Percentage Calculator for Business — Markup, Margin, and KPI Tracking
Table of Contents
Percentage calculations run through every part of business: pricing (markup vs margin), performance tracking (KPIs), financial reporting (revenue change), and forecasting (growth targets). Here's how to handle the most common business percentage calculations using the free Percentage Calculator.
Profit Margin vs Markup — The Most Confused Percentage
Margin and markup both express profit as a percentage, but they use different denominators:
- Margin = Profit ÷ Revenue × 100 (profit as a % of what you charge)
- Markup = Profit ÷ Cost × 100 (profit as a % of what you paid)
| Cost | Price | Profit | Margin | Markup |
|---|---|---|---|---|
| $40 | $60 | $20 | 33.3% | 50% |
| $25 | $50 | $25 | 50% | 100% |
| $80 | $100 | $20 | 20% | 25% |
To calculate margin with the Percentage Calculator: use "X is what % of Y?" — enter profit as X, revenue (selling price) as Y. For markup: enter profit as X, cost as Y.
Revenue and Sales KPI Percentage Calculations
Common business KPIs that use percentage calculations:
| KPI | Formula | Calculator Mode |
|---|---|---|
| Revenue growth (MoM) | (New - Old) / Old × 100 | % Change |
| Goal attainment | Actual / Goal × 100 | X is what % of Y? |
| Conversion rate | Conversions / Visitors × 100 | X is what % of Y? |
| Discount rate | Discount / Original × 100 | X is what % of Y? |
| Cost as % of revenue | Cost / Revenue × 100 | X is what % of Y? |
| Budget utilization | Spent / Budget × 100 | X is what % of Y? |
Pricing: How to Calculate Selling Price from Cost + Margin
If you know your cost and want a specific gross margin:
Selling Price = Cost / (1 - Desired Margin %)
| Cost | Target Margin | Selling Price |
|---|---|---|
| $30 | 40% | $30 / 0.60 = $50.00 |
| $50 | 25% | $50 / 0.75 = $66.67 |
| $100 | 33% | $100 / 0.67 = $149.25 |
To calculate selling price from markup: Selling Price = Cost × (1 + Markup %)
For a 50% markup on a $40 cost: $40 × 1.50 = $60.
Tracking Business Metrics With Percent Change
Use the % Change mode for any before/after comparison:
- Revenue this month vs last month
- Subscriber count today vs 90 days ago
- Average order value this quarter vs last quarter
- Customer acquisition cost this year vs last year
Enter the older value as "Old Value" and the current value as "New Value." Positive result = growth. Negative = decline.

Open Free Percentage CalculatorFrequently Asked Questions
What's the difference between margin and markup?
Margin is profit as a percentage of selling price. Markup is profit as a percentage of cost. Example: if you buy for $40 and sell for $60, your margin is 33.3% (profit/price) and your markup is 50% (profit/cost). Always clarify which one you mean in business discussions — they're not interchangeable.
How do I calculate if I've hit my sales target?
Use "X is what % of Y?" — X = actual sales, Y = target. If you sold $82K against a $100K target, you're at 82% of goal. Subtract from 100 to see you're 18% short.
How do I calculate a 30% margin on a product?
Use the formula: Selling Price = Cost / (1 - 0.30). For a $70 cost: $70 / 0.70 = $100 selling price, which gives you exactly 30% margin ($30 profit / $100 price).
