Founders with Successful Saas Apps - How much does your hosting cost?

At Less Annoying CRM, our AWS bill is about $5000/month for ~18k users (so $0.27/user/month). This isn't just for the direct hosting, but also things like keeping extensive backups, hosting smaller testing servers, etc. We also have some other infrastructure costs such as ~$500/month for Mailgun.

I do think that what you'll find is that the per user cost will be higher when you have fewer users. For example, even if you only have one user, you still probably can't get away with the cheapest servers. You need a minimum level of power, but most of it is going unused. So the bigger you get, the more you can smooth things out and actually utilize the resources you're paying for.

Also, reserved instances (if you use AWS) can save a lot of money, but those are harder to plan for when you're small because your future growth is uncertain. As you get bigger, you'll either (a) have a better sense of what resources you'll need in the future or (b) stop scaling by making the servers bigger and instead scale by adding more servers, which works really well with reserved instances.

For the hosting of our application, not including any costs of the emails themselves, we're up at about $5k per month.

Worth bearing in mind we're an email marketing provider (EmailOctopus), so quite resource intensive in sending, storing and processing all the event data.
