Formula used
- Total cost = sum of all campaign cost fields.
- Credited revenue = Attributed revenue + Assisted revenue × Assisted weight.
- Net revenue = Credited revenue × (1 − Returns rate).
- Gross profit = Net revenue × Gross margin.
- Net profit = Gross profit − Payment fees − Overhead − Total cost.
- ROI (%) = (Net profit ÷ Total cost) × 100.
- ROAS = Net revenue ÷ Total cost.
- CPC = Total cost ÷ Clicks. CPA = Total cost ÷ Orders.
- Break-even net revenue = Total cost ÷ (Gross margin − Fees − Overhead).
- LTV-adjusted ROI adds estimated future gross profit from new customers.
How to use this calculator

- Select an attribution model, or use Custom for your weight.
- Set margin, returns, and payment fees to estimate true profit.
- Optionally add clicks, orders, and new customers for efficiency metrics.

Separate fixed and variable influencer costs
List every cost line the calculator supports: creator fee, seeding, shipping, production, paid amplification, platform fees, agency cost, tools, and overhead. Fixed costs (fee, production) stay constant, while variable costs (seeding units, paid spend) scale. In many ecommerce campaigns, seeding plus shipping add 8–20% of the creator fee, and paid amplification can match the fee when you boost winners.
Translate tracked sales into credited revenue
Use attributed revenue for sales proven by tracking links, promo codes, or surveys. Add assisted revenue for halo effects like branded search lift and repeat visits. The calculator applies an assisted weight to turn this into credited revenue. If your reporting is last-click heavy, 0.15–0.30 is common; for discovery-first creators, 0.35–0.60 may fit better.
Profit-first ROI beats ROAS for planning
ROAS is useful, but profit pays bills. After returns, margin, and payment fees, a 2.0 ROAS campaign can still lose money if margin is 35% and returns are 18%. Enter gross margin and fees to get net profit, ROI, and break-even net revenue. If (margin − fees − overhead) falls below 25%, you need higher credited revenue or lower total cost.
Attribution choices change decisions fast
Attribution settings can change the story fast. A $10,000 campaign with $18,000 attributed and $10,000 assisted revenue yields $19,500 credited at 0.15 weight, but $24,000 at 0.60 weight. That swing can flip ROI from negative to positive. Pick one model for weekly reporting, and change only when your tracking rules change or you run controlled tests.
Benchmarks to validate your inputs
Sanity-check inputs with benchmarks. Payment fees often sit near 2.5–3.5% plus a small fixed charge, and return rates commonly range from 5–25% by category. If clicks are available, compare CPC to your paid social average; if orders are tracked, compare CPA to your blended target. Add new customers and repeat purchase factor to model LTV upside. For subscription or refill items, use conservative repeat factors (1.2–1.6) unless cohorts prove retention. Track discount leakage by separating full-price and code-driven orders over time carefully.
FAQs
What revenue should I enter when using discount codes?
Enter the net sales value you credit to the code, before returns. If the code stacks with other promos, use the post-discount order value. Keep returns rate realistic so net revenue reflects refunds and cancellations.
How do I choose an assisted weight?
Start with your analytics standard. If you report last-click, use 0.15–0.30. If creators drive top-of-funnel discovery and you see search lift, test 0.35–0.60. Keep the same weight across periods for fair comparisons.
Does ROI include product cost of goods?
Yes, indirectly. Set gross margin to reflect product cost, pick/pack, and variable fulfillment. The calculator uses margin to estimate gross profit, then subtracts costs to reach net profit and ROI.
What if I run multiple influencers in one campaign?
Add all costs and revenues into one run to view blended ROI. For better control, run the calculator once per creator and compare ROI, CPA, and break-even revenue side by side before reallocating budget.
Why does my ROI look negative while ROAS is above 1?
ROAS compares net revenue to cost, but ROI depends on profit. High returns, low margin, large fees, or heavy overhead can erase profit even when revenue exceeds spend. Adjust margin and returns to match your store reality.
When should I use the LTV-adjusted ROI?
Use it when you can estimate new customers reliably. Enter new customer count, average gross profit per customer, and a repeat factor. Keep the factor conservative unless cohort data shows repeat purchases and retention.
