Interactive calculators that turn each chapter into a real exercise. Plug in your business — see the math from the book applied to your numbers in seconds.
Enter your fixed costs, variable cost per unit, and sale price. Get break-even units, revenue target, margin of safety, and a live chart you can show your CPA — or your spouse.
Bring your last processor statement. FeeQuery — the same analyzer Driven Payments uses with merchants — breaks down every fee line and tells you exactly what's negotiable.
Wages, taxes, benefits, turnover, training, ramp-up. The fully-loaded hourly cost of every position — usually 1.5× to 2× the wage on the schedule.
What a customer is worth across their lifetime. What you can afford to spend to acquire them. The math behind every paid ad you've been afraid to run.
Paste your last 30 days of items. See the 20% driving 80% of revenue, the dead-weight bottom 20%, and a one-glance Pareto chart with the cut list.
How many days your money is locked between paying suppliers and collecting from customers. The single most useful number nobody on your bookkeeper's monthly report ever shows you.
The single number sophisticated operators schedule against. Plug in a shift, day, or week — see where you land on the band for your concept and exactly how much margin is on the table.
