Inflation Brief: April 2026

The Reality Index rose 4.61% year over year in April 2026, running about four-fifths of a percentage point hotter than the BLS headline CPI print of 3.81%. Since 1980, the Reality Index has risen 4.74× against CPI's 4.04× — a cumulative gap of 17.4%.

This edition restates the April brief on the Reality Index's current methodology — fixed 1980 expenditure weights, a tenure-weighted housing component, and published (sticker) tuition. It supersedes the figures in the original April brief; a separate methodology note explains the update in full.

The Reality Index — a fixed-weight measure of the prices American households actually pay across ten categories of everyday spending — rose 4.61% in April 2026 compared with April 2025. The BLS Consumer Price Index for All Urban Consumers (CPI-U), unadjusted, rose 3.81% over the same period. The Reality Index has now run ahead of the official measure in the large majority of months it covers.

What drove the print — category inflation, April 2026

Year-over-year change by category, with the Reality Index and official CPI all-items rates for reference

Reality Index all-items +4.61% vs official CPI +3.81%. Energy began to accelerate and vehicle prices diverged from CPI; communications remained the lone decliner.

What drove the print

Transportation rose 8.08% on the Reality Index transportation composite. Gasoline (BLS average pump price) was up 28.0% year over year — the leading edge of an energy move that would intensify in May — while used vehicles ran +3.3% at Manheim auction and new vehicles +1.8% at Kelley Blue Book, against quality-adjusted declines in the official vehicle indices.
Health care held a +5.56% year-over-year line, carried from the most recent KFF Employer Health Benefits Survey.
Utilities rose 5.39%, driven by the BLS energy-services subindex.
Housing — the single largest weight in the index — rose 4.30%. The renter portion, tracked via Zillow's ZORI rent index, ran +1.73% in April.
Communications continued its long-running decline (−1.99%), the only category whose price level sits below where it was a decade ago.

Groceries (+2.89%), dining out (+3.55%), education (+2.88%), pets (+2.72%), and discretionary spending (+2.34%) all printed in the low-to-mid single digits.

Why the Reality Index runs hotter than CPI

The Reality Index is built from BLS subindex data — the same source CPI draws on — with three deliberate departures: fixed 1980 expenditure weights, held constant rather than reweighted toward current spending; a custom tenure-weighted housing component combining the all-in cost of owning with the cost of renting; and health care priced from the KFF Employer Health Benefits Survey rather than the narrower BLS medical-care subindex. Tuition is carried at its published sticker price — what a school charges, before discounts or aid.

Reality Index vs official CPI — monthly readings

Year-over-year inflation rate by month (the monthly Reality Index series)

Year-over-year readings, March–April 2026. The Reality Index stayed above the official CPI as the spring energy surge began to close the monthly gap, from 1.05 points in March to 0.80 in April.

Cumulative context

Since 1980, the Reality Index has risen 4.74× against CPI's 4.04×. As of April 2026 that is a cumulative gap of 17.4% — the clearest single statistic for what the index is built to measure: the distance between what the official benchmark reports and what a fixed basket of everyday household costs has actually done.

Methodology notes

Weights. The Reality Index holds fixed 1980 expenditure weights across all years — a Laspeyres basket. It measures the cost of the same basket over time rather than reweighting toward how spending has shifted.

Housing. The housing bucket is tenure-weighted (roughly 65% owner / 35% renter, per the Census homeownership rate). In the current monthly edition the renter portion is refreshed via Zillow ZORI and the owner side is carried forward from the 2025 annual baseline; the full owner-cost model is documented at realityindex.co/housing.html.

Health care. The health-care bucket reflects the KFF Employer Health Benefits Survey, published annually each fall. Between releases it is carried forward at its most recent annual level.

Education. Education is priced at published (sticker) tuition. A net-of-financial-aid alternative is under consideration as a user-selectable scenario.

Transportation. Transportation is priced with a dedicated Reality Index composite: used vehicles at Manheim auction values and new vehicles at Kelley Blue Book transaction prices, gasoline at the BLS average pump price, and the remaining components from the matching CPI subindices. Vehicles are where the official index's hedonic quality adjustments make transaction prices diverge from CPI.
