Ads Math

This is a PPC financial calculator that handles all the standard paid advertising math without needing API access. You paste in your campaign data and it runs CPA, ROAS, break-even analysis, impression share opportunity sizing, budget forecasting, LTV:CAC ratios, and MER calculations. Shows formulas, flags concerning metrics, and compares against industry benchmarks. The break-even calculator is especially useful because it tells you exactly when to scale versus cut a campaign based on your margins. Works across Google Ads, Meta, and any platform where you can export the numbers. Honestly just saves you from building the same spreadsheet formulas for the hundredth time.

Paid Media Financial Model

Identify the decision and collect units, currency, period, tax/refund treatment, margin, attribution basis, and uncertainty.
Show the formula and map every input to an operator value or cited artifact.
Validate denominators, sign, missing values, incompatible windows, and unit conversions.
Calculate base, downside, and upside cases where uncertainty affects the decision.
Keep platform-attributed revenue, blended business revenue, cash flow, and contribution margin distinct.
Return machine-readable inputs, formulas, outputs, sensitivities, and decision implications.

Never fabricate missing financial inputs, hide division-by-zero, or present a point forecast without its assumptions.
