Find how many units you must sell; and how much revenue that takes; before your business covers its fixed costs.

Turn revenue and cost into gross profit, gross margin percentage and markup on cost; the three numbers behind every pricing conversation.

Convert between markup on cost and gross margin on price in either direction, with the implied selling price or unit cost shown alongside.

Compute monthly recurring revenue from your subscriber base and average plan price, with the annualized ARR equivalent.

Measure the share of customers lost over a period and see the average customer lifetime it implies.

Estimate the gross profit an average customer generates over their entire relationship with your business.

Work out the fully-loaded cost of acquiring a customer by dividing total sales and marketing spend by new customers won.

Check whether customer lifetime value comfortably exceeds acquisition cost, benchmarked against the classic 3:1 rule of thumb.

Calculate net monthly burn from revenue versus expenses and translate your cash balance into months of runway.

Score your software company on the rule of 40: revenue growth percentage plus profit margin should beat 40.
