MarginBase: Margin & Pricing

MarginBase is a pricing and profit calculator for small business owners and solo operators. Enter a few numbers, get a useful answer immediately, and move on. No accounts, no subscriptions, no cloud setup, no long onboarding.

One narrow promise: help you decide what to charge, what you earn, and what volume you need. No ads, no subscriptions, no sign-in — a one-time purchase you own.

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.
