SaaS Plan Cost Calculator

About this calculator

Most B2B software is priced with a base fee plus per-seat pricing model: a flat monthly or annual charge covers the platform itself, and then each additional user or "seat" adds a fixed amount on top. Tools like project-management, CRM, and collaboration software commonly price this way, because it lets a small team pay a low entry price while letting the vendor capture more revenue as a customer's team grows.

This structure makes total cost easy to underestimate — a plan that looks affordable at five users can double or triple in cost once a team scales to twenty or fifty. This calculator takes the base price and the per-seat price and multiplies out the total bill for however many seats you need, so you can budget accurately as headcount changes or compare true total cost across competing SaaS vendors.
