Welcome to Issue 2 of The Receipt, a recurring market insights series from Affinity Solutions that takes a focused look at consumer spending trends drawn from over 150 million U.S. credit and debit cards representing 100 M+ consumers. Each edition examines a specific moment, category, or behavioral shift to translate verified purchase activity into actionable insights for brands, agencies, and media partners.
The burger wars are sizzling. Restaurant Brands International just announced its Q2 earnings showing Burger King posting its fifth straight quarter of U.S. sales growth. Burger King’s same-store sales jumped 8.5% in the quarter ending June 30, easily beating analyst expectations, powered by a revamped Whopper and a Star Wars-themed promotional run that pulled in incremental traffic. McDonald’s, meanwhile, told a more complicated story in its own Q2 report: net income was up, but U.S. same-store sales grew just 0.8% with customers spending more per visit, but visiting less often, and the company named a new president of McDonald’s USA.
Read as two news headlines, it looks like Burger King is closing the gap. Read against 18 months of real transaction data, the picture looks different and is more useful for anyone making a bet on either brand.
We analyzed transaction-level spending data from January 2025 through June 2026 across both brands’ U.S. customer bases. The short version: Burger King is indeed winning the argument about menu and momentum. But don’t count McDonald’s out. They still win the argument that matters more: total customer value.
The Premium Burger King Has Always Had
Burger King customers spend more per visit. Our data shows a 16% premium: $15.01 per transaction at Burger King versus $12.89 at McDonald’s. And it holds up almost everywhere we looked. Across every income bracket, from under $20K households to $151K+, the Burger King premium sits in a tight $2.00–$2.08 band. Across every age group, it ranges from $1.84 to $2.67, widest among 18-24 year-olds.
This isn’t an affluence story or an age story. It’s a pricing and menu story, and it’s been true well before this year’s Whopper relaunch.
The Gap Burger King’s Growth Quarter Doesn’t Touch
Here’s what the ticket-size premium can’t offset. McDonald’s customers visited 18.8 times over the 18-month window (roughly once a month). Burger King customers visited 5.8 times (roughly once a quarter). That’s a 3.2x frequency advantage for McDonald’s, and it’s consistent across age groups: 18-44 year-olds visit McDonald’s about 3.5x more often than Burger King, and even McDonald’s least-frequent segment (65+, at 16.4 visits) still visits more than 2.5x as often as Burger King’s most-frequent one.
It’s the bartender’s math: the regular dropping $5 a week beats the big spender who shows up once a quarter and drops $50. Over 18 months, the average McDonald’s customer was worth $242.43 in total spend. The average Burger King customer was worth $87.21.
Why Demographics Don’t Explain Any of It
Age and income don’t explain either gap. The Burger King ticket premium is nearly identical across every income bracket; the McDonald’s frequency advantage shows up in every age group, strongest of all among middle-income households ($41K–$80K).
A better explanation for the gaps is brand positioning and habit: Burger King’s premium comes from menu pricing, not affluence; McDonald’s frequency comes from routine, not any particular customer segment.
What a Good Quarter Can’t Buy
None of this means Burger King’s quarter wasn’t real. An 8.5% comp-sales jump on the back of a menu relaunch and a limited-time promotion is a legitimate result, and it’s the kind of move that can lift ticket size or pull in a one-time visit. It’s much harder for a single promotion to convert an occasional customer into a habitual one. Our data shows that’s exactly where the 18-month gap with McDonald’s lives. A limited-time offer can move the $15.01 number for a quarter. It’s a different, slower project to move the 5.8.
That’s also the opening in McDonald’s Q2 numbers. Traffic declined even as spend per visit rose. This could signal that the habit McDonald’s has spent years building may be loosening at the edges, even if it hasn’t broken. With a new head of McDonald’s USA now in place, the frequency advantage this data confirms is the asset most worth protecting, and testing selective pricing against a customer base this loyal is a very different conversation than testing it against Burger King’s.
The Takeaway
Earnings headlines are built around a single quarter. Customer relationships are built (and lost) over many more than that. Our Consumer Purchase Insights show a McDonald’s customer base that is bigger, more frequent, and worth nearly three times as much per person, and a Burger King customer base that pays more per visit but shows up a quarter of as often. Both patterns held steady long before this quarter’s news cycle, which is exactly why they’re worth watching as the two brands’ next few quarters play out.
This is the kind of view that consumer purchase insights make possible that earnings calls alone can’t: not just what happened last quarter, but which customer behaviors are actually durable. If you’re evaluating brand health, competitive share, or customer loyalty in restaurants or any other category, that’s the lens Affinity Solutions builds for because we are what happens.
