Calculator questions

What is included in this estimate?

Is this the final cost?

We include a free template with all of the included features of the system. You can build your own industry-specific vertical from this template. We have a template marketplace, but it is optional to use. There are paid upgrades to optional features (such as document signing); these optional features are purely optional. If you build a heavy file-upload platform, such as a system that shares videos to be edited or a file-upload platform, you will need to connect your own AWS S3 buckets to the system for those files to go into.

How does the AI Support split work?

The AI Support slider starts at $5 per paid seat per month. AI Support add-on revenue is modeled separately from the base SaaS 10% share: 75% remains with the builder and 25% goes to BuildWithHQ.

Why does the system fee change with my seat price?

A low-priced SaaS should not be overwhelmed by a fixed per-seat platform cost. The calculator uses 3% of the monthly seat price per paid seat, with no per-seat dollar cap.

Is builder retention the same as profit?

No. It is the amount left after the BuildWithHQ fees modeled here. Your own payment processing, taxes, refunds, sales, support, payroll, third-party usage, and other business expenses still matter.
