This tool shows the break-even volume requirement — it does not predict whether a promotion will actually drive that much extra demand. Pair it with historical response data from past promotions where possible.
How it works
Formulas used
Baseline monthly profit = Baseline profit/order × Baseline monthly orders Required promotional orders = Baseline monthly profit / Promo profit per order Required uplift % = Required promotional orders / Baseline orders − 1
Worked example
$22 baseline profit/order, $16 promotional profit/order, 200 baseline monthly orders:
- Baseline monthly profit: 200 × $22 = $4,400
- Required promotional orders: $4,400 ÷ $16 = 275 orders
- Additional orders needed: 275 − 200 = 75, a +37.5% volume uplift

Frequently asked questions
What if my promotional profit per order is zero or negative?
No amount of extra volume can compensate — the calculator will tell you this directly rather than showing a misleading number.
Separate break-even volume from a sales forecast
The required uplift tells you how much more volume is needed to preserve profit after a promotion. It is a hurdle rate, not evidence that demand will actually increase by that amount.
Use the hurdle rate
- Compare the required uplift with results from similar campaigns and channels.
- Model conservative, expected and optimistic order counts before committing spend.
- Include capacity limits so operational bottlenecks are visible in the decision.
What the number omits
- Incremental ad spend can erase profit even when sales volume reaches break-even.
- Orders from existing customers may not represent incremental demand.
- Returns, cancellations and stockouts can lower realized campaign volume.
