# HowCalculate ## Posts - [What Is a Good CTR? Real Numbers for Meta, Google, YouTube and TikTok ](https://howcalculate.com/blog/what-is-a-good-ctr/): You open your ad dashboard and see a CTR of 1.2%. Is that good? Should you be worried, or happy? It depends on where the ad ran. A 1.2% click-through rate is below the typical Meta benchmark (about 2.39%), below the Google Ads figure in Triple Whale’s ecommerce data (about 1.65%), and well above the TikTok median in the same dataset (about 0.61%). That is why “what is a good CTR?” has no single answer, and why most guides on it leave you more confused than before. This guide gives you the real numbers for each platform, explains why they differ, […] - [How to Calculate CPA: Formula, Examples and Benchmarks](https://howcalculate.com/blog/how-to-calculate-cpa/): CPA, or cost per acquisition, is what you pay for each result your ads bring in. The formula is simple: total ad cost ÷ number of acquisitions. Spend $1,000 and get 25 acquisitions, and your CPA is $1,000 ÷ 25 = $40. An acquisition is just whatever result you decide to count. It could be a sale, a lead or a signup. In this guide, I’ll show you how to calculate CPA step by step, what the number is really telling you, and how to work out a CPA you can actually afford. (This is the marketing CPA, not the accounting […] - [Average CPM by Platform: Meta, TikTok, YouTube and More](https://howcalculate.com/blog/average-cpm-by-platform/): There is no single average CPM. In the latest ecommerce data, the median CPM is $15.06 on Meta, $8.08 on Amazon and $4.08 on TikTok. YouTube and LinkedIn don’t share official averages. Published roundups put YouTube at roughly $5 to $18 and LinkedIn at $20 to $60 for every 1,000 impressions. This guide shows what each platform costs, which numbers are solid and which are rough, what $1,000 gets you, and why YouTube’s CPM and RPM are not the same thing. You can try your own numbers in the CPM calculator. Average CPM by platform at a glance Platform Typical CPM […] - [What Is a Good ROAS? Benchmarks by Platform and Industry](https://howcalculate.com/blog/what-is-a-good-roas/): A good ROAS is one that clears your break-even ROAS: 1 ÷ your margin before ad spend. If you keep 40% of each sale before paying for ads, you break even at 2.5x. Above that, your ads contribute toward profit before overhead. Below it, they don’t cover the costs included in your margin. You can find yours in seconds with the ROAS calculator. Benchmarks are still useful as a sanity check. In the latest published data, median ecommerce ROAS runs from 1.51x on TikTok to 3.27x on Google Ads, with Meta at 1.88x and Amazon at 3.08x.
