Incremental revenue is the extra revenue you generate from a specific marketing action, like a social media campaign. Many hospitality entrepreneurs don't know if their social media investment pays off. With the right calculation, you'll see exactly how much extra revenue your campaign generated.
What is incremental revenue?
Incremental revenue is the difference between your normal revenue and your revenue during a campaign. It's about the extra revenue you only have because you ran the campaign.
💡 Example:
Your restaurant normally does €8,000 per week. After an Instagram campaign for your new pastas, you do €10,500 that week.
Incremental revenue: €10,500 - €8,000 = €2,500
Determine your baseline revenue
Your baseline is your normal revenue without a campaign. This is crucial for accurate measurement.
- Take the average of 4-6 weeks before the campaign
- Exclude special weeks (holidays, events)
- Compare the same weekdays (Monday with Monday)
- Watch out for seasonal effects (summer vs. winter)
⚠️ Heads up:
Comparing a single week is unreliable. Weather, local events, or chance can skew your numbers. Always use multiple weeks.
Measure campaign impact
Track your revenue during and shortly after your campaign. Social media effects can carry over for 2-3 days.
- Record daily revenue during campaign period
- Monitor 3-7 days after the campaign (aftereffect)
- Watch which dishes sell more
- Check if new guests are coming (first visit)
💡 Example calculation:
Campaign for new burgers (5 days Instagram + Facebook):
- Baseline: €1,200/day average
- Campaign week: €1,650/day average
- Campaign costs: €280
Incremental revenue: (€1,650 - €1,200) × 5 days = €2,250
ROI: (€2,250 - €280) / €280 = 703% return
Correct for external factors
Not all extra revenue comes from your campaign. Other factors can play a role.
- Weather: Nice days attract more guests
- Events: Football match, festival nearby
- Competition: Competitor closed, renovations
- Season: Natural fluctuations
Compare with the same period last year to rule out seasonal effects.
Calculate the actual ROI
Return on Investment shows whether your campaign was profitable.
ROI formula:
(Incremental revenue - Campaign costs - Extra food cost) / Campaign costs × 100
💡 Complete ROI calculation:
Instagram campaign for weekly menu (€180 ad spend):
- Incremental revenue: €1,400
- Extra food cost (30%): €420
- Net profit: €1,400 - €420 = €980
ROI: (€980 - €180) / €180 = 444%
Track long-term effects
Good campaigns bring not only direct revenue but also new regular customers.
- Monitor new customers who return
- Check social media followers and engagement
- Measure revenue growth in weeks after campaign
- Record more online reservations
⚠️ Heads up:
Don't just measure revenue, but also profitability. A campaign that attracts lots of extra guests but pushes your food cost to 45% destroys your margin.
How do you calculate incremental revenue? (step by step)
Determine your baseline revenue
Calculate your average daily revenue from 4-6 weeks before the campaign. Exclude special days and compare the same weekdays. This becomes your reference point.
Measure revenue during campaign
Record your daily revenue throughout the entire campaign period. Also monitor 3-7 days after for aftereffects. Watch which dishes sell extra.
Calculate the difference
Subtract your baseline from your campaign revenue. Correct for external factors like weather or events. The result is your incremental revenue.
Determine the ROI
Subtract campaign costs and extra food cost from your incremental revenue. Divide by your investment and multiply by 100 for the ROI percentage.
✨ Pro tip
Track not just revenue, but also the number of covers during your campaign. If you do more revenue with the same number of guests, people are ordering more expensive items - that's often more valuable than just getting more guests.

Frequently asked questions
How long should I measure after a social media campaign?
Measure at least 3-7 days after your campaign. Social media effects often carry over because people share your posts or come back to them later. Some guests don't book a table until days later.
Should I include extra food cost in my ROI calculation?
Yes, absolutely. Extra revenue means extra ingredient costs. Calculate with your average food cost percentage to determine actual profit. Otherwise you'll overestimate your campaign results.
What if I run multiple marketing actions at the same time?
Then you can't attribute incremental revenue to one action. Plan campaigns separately or use tracking codes per channel to isolate the effect.
How do I know if new guests come from my campaign?
Ask new guests how they found you. Many restaurants do this at reservation or checkout. Rising social media followers are also an indicator.
Is a 200% ROI on social media campaigns good?
That's solid. Many hospitality campaigns achieve 150-400% ROI. Below 100% you lose money, above 300% is excellent. Just watch the long-term effects of new regular customers.
