Coupon ROI calculator: size a campaign in seconds
Use sliders or number fields for fixed fee, expected incremental orders and average contribution per order. You immediately see rough incremental contribution and a ROI-style percentage – handy before seasonal peaks and event windows (conversion, returns and mix stay outside this simple model).

Costs you can clearly attribute to this coupon push – often a fixed portal fee.

The formula: what the calculator does
First we compute incremental contribution Z from your inputs: Z = (incremental orders × average contribution per order) − campaign budget. Then the ROI-style percentage is ROI = (Z ÷ campaign budget) × 100 when budget is greater than zero. That is a simple “return per euro spent” view on the modelled incremental contribution – not a full P&L, but a clear order of magnitude for coupon marketing and portal placements.
Benchmarks: what counts as a good ROI in e-commerce?
A “good” ROI depends on category, margin and channel mix. Useful guardrails include average order value, conversion rate and traffic uplift around shopping events – similar to the per-event benchmarks we show in the shopping events calendar (e.g. AOV benchmark, conversion benchmark, traffic uplift). Align coupon windows with real demand spikes (see the shopping events calendar in the related links below) and compare this calculator’s output with paid search, social and email, where cost and attribution patterns often differ from coupon sites.
Why a ROI view helps for coupon campaigns
Coupon properties aggregate high-intent queries (brand, voucher, discount intent). The key question is whether incremental demand justifies the spend. This tool is not a full P&L; it helps prioritise offer design, thresholds and run length – and whether to allocate budget to the coupon channel versus other acquisition levers.
Fixed fee instead of a CPO surprise
Classic networks scale fees with every redemption (cost per order). mioscoupon uses transparent packages: you know the channel line item up front – enter it as “campaign budget” and stress-test it against expected incremental orders.

Frequently asked questions about coupon ROI
- Which costs should I include for coupon marketing?
- Include all costs you can attribute to the campaign as “campaign budget” – for example the fixed placement fee on coupon portals, creative production, or exclusive codes used only for that channel. General shop overheads or internal staffing are usually excluded from this quick check but can be layered in a fuller P&L.
- Are fixed fees better than pure CPO (cost per order)?
- CPO rises with every redemption: strong campaigns become more expensive, which can complicate planning. Fixed fees make the budget predictable – use this calculator to see how many incremental orders you need for contribution to cover the fixed fee, then compare coupon marketing fairly with other channels that use fixed or variable billing models.
- Is the output legally or tax binding?
- No. The calculator is for fast orientation and to explain the underlying formula. For accounting, tax, discount law or contract design you still need your internal teams or professional advisors.
- How realistic are “incremental orders”?
- The number should reflect orders you attribute to the channel (incremental), not your entire shop volume. Use historic codes, tracking attribution (last-click vs. richer models) and seasonal benchmarks. Start with conservative assumptions and refine with live data.
