About planning calculators

Paid media is where most ecommerce marketing budgets are spent and where the biggest efficiency mistakes happen. The headline metric — ROAS — is widely reported but routinely misunderstood. Platform ROAS captures click-attributed conversions but misses incremental impact, brand contribution, and view-through value. MER (blended marketing efficiency ratio) catches the rest. Most operators need both metrics; they answer different questions.

These 19 calculators cover the full paid media stack: efficiency math (ROAS, CAC, CPA, MER, breakeven), creative performance (hook rate, fatigue detection, format selection), pacing (daily / weekly / monthly run rate), bid strategy comparison (manual vs auto vs Advantage+ vs PMAX), and audience economics (lookalike ROI, retargeting pool sizing, audience overlap).

The benchmarks built into the calculators reflect 2026 platform realities: Meta CPM averaging $8-25 for DTC, Google Search CPC ranging $1-15+ by category, TikTok CPM 30-50% cheaper than Meta but with weaker conversion intent. ROAS targets vary by funnel stage — TOFU campaigns at 1-2× breakeven, BOFU retargeting at 3-5×+. Use the calculators to model your specific economics rather than chasing industry-average targets.

Pair these with the unit economics calculators (LTV:CAC, contribution margin, payback period) and attribution calculators (incrementality, channel mix modeling) to build a complete picture of paid media efficiency. Most underperforming accounts have at least one calculation error in their core paid math — these tools surface those errors quickly.
