Food Away from Home (Restaurants) | 3.3% | +0.3% | Persistent labour cost pressure |
| Energy | 0.5% | +0.6% | Rebounding; oil price risk rising |
| Medical Care | ~2.7% | Stable | Long-term above-average trend |
| Education & Communication | ~4.1% | Stable | Tuition persistently elevated |
| Used Cars & Trucks | -3.2% | -3.2% | Deflation in used vehicle market |
| Apparel / Clothing | ~2% | +1.3% | Biggest monthly jump since Sep 2018 — tariff pressure |
Tariff risk and the inflation outlook for 2026: Economists warn that CPI inflation could rise to 3.5% by end of 2026 if oil prices remain elevated following recent geopolitical disruptions. Without the "tariff shock," the US inflation rate would likely be back to the Fed's 2% target. The average effective tariff rate reached 14.3% — the highest since 1939 — before recent legal challenges, and new equivalent tariffs have been introduced to maintain similar effective rates. Apparel prices saw their biggest monthly jump since September 2018 in February, a direct signal of tariff pass-through. For planning purposes, the CatchyTools Future Cost mode lets you model both the base (2.4%) and elevated (3.5–4%) scenarios simultaneously.
How the CPI Is Calculated — and Why It Matters
The Bureau of Labor Statistics collects approximately 80,000 price quotes monthly from thousands of retail outlets, rental units, medical offices, and service providers across 75 urban areas. These prices are combined into a weighted index where each category's weight reflects its share of average US consumer spending. The weights are updated annually using Consumer Expenditure Survey data — meaning the basket of goods changes over time to reflect actual spending patterns.
As of the latest BLS weighting (December 2025), the CPI categories and their approximate weights are: Housing/Shelter (~33%), Food (~14%), Transportation (~18%), Medical Care (~9%), Education & Communication (~7%), Recreation (~6%), Energy (~6%), and Apparel (~3%). The cumulative change in headline CPI since 2000 is 94.2% — meaning prices have essentially doubled since the year 2000.
CPI vs PCE vs Core — Which Measure Should You Use?
There are three main US inflation measures, each suited to different purposes. The CPI-U (this calculator's primary measure) tracks what urban consumers pay. The PCE (Personal Consumption Expenditures) price index is the Federal Reserve's preferred measure — it uses a broader spending base and allows for substitution effects, typically running 0.2–0.4% below CPI. Core inflation strips out food and energy, which are volatile, to show the underlying inflation trend. For personal financial planning and historical purchasing power calculations, CPI-U is the most relevant and widely used measure.
How to Protect Your Money Against Inflation
The fundamental rule of inflation protection is simple: your money must grow at a rate at least equal to inflation to maintain its purchasing power. If inflation is 2.4% and your savings account pays 0.5%, your real return is -1.9% — you are getting poorer in real terms every year. There are several financial tools that historically beat inflation across different time horizons and risk profiles.
| Option | Typical Rate (Mar 2026) | Real Rate vs 2.4% CPI | Best For |
|---|---|---|---|
| Traditional Savings Account | 0.1–0.5% APY | -1.9 to -2.3% real | Emergency fund minimum — switch to HYSA |
| High-Yield Savings Account (HYSA) | 4.5–5.0% APY | +2.1 to +2.6% real | Emergency fund, short-term savings |
| 12-Month CD | 4.5–5.2% APY | +2.1 to +2.8% real | Money you won't need for 12+ months |
| Money Market Account | 4.5–5.0% APY | +2.1 to +2.6% real | Liquid inflation-beating savings |
| I-Bonds (Treasury) | ~3.1% (Nov 2025 rate) | +0.7% real | Long-term inflation hedge; $10K annual limit |
| TIPS (Treasury Inflation-Protected) | CPI + 0.5–2.5% | +0.5 to +2.5% guaranteed real | Fixed-income inflation protection |
| S&P 500 (equities) | Avg 7% real historically | ~+4.6–7% long-term | Long-term wealth building (5+ year horizon) |
| Real Estate / REITs | Historically +2–4% real | +2 to +4% real | Inflation hedge with income |
The actionable short-term move most people overlook: The single easiest inflation protection available requires zero investing knowledge — simply move your emergency fund and short-term savings from a traditional bank account (0.1–0.5% APY) to a High-Yield Savings Account (4.5–5.0% APY). On a $20,000 emergency fund, the difference is approximately $900–$980/year in extra interest — with the same FDIC protection, same liquidity, and zero risk. Use the Savings Erosion mode above to see exactly what your current savings account is costing you in real purchasing power over time.

Frequently Asked Questions
Inflation is the rate at which the general level of prices for goods and services rises over time, reducing purchasing power. In the US, it is primarily measured by the Consumer Price Index for All Urban Consumers (CPI-U), published monthly by the Bureau of Labor Statistics (BLS). The BLS collects approximately 80,000 price quotes monthly from retail outlets, rental units, and service providers across 75 urban areas, then combines them into a weighted index reflecting the spending patterns of ~93% of the US population. The Federal Reserve also monitors the PCE (Personal Consumption Expenditures) price index from the Bureau of Economic Analysis, which tends to run slightly lower than CPI and is the Fed's preferred inflation gauge for setting monetary policy. The current US inflation rate is 2.4% (12 months ending February 2026, BLS release March 11, 2026).
