Free M&A calculators for buyers, sellers and roll-up operators

Six calculators that answer the questions buyers, sellers and roll-up operators ask first: what the business really earns, what it is worth, what the loan costs, what the seller note and earn-out pay, and whether a group of businesses can carry its debt. Each one runs in your browser; nothing you type is sent anywhere.
