Quick ROI for a board conversation, campaign math for a channel review, or customer economics for a growth-strategy discussion — three calculators, general-purpose, not tied to any one platform.
The simplest honest question: did this spend make money, and how much.
Investment vs. return, plain and simple
ROI% = (Revenue − Investment) ÷ Investment × 100. A useful rule of thumb: above 5:1 return is considered strong for most channels, though "good" varies hugely by industry and margin.
Instant funnel math — works for Google, Meta, LinkedIn, or any paid channel, not just one platform.
CTR, CPC, CVR, CPA in one screen
CTR = Clicks÷Impressions. CPC = Spend÷Clicks. CVR = Conversions÷Clicks. CPA = Spend÷Conversions.
Whether the business model actually works long-term — not just whether one campaign was profitable.
Customer acquisition cost vs. lifetime value
CAC = Spend÷New Customers. LTV = AOV × Frequency × Lifespan. A 3:1 LTV:CAC ratio is a commonly-cited healthy benchmark — below 1:1 means losing money on every customer.
| Metric | Weak | Healthy | Strong |
|---|---|---|---|
| Marketing ROI | < 2:1 | 3:1 – 5:1 | > 5:1 |
| LTV : CAC | < 1:1 | 3:1 | > 5:1 |
| Email CTR | < 1% | 2–3% | > 4% |
| Paid Search CVR | < 2% | 3–5% | > 6% |
These are directional, industry-general benchmarks — actual "good" varies a lot by category, margin, and channel. Use them as a sense-check, not a hard target.
