Frequently asked questions
Do these tools send my captions anywhere?
No. Every calculator here runs entirely in your browser, so a draft caption, an unreleased campaign, or a client's numbers never leave your device.
What's a good engagement rate to aim for?
Most accounts sit around 1–3%, and clearing 3% is genuinely strong on Instagram. Smaller, engaged accounts often beat that easily, while huge accounts tend to run lower simply because of their size.
Can I trust the YouTube earnings estimate?
Treat it as a range, not a promise. CPM swings a lot by niche and country, and the number here covers ad revenue only — sponsorships and memberships usually add far more on top.
