Business Operations Calculators

Three price tools in one: add sales tax to an amount, take a discount off a list price, and mark up a cost to a sell price.

Monthly rent and full lease cost for a gym or studio space from square footage, rate per sqft, months rented and a utilities & cleaning add-on.

Units and revenue needed to break even, the contribution margin per unit, and your margin of safety at an expected sales volume.

The hourly rate a freelancer or consultant must charge — from target income, overhead, billable hours and time off — checked against a market rate.

Margin % and markup % from a cost and price — and the reverse: the price that hits a target margin on a given cost.

Months of runway from cash on hand, monthly burn and growing revenue — with a month-by-month cash balance table and the month the money runs out.
