Price Calculator for Cost & Profit Analysis
Understanding pricing, cost, and profit relationships is essential for business success and mathematical proficiency. This comprehensive price calculator helps you determine selling prices, profit margins, markup percentages, and cost values using proven mathematical formulas that businesses rely on daily.
Understanding Price, Cost, and Profit Calculations
Pricing strategy directly impacts business profitability and competitiveness. Whether you're a small business owner, student, or entrepreneur, mastering pricing calculations enables informed decisions about product pricing, profit targets, and market positioning.
Core Pricing Formulas
Essential Pricing Formulas:
Selling Price from Cost and Markup:
\( \text{Selling Price} = \text{Cost} + (\text{Cost} \times \frac{\text{Markup}}{100}) \)
Profit Calculation:
\( \text{Profit} = \text{Selling Price} - \text{Cost Price} \)
Profit Margin Percentage:
\( \text{Margin} = \frac{\text{Selling Price} - \text{Cost}}{\text{Selling Price}} \times 100 \)
Markup Percentage:
\( \text{Markup} = \frac{\text{Selling Price} - \text{Cost}}{\text{Cost}} \times 100 \)
Cost from Selling Price and Margin:
\( \text{Cost} = \text{Selling Price} \times (1 - \frac{\text{Margin}}{100}) \)
Selling Price from Cost and Margin:
\( \text{Selling Price} = \frac{\text{Cost}}{1 - \frac{\text{Margin}}{100}} \)
Markup vs. Margin: Key Differences
Many people confuse markup and margin, but they represent fundamentally different perspectives on profit. Markup measures profit relative to cost, while margin measures profit relative to selling price. Understanding this distinction is critical for accurate pricing and profitability analysis.
| Aspect | Markup | Margin |
|---|---|---|
| Definition | Percentage added to cost | Profit as % of selling price |
| Formula | \( \frac{\text{SP} - \text{Cost}}{\text{Cost}} \times 100 \) | \( \frac{\text{SP} - \text{Cost}}{\text{SP}} \times 100 \) |
| Base | Cost Price | Selling Price |
| Always | Higher than margin | Lower than markup |
| Example (Cost $100, Price $150) | 50% | 33.33% |
Practical Calculation Examples
Example 1: Calculate Selling Price from Cost and Markup
Given: Cost Price = $125.00, Markup = 40%
Solution:
\( \text{Selling Price} = 125 + (125 \times \frac{40}{100}) \)
\( \text{Selling Price} = 125 + 50 = \$175.00 \)
\( \text{Profit} = 175 - 125 = \$50.00 \)
\( \text{Margin} = \frac{50}{175} \times 100 = 28.57\% \)
Example 2: Calculate Cost from Selling Price and Margin
Given: Selling Price = $500.00, Margin = 60%
Solution:
\( \text{Cost} = 500 \times (1 - \frac{60}{100}) \)
\( \text{Cost} = 500 \times 0.40 = \$200.00 \)
\( \text{Profit} = 500 - 200 = \$300.00 \)
\( \text{Markup} = \frac{300}{200} \times 100 = 150\% \)
Example 3: Find Margin When You Know Cost and Selling Price
Given: Cost = $80.00, Selling Price = $120.00
Solution:
\( \text{Profit} = 120 - 80 = \$40.00 \)
\( \text{Margin} = \frac{40}{120} \times 100 = 33.33\% \)
\( \text{Markup} = \frac{40}{80} \times 100 = 50\% \)
Converting Between Markup and Margin
Since markup and margin are related but different, you can convert between them using mathematical formulas. These conversions are invaluable when comparing pricing strategies or analyzing competitor pricing.
Conversion Formulas:
Convert Markup to Margin:
\( \text{Margin} = \frac{\text{Markup}}{1 + \text{Markup}} \)
(Express markup as decimal, e.g., 50% = 0.50)
Convert Margin to Markup:
\( \text{Markup} = \frac{\text{Margin}}{1 - \text{Margin}} \)
(Express margin as decimal, e.g., 40% = 0.40)
Markup to Margin Conversion Table
| Markup % | Margin % | Markup % | Margin % |
|---|---|---|---|
| 10% | 9.09% | 60% | 37.50% |
| 20% | 16.67% | 80% | 44.44% |
| 30% | 23.08% | 100% | 50.00% |
| 40% | 28.57% | 150% | 60.00% |
| 50% | 33.33% | 200% | 66.67% |

Frequently Asked Questions
What is the difference between markup and margin?
Markup is the percentage added to the cost price to determine the selling price, calculated as \( \frac{\text{Selling Price} - \text{Cost}}{\text{Cost}} \times 100 \). Margin is the profit as a percentage of the selling price, calculated as \( \frac{\text{Selling Price} - \text{Cost}}{\text{Selling Price}} \times 100 \). A 50% markup equals a 33.33% margin because they use different bases for calculation.
How do I calculate selling price from cost and markup?
Use the formula \( \text{Selling Price} = \text{Cost} + (\text{Cost} \times \frac{\text{Markup}}{100}) \). For example, if cost is $100 and markup is 25%, then \( \text{Selling Price} = 100 + (100 \times 0.25) = \$125 \).
How do I calculate profit margin percentage?
Profit margin percentage is calculated using \( \text{Margin} = \frac{\text{Profit}}{\text{Selling Price}} \times 100 \), or equivalently \( \text{Margin} = \frac{\text{Selling Price} - \text{Cost}}{\text{Selling Price}} \times 100 \). This shows what percentage of your selling price is profit.
What is the formula to find cost if I know selling price and margin?
To find cost from selling price and margin, use \( \text{Cost} = \text{Selling Price} \times (1 - \frac{\text{Margin}}{100}) \). For example, if selling price is $200 and margin is 40%, then \( \text{Cost} = 200 \times (1 - 0.40) = \$120 \).
How can I convert markup to margin?
To convert markup to margin, use the formula \( \text{Margin} = \frac{\text{Markup}}{1 + \text{Markup}} \) where markup is expressed as a decimal. For example, a 100% markup (1.00) equals \( \frac{1.00}{1 + 1.00} = 0.50 \) or 50% margin.
Why is markup always higher than margin for the same profit?
Markup is calculated based on the smaller number (cost), while margin is calculated based on the larger number (selling price). Since the profit amount is the same but divided by different bases, markup will always yield a higher percentage than margin.
What is a good profit margin for retail business?
Typical retail profit margins vary by industry but generally range from 20% to 50%. Grocery stores often operate on 1-3% margins with high volume, while jewelry and luxury goods may have 50-70% margins. Research your specific industry for accurate benchmarks.
How do discounts affect profit margin?
Discounts reduce selling price while cost remains constant, directly decreasing profit and margin percentage. A 10% discount does not simply reduce margin by 10 percentage points—the impact on margin percentage depends on your original margin structure and requires recalculation.
