Example Data Table

Scenario	Inputs	Key outputs
Sample Search Campaign Good for quick benchmarking.	Budget: $1,000 CPC: $1.50 CTR: 2.5% CVR: 4.0% AOV: $80 Margin: 30%	Clicks: ~666.67 Conversions: ~26.67 Revenue: ~$2,133.33 ROAS (media): ~2.133x Break-even CPC: ~$0.9600

Numbers are illustrative. Real performance varies by audience, creative, landing page, and attribution.

Formula Used

Clicks = Spend ÷ CPC (budget mode)
Clicks = Impressions × (CTR ÷ 100) (impressions mode)
Impressions = Clicks ÷ (CTR ÷ 100) (when CTR > 0)
Conversions = Clicks × (CVR ÷ 100)

Value/Conversion = AOV × Multiplier × (1 − Refund%)
Revenue = Conversions × Value/Conversion
Gross Profit = Revenue × (Margin ÷ 100)
Total Cost = Spend + Fees + TaxOnFees + OtherCosts
ROAS = Revenue ÷ Spend
ROI% = (Net Profit ÷ Total Cost) × 100
Break-even CPC = Value/Conv × Margin × CVR (as fractions)

FAQs

1) What is included in “total cost”?

Total cost includes media spend, percentage fees, fixed fees, tax/VAT applied to fees, and any extra cost per conversion you enter.

2) Why are there two ROAS numbers?

Media ROAS uses revenue divided by ad spend only. All‑in ROAS uses revenue divided by total cost, which includes management fees and other non-media expenses.

3) What does “value multiplier” mean?

It scales revenue per conversion. Use 1.0 for single-purchase value, or a higher number to approximate lifetime value from repeat orders or subscriptions.

4) How is break-even CPC calculated?

Break-even CPC estimates the maximum CPC that yields zero net profit per click, based on value per conversion, gross margin, and conversion rate.

5) Can I use this for lead generation?

Yes. Treat AOV as your expected lead value and set margin to the portion you keep as gross profit. Add other per-conversion costs for sales follow-up or onboarding.

6) Why is CPA shown as N/A sometimes?

CPA requires conversions. If conversion rate is zero or the calculation produces zero conversions, CPA cannot be computed and will show as N/A.

7) How accurate are the projections?

They are directional estimates. Real outcomes depend on auction dynamics, creative quality, targeting, landing page performance, and measurement choices.

8) How should I pick CTR and conversion rate?

Start with your historical averages, then create scenarios: conservative, expected, and aggressive. Small changes in conversion rate often move profitability more than small CPC changes.
