About What Things Cost
“Gas was 89 cents when I was born” is the kind of fact people repeat for decades — usually slightly wrong. This tool does it properly: your birth year against actual government price series — BLS average prices for gas, eggs, bread, coffee, milk and electricity, the CPI back to 1913, the DOL minimum wage, the Census median new house, and the USPS’s own stamp history (including 2016’s genuine price decrease, preserved because it happened).
The shareable line is the multiplier: your birthday $20, converted to today by the official index — and the share card carries your year, the multiplier and the gas price that makes people gasp. Rows before a series existed say so honestly instead of inventing a number.
The classic use: a parent’s salary. “$30,000 in 1985” converts to its modern equivalent — often the moment the past stops sounding cheap.
How to Use What Things Cost
Enter your birth year and take the trip. The receipt shows what the staples actually cost that year — annual averages from the government series that measured them — against the latest published month, with each row labelled by its source and its honest starting date. The headline is the CPI conversion of a birthday $20; the share card carries your year, the multiplier, and the gas price.
Reading the Receipt Like an Economist
Three patterns hide in the table. Groceries roughly track the CPI over long stretches — eggs spike and crash (avian flu years are visible) but revert. Energy swings hardest: gasoline can double and halve within a decade. And the two rows that define the affordability conversation move in opposite directions: the median new house has beaten inflation for sixty years, while the federal minimum wage — $7.25 since 2009 — has quietly lost about a third of its purchasing power to it. Your birth year decides which side of those curves your nostalgia lands on.

Sources per row: BLS Average Price series and CPI (via FRED), Census/HUD median new-house price, DOL federal minimum wage, USPS published rate history. Annual averages; the “now” column is the latest published observation with its date shown. City-average national figures — your grandmother’s corner store may have differed, and she knows it.
Frequently Asked Questions
Where do these prices come from?
Real series, each labelled on its row: the BLS Average Price series for groceries, gasoline and electricity (published monthly since the late 1970s), the Consumer Price Index back to 1913, the federal minimum wage from the Department of Labor, the median new-house price from the Census/HUD survey (since 1963), and the USPS's own first-class rate history. Everything is annual averages of actual published data — no "adjusted estimates", no folklore prices.
Why do some rows start later than my birth year?
Because we refuse to fake it. The BLS began publishing average grocery prices in 1980, gasoline in 1976, milk's modern series in 1996 — before those dates the row honestly says "series begins in…" rather than inventing a number. The CPI multiplier always works (1913 onward), so your birthday-dollar conversion never goes missing even when the egg price does.
What does the "×3.0" multiplier actually mean?
It's the ratio of today's Consumer Price Index to your birth year's — the official measure of how far a dollar has stretched thin. ×3.0 means the average basket of consumer goods costs three times what it did; equivalently, $20 in your birth-year pocket bought what $60 buys now. It's an average across everything — individual items drift differently, which is exactly what the table shows.
Why did houses outrun everything else?
The table makes the divergence visible: since 1963 the CPI rose roughly 10-fold while the median new house rose about 24-fold. Houses got bigger (average new-home square footage nearly doubled), land near jobs got scarcer, and building slowed after 2008 — the median price mixes all three with pure inflation. It's the cleanest one-row explanation of why "my parents bought a house on one salary" stings.
A stamp cost MORE in 2016 than 2017?
Yes — genuinely. The USPS raised first-class postage to 49¢ in 2014 under a temporary surcharge, and when it expired in April 2016 the price DROPPED to 47¢ — the first decrease in nearly a century — before resuming its climb in 2017. The rate table preserves the dip because it really happened, and because a price series with no surprises is usually a fabricated one.
