Business Calculators Comparison
All 45 Business calculators in one comparison table, with the formula and a worked example for each.
What you can work out with these calculators
These calculators cover the operating numbers behind a small business: margin and markup, break-even volume, customer acquisition cost, lifetime value and cash runway. Each one separates the inputs you control from the assumptions you cannot, so a result can be challenged rather than just accepted.
- Convert between cost, price, margin and markup without mixing up the two percentages.
- Find the break-even unit volume from fixed costs, price and variable cost.
- Compare customer acquisition cost with lifetime value to judge whether growth pays for itself.
- Project cash runway from current balance, revenue and monthly burn.
