Price Per Performance Calculator
This tool helps you find the best value for your money by calculating the "price per performance point" for multiple items.
To use it, enter an item's price and a corresponding performance score. Add multiple items to the table to easily compare them. The item with the lowest price per point is the best value.

Understanding Price Per Performance
What is Price Per Performance?
Price per performance is a metric used to evaluate the value of a product. It quantifies how much performance you get for every dollar you spend. It's especially useful when comparing products with different prices and different performance levels, such as computer components (CPUs, GPUs), cars, or even services.
The Formula
The calculation is straightforward:
Price per Performance = Price / Performance Score
The goal is to find the item with the lowest resulting number, as this indicates you are paying less for each "unit" of performance, making it the superior value.
10 Real-World Examples
Click on an example to see how the calculation works in practice.
Example 1: High-End CPU Battle
Scenario: Choosing between two top-tier CPUs.
Item A: "Intel Core i9-14900K", Price: $550, Performance Score (Cinebench R23): 38,000
Item B: "AMD Ryzen 9 7950X", Price: $500, Performance Score (Cinebench R23): 37,500
Calculation A: $550 / 38,000 = $0.0145 per point
Calculation B: $500 / 37,500 = $0.0133 per point
Conclusion: The AMD Ryzen 9 offers better value (a lower price per point).
Example 2: Mid-Range Graphics Cards
Scenario: Finding the best value GPU for 1440p gaming.
Item A: "NVIDIA RTX 4060", Price: $300, Performance Score (Avg FPS in a game benchmark): 110
Item B: "AMD RX 7600", Price: $270, Performance Score (Avg FPS in a game benchmark): 98
Calculation A: $300 / 110 = $2.73 per FPS
Calculation B: $270 / 98 = $2.76 per FPS
Conclusion: The RTX 4060 provides slightly better value, giving you more performance (FPS) for each dollar spent.
Example 3: Electric Car Range
Scenario: Comparing electric cars based on their range.
Item A: "Tesla Model 3 LR", Price: $47,000, Performance Score (EPA Range): 333 miles
Item B: "Hyundai Ioniq 6 SE", Price: $42,500, Performance Score (EPA Range): 361 miles
Calculation A: $47,000 / 333 = $141.14 per mile of range
Calculation B: $42,500 / 361 = $117.73 per mile of range
Conclusion: The Hyundai Ioniq 6 is a significantly better value if range is your primary performance metric.
Example 4: SSD Storage Speed
Scenario: Choosing a fast 2TB NVMe SSD.
Item A: "Samsung 990 Pro 2TB", Price: $170, Performance Score (Read Speed MB/s): 7450
Item B: "Crucial P5 Plus 2TB", Price: $110, Performance Score (Read Speed MB/s): 6600
Calculation A: $170 / 7450 = $0.0228 per MB/s
Calculation B: $110 / 6600 = $0.0167 per MB/s
Conclusion: The Crucial P5 Plus, while slightly slower, offers far superior value for its speed.
Example 5: Protein Powder Cost
Scenario: Finding the most cost-effective protein tub.
Item A: "Brand X Whey 5lb", Price: $70, Performance Score (Total grams of protein): 2040g
Item B: "Brand Y Whey 4lb", Price: $60, Performance Score (Total grams of protein): 1760g
Calculation A: $70 / 2040 = $0.034 per gram
Calculation B: $60 / 1760 = $0.034 per gram
Conclusion: Both brands offer identical value in terms of cost per gram of protein.
Example 6: Laptop Comparison by Review Score
Scenario: Using an overall review score (out of 10) as the performance metric.
Item A: "Dell XPS 15", Price: $1800, Performance Score: 9.1
Item B: "Apple MacBook Air", Price: $1300, Performance Score: 8.8
Calculation A: $1800 / 9.1 = $197.80 per review point
Calculation B: $1300 / 8.8 = $147.73 per review point
Conclusion: The MacBook Air provides better overall value relative to its expert review score.
