How it works

Tutorial

Running a business requires constant calculations—from margins and break-even to loan payments and growth projections. Having a comprehensive calculator suite eliminates errors and speeds decision-making across all business math needs.

You have two options: use the calculator above as your all-in-one business math tool, or follow this guide to manually calculate essential business metrics.

The Formula

Business CalculationFormula
Gross Margin((Revenue – COGS) ÷ Revenue) × 100
Break-Even UnitsFixed Costs ÷ (Price – Variable Cost)
Loan PaymentP × [r(1+r)^n] ÷ [(1+r)^n – 1]

Step-by-Step Calculation

Let’s perform common business calculations.

Step 1: Calculate Gross Margin

Determine profitability on sales:

MetricAmount
Monthly Revenue$150,000
Cost of Goods Sold$90,000
Gross Profit$60,000
Gross Margin %40%

Calculation: ($150,000 – $90,000) ÷ $150,000 × 100 = 40%

Step 2: Calculate Break-Even Point

Find minimum sales volume needed:

ComponentValue
Fixed Costs (monthly)$30,000
Selling Price per Unit$75
Variable Cost per Unit$45
Contribution Margin$30
Break-Even Units1,000 units

Calculation: $30,000 ÷ ($75 – $45) = 1,000 units

Step 3: Calculate Loan Payment

Determine monthly debt service:

Loan TermsValue
Loan Amount$100,000
Annual Interest Rate8%
Term5 years (60 months)
Monthly Rate0.667%
Monthly Payment$2,028

Final Answer: Monthly loan payment is $2,028

What This Means

These three calculations—margin, break-even, and debt service—form the foundation of business financial management. Understanding these numbers helps with pricing, capacity planning, and cash flow management.
