Great questions, @Casper - thanks!
- One of the main limitations of the calculator is that it can only give you comparisons of costs and revenue when all other behaviours remain the same - in other words, if your Actor becomes a lot more popular because people can run it for the results they need rather than having to rent it, you might have tons of very low-revenue customers which add up to a lot more. It's just hard to predict this so we don't try. However, most devs have found that they're seeing fairly consistent, if not significantly improved revenue by migrating.
- not sure what you mean about losing money on higher tiers, these are usually more profitable for you. "Losing money" could mean a lot of things and I don't want to speculate in this context - feel free to DM me if you'd prefer to discuss privately.
- Apify deducts 20%.
- We don't charge you for negative revenue on your Actors but we will get in touch with you about consistently negative revenue as it signals to us that you need help somewhere.
Hopefully some of these responses answered questions you have and others moved you closer to an answer. My inbox is open if you want to continue the conversation with more specific details.