Example 7: When Expensive is Better Value
Scenario: An expensive item can sometimes be a better deal if its performance is disproportionately higher.
Item A: "Standard Power Tool", Price: $100, Performance Score (Jobs per hour): 5
Item B: "Pro Power Tool", Price: $250, Performance Score (Jobs per hour): 15
Calculation A: $100 / 5 = $20 per job/hour
Calculation B: $250 / 15 = $16.67 per job/hour
Conclusion: The Pro tool, despite being 2.5x the price, is the better value because it is 3x more productive.
Example 8: LED Light Bulb Brightness
Scenario: Comparing light bulbs by their brightness (lumens).
Item A: "Brand Name Bulb", Price: $8, Performance Score (Lumens): 800
Item B: "Generic Bulb", Price: $4, Performance Score (Lumens): 750
Calculation A: $8 / 800 = $0.0100 per lumen
Calculation B: $4 / 750 = $0.0053 per lumen
Conclusion: The generic bulb offers almost double the value (brightness per dollar).
Example 9: Air Conditioners
Scenario: Comparing AC units by cooling power (BTU).
Item A: "8,000 BTU AC", Price: $300, Performance Score: 8000
Item B: "12,000 BTU AC", Price: $450, Performance Score: 12000
Calculation A: $300 / 8000 = $0.0375 per BTU
Calculation B: $450 / 12000 = $0.0375 per BTU
Conclusion: Both air conditioners offer the exact same value in terms of cooling power per dollar.
Example 10: Digital Cameras
Scenario: Comparing cameras using a sensor quality score from a technical review site.
Item A: "Sony Alpha A7 IV", Price: $2500, Performance Score (DxOMark): 97
Item B: "Canon EOS R6 II", Price: $2300, Performance Score (DxOMark): 92
Calculation A: $2500 / 97 = $25.77 per sensor point
Calculation B: $2300 / 92 = $25.00 per sensor point
Conclusion: The Canon camera is the slightly better value based on this specific technical score.
Frequently Asked Questions (FAQs)
1. What is the main purpose of this calculator?
It's designed to make objective value comparisons. It removes emotional bias and focuses purely on the math to show which product gives you the most "bang for your buck" based on a performance metric you choose.
2. Is a higher or lower "Price per Point" better?
A lower number is always better. It signifies that you are paying less money for each unit of performance, which means it is a better value.
3. Where do I find a "Performance Score"?
This is the key to a good comparison. Use reliable, objective sources. For computer hardware, use benchmark sites (e.g., Cinebench, 3DMark, PassMark). For cars, use horsepower or EPA range. For other items, you can use lumens (light bulbs), BTUs (AC units), or even total quantity (grams of protein in a tub).
4. Why is one row highlighted in green?
The row highlighted in green represents the item with the lowest "Price per Point" in your current comparison list. It is a visual indicator of the best value found so far.
5. What's the most common mistake when using this tool?
Using inconsistent performance scores. If you compare one CPU's single-core benchmark score with another CPU's multi-core score, the results will be meaningless. You must use the exact same metric for all items being compared.
6. Can I leave the "Item Name" field blank?
Yes, the name is optional. If you leave it blank, it will show up as "N/A" (Not Applicable) in the table, but the calculation will still work correctly.
7. What do I do if I get an error?
The most common error is not providing a valid number in the "Price" or "Performance Score" fields. Both fields are required and must contain numbers greater than zero for a valid calculation.
8. What if two items have the same Price per Point?
If two items have an identical value, the tool will highlight the one that was added to the list first. You can consider them to be of equal value, and your decision could then be based on other factors like brand preference or warranty.
9. Does this tool consider other factors like warranty, quality, or features?
No. This is a purely quantitative tool. It only calculates the mathematical relationship between price and a single performance metric. You should always consider other qualitative factors like build quality, customer support, and features before making a final purchasing decision.
10. Is my data saved?
No. This calculator operates entirely within your browser on the current page. If you refresh the page or close the tab, your comparison list will be cleared. To save your results, you can take a screenshot.
