On May 1st, I finally caved. I’d been watching gas prices tick up for weeks, telling myself every few days that they’d have to come back down soon. They didn’t. The national average blew past $4.00 in early April — the first time since 2022 — and kept going, driven by disruptions in the Strait of Hormuz. By the time I pulled into our local Costco on a Thursday morning, I was running on fumes and out of excuses. I pumped 17 gallons and paid $75.09. I texted my husband a photo of the receipt. I don’t think I’ve ever spent that much on a tank of gas in my life.

I’ve been tracking our household spending since 2006. Every fill-up, every year, logged in Quicken. So naturally, the $75 receipt sent me straight to the data. I wanted to know: has gas actually gotten dramatically more expensive over our lifetime — or does it just feel that way every time prices spike?

The answer surprised me. And the more interesting story turned out to be one I hadn’t even thought to look for.

A Brief Detour to 2001

I started driving in 2001. Gas was already cheap by historical standards, but then a new station opened in our small town and a price war broke out. For a couple of glorious weeks, I was filling up for $0.99 a gallon. The whole town was talking about it. As a 16-year-old with a part-time job, it felt like a genuine gift.

To be fair about the comparison: $0.99 wasn’t a normal price — it was a price war anomaly, and treating it as a baseline would be cheating. The actual national average in 2001 was around $1.46 a gallon. Adjusted for inflation, that’s about $2.64 in today’s dollars. Current prices at $4.39 to $5.00 are genuinely more expensive than 2001 in real terms — just not by the absurd margin my $0.99 memory implies.

That said, “more expensive than the early 2000s” turns out to be almost the only version of the story that holds up. The picture from my own records since 2007 tells something quite different.

What the Data Actually Shows

I’ve been tracking our fuel spending since 2006 — the year we got married. Not estimates. Not averages based on how often I think I fill up. Actual transaction records, month by month, in Quicken for nineteen years.

In 2007 — our first full year of data — we spent $2,861 on fuel. In 2025, we spent $2,332. That’s right: in nominal, face-value dollars, we spent less on gas last year than we did eighteen years ago. Despite driving a larger vehicle. Despite gas being at a higher price per gallon. Despite everything.

But the more striking number is what happens when you adjust for inflation. $2,861 in 2007 is worth about $4,416 in 2025 dollars. Our actual 2025 fuel spending was $2,332. That’s a 47% drop in real spending — nearly half as much, inflation-adjusted — from where we started.

Two things explain this, and they work together in a way I hadn’t fully appreciated before pulling the data.

First: gas prices have genuinely lagged general inflation. The national average in 2007 was about $2.80 a gallon. Adjusted for CPI inflation, that should be $4.32 in today’s money. The 2025 annual average was around $3.42 — a full 21% cheaper in real terms than 2007 gas, despite all the headlines about expensive energy. Gas is one of the few things you buy regularly that has actually gotten cheaper in real terms over the past two decades — until, potentially, right now in 2026.

Second — and honestly this turned out to be the bigger story — we’re buying a lot fewer gallons than we used to.

The Miles We’re Not Driving

My best estimate, based on what we spent divided by the national average price per gallon each year, is that we bought around 1,022 gallons of gas in 2007. Last year, that same math produces about 682 gallons. We’re buying roughly a third fewer gallons than we were eighteen years ago. That’s the real story.

I can explain almost all of it in three chapters.

Chapter one: the long-distance years. From 2007 to 2018, we lived about three hours from both sets of parents. We made that drive probably six to eight times a year — holidays, summer visits, just because. Add in that we were both working or in school, commuting daily, and you get a household that was genuinely putting miles on two cars. Our highest fuel year was 2018 at $3,730 — both cars in regular use, husband with his longest commute ever, the three-hour drives still happening.

Chapter two: the move that changed everything. In 2018, we relocated to a town ten minutes from my husband’s office and twenty-five minutes from our parents. Overnight, the math of our driving life changed completely. The three-hour drives disappeared. The long commute disappeared. Our 2019 fuel spending dropped to $2,369 — a 37% single-year decline — before COVID even arrived.

