Instead of relying on averages or guesswork, plug in your own numbers and see how the key inputs, rate, term, amount, and timing, interact. Small changes to any one of them can have outsized effects over years or decades.
How to Use This Calculator

- Results appear instantly as you type; there's no "calculate" button to press.
- Change any input to compare scenarios side by side.
All math happens in your browser. Nothing you type is sent to a server, saved, or shared.
Key Inputs to Get Right
The most important numbers are usually the interest rate and the time horizon. Over years or decades, small rate differences compound into large dollar differences, so it's worth sanity-checking the rate against current market data before acting on any result.
Types of Profit Margin
- Gross Margin: (Revenue, COGS) / Revenue
- Operating Margin: (Revenue, COGS, Operating Expenses) / Revenue
- Net Margin: Net Income / Revenue
Industry Benchmarks
- Software/SaaS: 70-80% gross, 20-30% net
- Retail: 25-35% gross, 2-5% net
- Manufacturing: 25-35% gross, 5-10% net
- Restaurants: 60-70% gross, 3-5% net
Formula
Gross margin = (revenue − cost) ÷ revenue. Markup = (revenue − cost) ÷ cost. A 50% markup is only a 33% margin, the two are not interchangeable.
Worked Example
A product sells for $50 and costs $30 to produce.
- Revenue
- $50
- Cost
- $30
- Result
- 40% margin
($50 − $30) ÷ $50 × 100 = 40%.
