Pricing calculations directly impact profitability. A 1% improvement in gross margin on 1M revenue equals 10,000 in additional profit. Regular monitoring of these metrics is a hallmark of high-performing businesses.

How to Use This Calculator

Enter your Change in Total Revenue (ΔTR) (e.g. 4000 in ) and Change in Quantity Sold (ΔQ) (e.g. 100 in units). Results update instantly as you type — no submit button or page reload required. Adjust any value to compare scenarios side by side.

The Formula

Marginal Revenue (MR) = Change in Total Revenue (ΔTR) ÷ Change in Quantity Sold (ΔQ)

Worked Example

Increasing sales from 500 units to 600 units increases total revenue from 20,000 to 24,

000.

• Marginal Revenue = 4,000 ÷ 100 = 40.00 per additional unit sold.

Understanding Your Result

Gross margin and markup measure the same relationship from opposite directions. A 50% markup (add 50% to cost) equals a 33% gross margin (33% of revenue is profit). Gross margins above 50% are typical for software and professional services; below 20% is common in retail and manufacturing. Contribution margin (revenue minus variable costs) is more useful for short-term pricing decisions than gross margin, which includes all product costs.