The annual US inflation rate is 2.4% for the 12 months ending February 2026 (BLS CPI-U, released March 11, 2026) — unchanged from January and at its lowest level since May 2025. Core inflation (excluding food and energy) stands at 2.5%. Category highlights: shelter +3.0%, food +3.1% (groceries +2.1%, restaurants +3.3%), energy +0.5%, used cars -3.2%. The next BLS CPI release, covering March 2026, is scheduled for April 10, 2026. Economists warn of potential upside risk from elevated oil prices and ongoing tariff impacts — with some projecting CPI could reach 3.5% by year-end under adverse scenarios.
To calculate the inflation-adjusted (real) value of an amount from one year to another, you need the CPI values for both years. The formula is: Adjusted Amount = Original Amount × (CPI in Target Year ÷ CPI in Base Year). For example, to find what $10,000 in 2010 is worth in 2026: CPI 2010 = 218.1, CPI 2026 ≈ 330.8. So: $10,000 × (330.8 ÷ 218.1) = $15,169. This means $10,000 in 2010 had the same purchasing power as $15,169 in 2026 — a cumulative inflation of 51.7% over 16 years. The Purchasing Power mode in this calculator does this calculation automatically for any pair of years from 1913 to 2026 using full BLS CPI data.
The long-run average US inflation rate from 1913 to 2024 is approximately 3.27% per year, according to BLS CPI-U data. However, this average masks enormous variation: the 1970s saw double-digit inflation peaking at 13.5% in 1980, while the 1950s–1960s averaged around 1–3%. More recently, inflation averaged around 1.8–2.3% from 2009–2019, then spiked to 8.0% in 2022 following COVID-19 supply disruptions and energy price shocks. The 2022–2025 disinflationary period has brought inflation back toward 2.4%, closer to the Fed's long-run 2% target. For long-term financial planning, most financial advisors use 2.5–3% as a reasonable central estimate for future US inflation.
If your savings account interest rate is lower than the inflation rate, your money is losing real purchasing power every year — even as the nominal dollar amount grows. A traditional savings account paying 0.5% when inflation is 2.4% delivers a real return of -1.9% per year. Over 10 years, $50,000 in such an account would have the real purchasing power of approximately $40,900 — a loss of $9,100 in real terms even though your nominal balance is higher. The solution is simple and risk-free: High-Yield Savings Accounts currently offer 4.5–5.0% APY — well above inflation — providing a positive real return of +2.1 to +2.6%. The Savings Erosion mode in this calculator models this exact impact year by year and shows the dollar difference a HYSA would make.
Core inflation is CPI calculated without food and energy prices. The Federal Reserve and most economists use core inflation as their primary gauge of underlying inflation trends because food and energy prices are highly volatile — driven by weather, geopolitical events, and commodity market cycles — and these short-term swings can obscure the true direction of broad price pressures. For example, a cold snap raises natural gas prices sharply for a month, making headline CPI spike; but this doesn't mean the underlying economy is more inflationary. Core inflation (2.5% in Feb 2026) reflects the persistent, harder-to-reverse price trends in services, rent, healthcare, and wages that the Fed can actually influence through interest rate policy. That said, for personal financial planning purposes, headline CPI is usually more relevant because you actually pay for food and energy every month.
To determine whether your raise beat inflation, compare your percentage salary increase to the cumulative CPI inflation over the same period. If you earned $65,000 in 2020 and now earn $78,000 in 2026, your nominal increase is 20%. But CPI rose approximately 26% from 2020 to 2026, meaning you needed to earn $81,900 in 2026 just to maintain the same purchasing power as $65,000 in 2020. In this example, your real salary has actually fallen by about 4.8% despite the nominal raise. The Salary Check mode in this calculator does this analysis automatically — you enter your salary in both years, select the years, and it tells you your precise real gain or loss and whether you beat or lost to inflation.
Inflation has three main causes. Demand-pull inflation occurs when consumer demand outpaces supply — too much money chasing too few goods. Cost-push inflation occurs when production costs rise (labour, energy, raw materials), pushing prices higher even without demand increases. Built-in (wage-price spiral) inflation occurs when workers expect higher prices and demand higher wages, which businesses pass through as higher prices, reinforcing the cycle. The 2021–2022 US inflation spike combined all three: COVID supply chain disruptions (cost-push), massive fiscal stimulus ($5T+ in emergency spending), and tight labour markets. The Federal Reserve's primary tool is the federal funds rate — raising rates makes borrowing more expensive, cooling demand and reducing inflationary pressure. The Fed raised rates aggressively from 0.25% to 5.5% between 2022 and 2024, successfully bringing inflation from 9.1% to the current 2.4% range.
Inflation is arguably the most underestimated risk in retirement planning. A 3% annual inflation rate means prices double every 24 years — so a retiree at 65 planning to age 90 faces prices that are 2× today's by their mid-80s. To account for this: first, use an inflation-adjusted return assumption when projecting your portfolio (7% nominal – 3% inflation = 4% real return is the standard approach). Second, ensure your withdrawal rate accounts for annual cost-of-living increases — the 4% rule already builds in inflation adjustments. Third, consider inflation-protected income sources: Social Security COLAs (2.5% in 2026), TIPS, and I-Bonds. Fourth, maintain some equity exposure in retirement (a 60/40 portfolio has historically outpaced inflation over 20-year periods). The CatchyTools Retirement Savings Calculator models inflation explicitly in every projection — use it alongside this calculator for a complete retirement planning picture.