Chapter three: 2020 and the commute that never came back. In 2020, our fuel spending fell to $1,428 — a 40% drop from the year before, and our all-time low. That’s COVID and the shift to remote work landing simultaneously. My husband went from driving to an office most days to working from home at least half the time. We joke that he’ll drive his Audi for another twenty years at the rate he puts miles on it. The Honda Pilot is definitively the family car now — we take it everywhere, and he drives the Audi twice a week if that.

His driving has never recovered. I don’t think it will. And our fuel spending reflects that precisely.

So Why Does It Still Sting at the Pump?

Because sticker shock is real even when the annual math works in your favor. When I stood at that Costco pump on May 1st watching the total tick past $60, then $70, then finally stop at $75.09, the number landed hard regardless of what my spreadsheet says about long-term trends. A $75 fill-up is a visceral experience. The data doesn’t make that feeling go away.

And I want to be honest: 2026 is genuinely different. The current spike isn’t a normal price fluctuation. The national average broke $4.00 for the first time since August 2022 in early April and hit $4.45 — a record for that calendar date — by the start of May. That’s up more than $1.25 from a year ago, driven by ongoing Middle East supply disruptions. Analysts are talking about $5-a-gallon gas by Memorial Day as a realistic scenario. Our local Costco was the cheapest option around when I filled up, and the surrounding stations were at or above $5.00. So the pain is real, even if my nineteen-year average says something different.

What keeps me from actually worrying about it, though, is the math of our own situation. Even at $4.39 a gallon, with the miles we drive now, we are not a high-fuel household. If prices stabilize around $4.50 for the rest of the year and our gallon estimates hold steady, our 2026 fuel spending might land around $3,000 — noticeably up from 2025, but still below every year from 2017 through 2019 when gas was cheaper and we just drove more. The gallons matter as much as the price.

Honestly? My bigger concern right now is marine gas. We’re members of a boat club — we use the boats, and we pay for the fuel we put in them. Marine fuel prices run higher than pump prices under normal conditions. At $5-a-gallon gas and beyond, a day on the water starts to get expensive fast. We’ll be getting out on the water in a few weeks and finding out exactly what this summer costs us at the dock. That’s a first-world concern and I fully acknowledge it — but if you’ve ever watched a marine fuel meter run, you understand why I’m watching this situation more nervously than the pump at our local gas station.

The Full 19-Year Record

What I’ve Learned from 20 Years of Fill-Ups

The price per gallon matters less than how many gallons you buy. This sounds obvious, but I hadn’t really sat with it until I looked at the full data set. Our highest-spending fuel years were not our highest-price years — they were our highest-mileage years. 2018 had $2.64 gas and we spent more than any other year in our history. 2022 had $3.97 gas and we spent less than 2018. Because we drove less. The pump price is only half the equation.

Your address is a fuel budget decision, even if you never think of it that way. Moving ten minutes from my husband’s office and twenty-five minutes from our parents cut our fuel spending by more than any car upgrade or driving habit change could have. We weren’t optimizing for transportation costs when we chose where to live. But the data doesn’t care about our reasons — it just shows the outcome.

Gas has been a pretty good deal by historical standards — until now. Over the full 18-year window, a gallon of gas has gotten cheaper in real terms, not more expensive. The $2.80 we paid in 2007 is $4.32 in today’s money. For most of that period, actual pump prices stayed well below that. 2026 is the exception, not the rule — and whether it stays an exception depends entirely on what happens in the Middle East.

The sticker shock and the annual math can both be true at once. $75 for a tank of gas is jarring. It should be. That doesn’t mean your household fuel budget is in crisis — it means one transaction hit you harder than usual. Looking at the annual number, not the per-fill-up number, is where the real picture lives.

I’ll be watching our 2026 fuel spending with more interest than usual. And I’ll be watching the marina prices even more closely. Some first-world problems are still problems.
