Marketing ROI for restaurants: the only metric that tells you if your spend is working
What marketing ROI actually measures in a restaurant context, how to calculate it honestly, and how to fix a negative number.
A restaurant with a 4:1 marketing ROI and a 3:1 target is not in crisis. A restaurant with a 4:1 ROI and a 5:1 target is quietly bleeding on every marketing dollar. The number alone tells you nothing — the target does. And the target depends on your customer lifetime value: a restaurant with a 60% repeat rate can afford a lower ROI than one with a 20% repeat rate because the second visit is free.
The four channels and their honest math
- Social media: ROI is hard to attribute directly. Track cost per booking or cost per order, not cost per impression. A channel with a 5:1 ROI on bookings is worth keeping even if the impression-level ROI looks terrible.
- Email: the highest-ROI channel for most restaurants. Track revenue per send against cost per send. A 10:1 ROI is common for a well-segmented list.
- Local ads: track cost per footfall or cost per booking. A channel with a 4:1 ROI on bookings is worth keeping for a high-traffic location.
- Events and promotions: track incremental revenue, not total revenue. The revenue from a promotion is not all incremental — some of those customers would have come anyway.
A worked example
A restaurant spends €2,000/month on local ads. Attribution window: 90 days.
| Month 1 | €2,000 spend, €8,000 attributed revenue | 4:1 ROI |
|---|---|---|
| Month 2 | €2,000 spend, €6,000 attributed revenue | 3:1 ROI — at threshold |
| Month 3 | €2,000 spend, €4,000 attributed revenue | 2:1 ROI — below threshold |
| Action | Kill or restructure the channel | Two months below 3:1 is the trigger |
Two consecutive months below the 3:1 threshold is the trigger to act. Waiting for the third month means the channel has already bled more than the fix will save.
Making it stick
- 1Set the threshold. Pick a minimum ROI per channel. 3:1 for most channels, 5:1 for email, 4:1 for local ads. The number matters less than the commitment.
- 2Track per channel. Pull spend and attributed revenue for each channel monthly. Use a conservative attribution window.
- 3Flag channels below threshold. Any channel below threshold for two consecutive months gets flagged for investigation or kill.
- 4Fix or kill. A channel below threshold needs a structural change: new creative, new audience, new offer. If the structure is broken, kill it and reallocate to the channel above threshold.
FAQ
- What is a good marketing ROI for a restaurant?
- 3:1 minimum for most channels. Email can carry 5–10:1. Local ads need at least 4:1 to justify the spend. The right number depends on your customer lifetime value and repeat rate.
- How do I calculate marketing ROI honestly?
- Use (revenue from channel - cost of channel) / cost of channel. Use a conservative attribution window: 30 days for social, 90 days for email, 180 days for events. Track per channel, not in aggregate.
- What if my marketing ROI is below 3:1?
- Diagnose in order: attribution, creative, audience, offer. Fix the cheapest cause first. If the structure is broken (wrong audience, wrong offer), kill the channel and reallocate.
- Should I track marketing ROI monthly or quarterly?
- Monthly. A quarterly review catches a bleeding channel three months late. Monthly review catches it in the month it starts.
