How to use these calculators well
Start with realistic numbers, then test a high and low scenario. For API costs, compare expected usage against a heavier month. For freelance rates, lower the billable hours if you spend time on sales, admin, and support. The goal is a clearer planning range, not a fixed financial promise.
