FIVE FAST CALCULATORS
- Selling Price: turn cost plus a margin or markup into the price to charge.
- Margin & Markup: enter cost and selling price, see margin % and markup % together.
- Break-Even: enter fixed costs, price per unit and variable cost per unit, see the units and revenue you need to cover costs.
- Fee-Adjusted Price: enter your desired net and the platform fees, see the gross price that keeps exactly the net you want after fees.
- Monthly Cash Check: enter current cash, expected inflow and expected outflow, see your projected end-of-month balance.

MarginBase is a compact paid utility with a stable feature core and deliberately limited ambition. It is not a finance platform, not accounting software, not a collaboration tool, not a subscription service, and not an all-in-one business app. It does not do bookkeeping, invoicing, tax, inventory, forecasting, or reporting. It does one job well: quick pricing and profit math for small business.
