Business and Pricing Calculators
These calculators cover the arithmetic of running a small business: setting a price that delivers the margin you want, finding how many units cover fixed costs, spreading an asset's cost over its useful life and paying salespeople under flat, tiered or base-plus-commission plans.

Which tool do I need?
Set a price for a 40% margin
Enter the unit cost and the margin you want to get the selling price, the profit and the equivalent markup.
Find how many units I must sell to cover costs
Enter fixed costs, price and variable cost per unit to get the break-even units and revenue, and the units for a profit target.
Build a depreciation schedule for new equipment
Enter the cost, salvage value and useful life to compare straight-line, declining balance and sum-of-years schedules.
Work out a salesperson's commission under tiers
Enter the sales and each tier's rate to see the commission under marginal and whole-amount tier rules.
About Business Calculators
They are built to avoid classic mistakes. Margin and markup are different percentages of different bases, so the pricing calculator converts between them; break-even analysis separates fixed from variable costs; the depreciation calculator compares straight-line, declining balance and sum-of-years methods side by side; and the commission calculator explains whether tiers apply to each slice of sales or to the whole amount.
They support planning and pricing decisions rather than accounting or tax filings. Tax depreciation follows its own rules, such as MACRS in the United States, and commission plans are defined by the contract, so check those details with an accountant.
Guides
- Margin, Markup and Break-Even: The Arithmetic of PricingWhy a 40% markup is not a 40% margin, how contribution margin sets your break-even volume, and how sales commission and discounts eat into both.
- Depreciation Methods Compared: Straight-Line, DDB, SYD and MACRSHow each depreciation method spreads an asset's cost, when declining balance switches to straight-line, how partial years work, and where MACRS differs from book depreciation.
Frequently asked questions
Why do margin and markup give different prices?
Margin is profit as a share of the selling price; markup is profit as a share of cost. A 50% markup gives a 33.3% margin, so mixing them up underprices products.
What is a contribution margin?
The selling price minus the variable cost per unit. It is the amount each sale contributes towards fixed costs and then profit, and it drives the break-even point.
Which depreciation method fits a small business's books?
Straight-line is the simplest and most common for books. Accelerated methods suit assets that lose value quickly. Tax depreciation often follows separate rules, so ask an accountant.
How do tiered commission plans usually work?
Most pay each tier's rate only on the sales within that tier, like tax brackets. Some pay the highest reached rate on all sales, which costs much more at the boundaries.
