Free SaaS Spend Calculator
Add every software subscription to calculate monthly and annual spend, category mix, cost per employee and estimated unused-seat spend. Free, no signup.
Quick answer
A SaaS spend calculator estimates the total cost of a software stack by combining seat-based subscriptions, flat monthly plans, annual contracts, usage charges, add-ons, and overages. An unused-seat scenario can then estimate how much seat-based spend deserves review before renewal.
Formula
Monthly SaaS spend = seat-based monthly cost + flat monthly subscriptions + annual contracts ÷ 12 + monthly usage and add-ons
