Calculate net happy hour revenue by multiplying discounted prices by volume and subtracting lost full-price sales. Evaluate promotion ROI.
Happy hours drive traffic during slow periods, but they also discount your highest-margin products — beverages. The key question every operator must answer is: does the incremental volume from happy hour pricing more than offset the revenue lost from guests who would have paid full price anyway?
This calculator helps you evaluate the financial impact of happy hour by comparing the revenue generated at discounted prices against the full-price revenue you sacrifice. The result is your net happy hour revenue — a realistic picture of whether the promotion is helping or hurting your bottom line.
Smart happy hour programs target truly incremental guests — people who wouldn’t visit without the discount — while minimizing cannibalization of regular full-price business. Understanding the math behind this trade-off is essential for designing promotions that genuinely grow revenue.
Restaurant owners, hotel managers, and event coordinators depend on accurate happy hour revenue numbers to maintain profitability while delivering exceptional guest experiences. Return to this tool whenever menu prices, occupancy rates, or staffing levels shift to keep your operations on track.
Many restaurants run happy hours without knowing whether they actually increase profit. By calculating net revenue — discounted revenue minus lost full-price sales — you get a clear answer. This data helps you set the right discount level, choose which items to discount, and determine whether happy hour is worth continuing.
Happy Hour Revenue = Discounted Price × Happy Hour Volume Lost Revenue = Full Price × Cannibalized Sales Net Revenue = Happy Hour Revenue − Lost Revenue
Result: $700 net revenue
Happy hour revenue: $6 × 200 = $1,200. Lost full-price revenue: $10 × 50 = $500. Net revenue: $1,200 − $500 = $700. The promotion generates $700 in net revenue, but only because 150 of the 200 happy hour sales are truly incremental.
The biggest risk with happy hour is cannibalization — guests who would have visited anyway simply shift their timing to capture the discount. If 100% of happy hour guests are cannibalized, the promotion is pure cost. The goal is to drive genuinely incremental visits. Track guest counts before and after implementing happy hour to measure incremental lift.
Beyond the direct revenue impact, happy hour serves as a low-cost marketing channel. It introduces new guests to your restaurant, builds a social atmosphere that attracts passersby, and fills an otherwise quiet period that still incurs fixed labor and overhead costs. Even break-even happy hours can be worthwhile for their marketing value.
Forward-thinking restaurants are replacing blanket discounts with more targeted promotions: industry nights, loyalty member exclusives, early-bird prix fixe dinners, and reverse happy hours (late-night discounts). These formats attract specific demographics while minimizing broad cannibalization of regular-priced service.
Calculate net revenue as this calculator does. If net revenue is positive and the promotion brings in guests who also order food or stay for dinner, it’s likely profitable. Factor in labor costs for the additional shift hours.
Discounts of 20-40% are typical. $2-$4 off drinks or half-price appetizers are common. Avoid discounting more than 50% — deep discounts attract deal-seekers who are unlikely to become regular full-price guests.
Compare sales during the happy hour window before and after implementing the promotion. The guests who were already buying at full price during that window represent your cannibalization estimate.
Discounting food (appetizers) while keeping drink prices full can work well because guests will order more drinks at full margin. Conversely, discounting drinks attracts traffic and the food they order covers the discount.
It depends on the format. Premium happy hours in upscale settings attract professionals looking for after-work options. Deep-discount happy hours in casual settings attract price-sensitive guests. Design your promotion for the clientele you want.
No. Some states and localities prohibit or restrict happy hours. Check local alcohol laws before launching any drink discount promotion. Some jurisdictions ban variable pricing on alcohol entirely.
