What each metric tells you
Read them in order, like a funnel. CPM is what 1,000 views cost: it shows how expensive the audience is. CTR shows whether the ad is interesting. CPC combines the two. Conversion rate shows whether your landing page or offer works, and CPA is the number that pays the bills.
| Metric | Formula | If it's bad, look at |
|---|---|---|
| CPM | Spend ÷ impressions × 1,000 | Audience size and competition |
| CTR | Clicks ÷ impressions | Ad creative, hook and offer |
| CPC | Spend ÷ clicks | CPM and CTR together |
| Conversion rate | Conversions ÷ clicks | Landing page speed, form, price, trust |
| CPA | Spend ÷ conversions | Everything above |

Questions about this tool
What is a good CPM in Nepal?
Facebook and Instagram CPMs for Nepali audiences are low by global standards, often well under USD 1. A low CPM isn't the goal on its own; cost per result is.
What is a good CTR?
For Facebook feed ads around 1% is common; Google search ads often get 3–8% because people are already searching.
What's the difference between CPA and CPL?
CPL is cost per lead; CPA is cost per action, which could be a lead, a purchase or a sign-up. The formula is the same.
Which currency should I use?
Use whatever your ads account shows. Nepali ad accounts usually bill in USD.
