Formula & Mathematical Methodology: Full-Funnel Performance Marketing Identities

CPM = Spend × 1000Impressions,   CPC = SpendClicks,   ROAS = RevenueSpend,   ROASbreak-even = 11 − COGS%
CPM = (Spend / Impr) × 1000; CTR = Clicks / Impr; CPC = Spend / Clicks; CPA = Spend / Conv; ROAS = Revenue / Spend; Break-Even ROAS = 1 / (1 − COGS%)
  • ROAS: Gross attributed revenue divided by ad spend
  • Break-Even ROAS: Minimum ROAS required so gross margin covers ad spend

Rounding: Currency metrics round to 2 decimal places; ratios round to 2 decimal places.

Worked Example: $5,000 Spend, 250,000 Impressions, 4,500 Clicks, 180 Orders at $95 AOV (40% COGS)

Evaluate a paid social/search campaign spending $5,000.

  1. CPM = ($5,000 ÷ 250,000) × 1,000 = $20.00; CTR = 1.80%; CPC = $1.11.
  2. Conversion Rate = 180 ÷ 4,500 = 4.00%; CPA = $5,000 ÷ 180 = $27.78.
  3. Gross Revenue = 180 × $95 = $17,100 → ROAS = 3.42× (342%).
  4. Gross Profit before ads = $17,100 × 0.60 = $10,260; Net Profit after ads = $10,260 − $5,000 = $5,260.
Result: 3.42× ROAS, $27.78 CPA, $5,260 net profit, and 1.67× break-even ROAS.

Frequently Asked Questions

Why can a 2.5× ROAS campaign still lose money?

Because ROAS measures top-line revenue, not profit. If your COGS is 65% (35% gross margin), your break-even ROAS is 1 ÷ 0.35 = 2.86×, meaning any ROAS below 2.86× loses money on the first order.

Marketing ROAS, CPC, CPM, CPA & CTR Calculator: inputs, method, and how to read the result

Analyze your full paid ad funnel, CPM, CTR, CPC, CVR, CPA, ROAS, break-even ROAS, and net profit after COGS.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Display Currency: Amounts are treated in the selected currency; no foreign-exchange conversion is applied.
  • Total Campaign Ad Spend: Total media spend for the campaign period.
  • Total Ad Impressions: Number of times ads were served.
  • Total Link Clicks: Total clicks generated by the campaign.

What the calculation includes

With the default values shown, Return on Ad Spend (ROAS) is 3.42× (342%). The calculation follows Full-Funnel Performance Marketing Identities; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Total Campaign Ad Spend from 5,000 USD ($) to 5,500 USD ($) changes Return on Ad Spend (ROAS) from 3.42× (342%) to 3.11× (311%). This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses first-order attributed revenue (AOV) to calculate immediate campaign payback.
  • Does not include repeat customer purchases (LTV) beyond the first order.

Scope: Global Check the assumptions and limitations against your situation before relying on the estimate.
