Frequently asked questions

Which calculators do I need to run a P&L review?

Margin + Break-Even + Burn Rate + Runway give you the contribution-margin and time-to-zero picture. Add CAC and LTV for unit-economics health. The Business Metrics Fundamentals guide explains how the five numbers connect.

What's the difference between CAC and SaaS CAC payback?

CAC is the dollars spent to acquire one new customer (marketing + sales / new customers). SaaS CAC payback is the number of months of gross profit that customer must generate before they pay back the CAC. Healthy SaaS payback is <12 months.

Are the payroll calculators US-only?

The federal Payroll Tax calculator is US-only (FICA, FUTA, federal withholding). The Employee Cost and Contractor vs Employee calculators expose the underlying tax-rate inputs so you can model any jurisdiction.

Do these tools handle multi-currency?

Most accept currency-agnostic inputs (you choose the currency on entry). The Currency Converter on the Daily Life hub handles live cross-rates if you need to translate between two currencies first.
