We run a fast food deals site, so you'd expect us to tell you the drive-thru always wins. It doesn't. Here's the real per-meal math for one person in 2026 — and the hybrid strategy that actually minimizes your food budget.

The per-meal math, one person

ApproachCost per mealHidden costs
Fast food, full price$9–14The default everyone overpays for
Fast food, deal-stacked (this site)$4–6Requires the apps + checking daily deals
Groceries, batch-cooked basics$2–4Your time, dishes, and food waste if plans change
Groceries, cooking "whatever looks good"$6–10Single-serving cooking without a plan erases the savings

The truth: planned groceries beat even deal-stacked fast food on pure dollars. Rice, eggs, beans, pasta, frozen vegetables, chicken thighs — batch-cooked, that's $2–4 a meal. But the moment you cook without a plan, buy single servings, or throw out spoiled food, the advantage flips. For one person, food waste is the silent killer: Americans throw out roughly a third of the groceries they buy.

When fast food deals genuinely win

When groceries win

Grocery delivery: the deals side

Grocery apps run aggressive new-customer promos the same way restaurant apps do — typically $10–$20 off a first order or free-delivery trials from services like Instacart, plus digital-coupon stacking inside store apps. If you're doing the hybrid strategy, claiming one of these on your first big batch-cook shop is the same move as grabbing a fast food app's sign-up freebie: real money off, one time, no downside if you were buying anyway. As with every offer on this site, we only recommend claiming promos you'd actually use.

The hybrid strategy (what we'd actually do)

Batch-cook 8–10 cheap grocery meals a week (breakfasts + weekday dinners), then use verified fast food deals for the 4–6 meals where cooking wasn't happening anyway — late nights, campus days, Fridays when the fries are free. That's a realistic $180–250/month food budget for one person without eating sad.
