- Customer LTV and CAC CalculatorWhat a customer is worth over their lifetime, what it costs to win one, the ratio between the two and how many months of margin it takes to earn the acquisition cost back.
- Debt to Equity Ratio CalculatorHow much of a business is funded by what it owes rather than by its owners: the debt-to-equity ratio, the debt ratio and equity multiplier, and whether operating profit covers the interest.
- Depreciation CalculatorDepreciation of an asset year by year by the straight-line or the written-down-value (declining balance) method, from its cost, salvage value and useful life.
