The Business Calc

Free Pricing & Profit Calculators for Small Business

What should you charge, what is each sale really worth, and how much do you have to sell? Pick the question you're trying to answer — every tool shows the formula behind its result.

  1. Start here

    How many units must I sell to stop losing money?

    Three numbers you already know — fixed costs, price, cost per unit — and you get the volume where the business turns the corner.

  2. What gets me to a profit goal?

    Finds the units and revenue needed to reach a specific profit goal.

  3. What does each sale contribute?

    Calculates contribution margin per unit in dollars and as a ratio of price.

  4. Is that a markup or a margin?

    Converts a cost and price into both markup % and margin %, and shows why they differ.

  5. What price should I charge?

    Finds the selling price that delivers a target gross margin on a known cost.

Pricing tools for specific decisions

  1. What margin does a 50% markup give?

    Reference table converting common markup percentages to margins and back.

  2. How many more sales does a discount need?

    Shows how much extra volume a discount needs to keep the same gross profit.

  3. How many customers can I lose after a price increase?

    Shows how much sales volume a price increase can lose before profit drops.

  4. What should this dish cost on the menu?

    Sets a menu price from plate cost and a target food cost percentage.

  5. What hourly rate do I need as a freelancer?

    Works out the hourly and day rate needed to hit a take-home income after tax and expenses.

How the profit calculators fit together

  1. 1 Contribution margin tells you what one sale is really worth after the cost of making it.
  2. 2 That figure drives break-even — how many sales it takes to cover your fixed costs.
  3. 3 Push past zero with target profit to find the volume that actually pays you.
  4. 4 Working on the price itself? Markup vs. margin and selling price set the number those three depend on — and the discount and price increase calculators show what changing it does.

How these work

  • Nothing leaves your browser. No figure you type is sent, stored, or tracked.
  • The math is shown. Every tool has the formula and a worked example on the page.
  • Shareable results. Copy a link to any result and it reopens with the same figures filled in.
  • Standard definitions. Ordinary cost accounting — not advice, and no substitute for an accountant.
