## All calculators
- [Break-Even Calculator](https://codeasystem.com/calculators/business/break-even-calculator.md); Find how many units you must sell; and how much revenue that takes; before your business covers its fixed costs.
- [Profit Margin Calculator](https://codeasystem.com/calculators/business/profit-margin-calculator.md); Turn revenue and cost into gross profit, gross margin percentage and markup on cost; the three numbers behind every pricing conversation.
- [Markup ↔ Margin Calculator](https://codeasystem.com/calculators/business/markup-margin-calculator.md); Convert between markup on cost and gross margin on price in either direction, with the implied selling price or unit cost shown alongside.
- [MRR Calculator](https://codeasystem.com/calculators/business/mrr-calculator.md); Compute monthly recurring revenue from your subscriber base and average plan price, with the annualized ARR equivalent.
- [Churn Rate Calculator](https://codeasystem.com/calculators/business/churn-rate-calculator.md); Measure the share of customers lost over a period and see the average customer lifetime it implies.
- [Customer Lifetime Value Calculator](https://codeasystem.com/calculators/business/customer-lifetime-value-calculator.md); Estimate the gross profit an average customer generates over their entire relationship with your business.
- [CAC Calculator](https://codeasystem.com/calculators/business/cac-calculator.md); Work out the fully-loaded cost of acquiring a customer by dividing total sales and marketing spend by new customers won.
- [LTV:CAC Ratio Calculator](https://codeasystem.com/calculators/business/ltv-to-cac-ratio-calculator.md); Check whether customer lifetime value comfortably exceeds acquisition cost, benchmarked against the classic 3:1 rule of thumb.
- [Runway & Burn Rate Calculator](https://codeasystem.com/calculators/business/runway-burn-rate-calculator.md); Calculate net monthly burn from revenue versus expenses and translate your cash balance into months of runway.
- [SaaS Rule of 40 Calculator](https://codeasystem.com/calculators/business/saas-rule-of-40-calculator.md); Score your software company on the rule of 40: revenue growth percentage plus profit margin should beat 40.

Each link above points to the full Markdown reference for that calculator (inputs, formula, worked example, FAQs). The interactive HTML version lives at the same path without the `.md` suffix.
