How to Convert Oven Recipes to Air Fryer
This calculator compares average U.S. grocery prices from January 2020 (pre-pandemic) to current 2026 prices for common items, letting you build a personalized basket to see your actual inflation impact.
The basic rule:
- Prices are based on USDA and BLS average retail price data for urban consumers
- Your personal inflation rate is calculated as: ((2026 basket - 2020 basket) / 2020 basket) × 100
- Annualized inflation rate uses the compound formula over 6 years to show average yearly increase
- Regional prices vary — these are national averages. Your local prices may be higher or lower
Official CPI food inflation was about 25% cumulative from 2020-2026, but individual experiences vary widely based on what you buy and where you shop. Some items like eggs saw 100%+ increases while others remained relatively stable.

Frequently Asked Questions
Why have grocery prices increased so much since 2020?
Multiple factors: supply chain disruptions from COVID-19, avian flu devastating egg production, increased energy and transportation costs, labor shortages, corporate profit expansion (so-called 'greedflation'), increased input costs for farmers, and general monetary inflation from pandemic-era stimulus spending.
Which groceries have increased the most?
Eggs saw the largest increase (100%+ at peak), followed by butter (40%+), beef (35%+), and bread (30%+). Fresh fruits and vegetables saw moderate increases (15-25%). Some items like rice and pasta saw smaller increases (10-20%) as supply chains normalized.
Is food inflation slowing down in 2026?
Year-over-year food inflation has moderated to 2-4% annually in 2025-2026, down from peaks of 11%+ in 2022. However, prices have not decreased — they've simply stopped rising as fast. The cumulative impact from 2020 remains significant for most households.
How does my personal inflation rate compare to official CPI?
Official CPI uses a fixed basket with substitution adjustments. Your actual experience depends on what you buy. Households that consume more eggs, meat, and dairy likely experienced higher-than-official inflation. Those who eat more grains, frozen foods, and store brands may be closer to or below official figures.
How can I reduce my grocery spending?
Top strategies: switch to store brands (20-30% savings), buy seasonal produce, use loyalty programs and digital coupons, buy in bulk for non-perishables, reduce food waste (average family wastes $1,500/year), meal plan, and consider discount grocers like Aldi or WinCo.
Will grocery prices ever go back to 2020 levels?
Extremely unlikely. Deflation (falling prices) is rare and historically only occurs during severe recessions. What typically happens is that wages eventually catch up to prices, restoring purchasing power — though this process can take years and doesn't help those on fixed incomes.
