Unit Rate Calculator
Find price per unit and compare deals
Example: 12 (ounces, items, pounds, etc.)
Example: $3.99
How to Calculate Unit Rate
Identify Total Cost and Quantity
Note the total price and the number of units (items, ounces, pounds, etc.).
Divide Cost by Quantity
Unit Rate = Total Cost ÷ Number of Units
Compare (Optional)
Calculate unit rates for different options and choose the lowest.
Examples
Example 1: Groceries - 12 oz for $3.99
Unit Rate = $3.99 ÷ 12 oz
Answer: $0.3325 per ounce
Example 2: Comparing cereal boxes
Box A: 18 oz for $4.49 = $0.249 per oz
Box B: 24 oz for $5.29 = $0.220 per oz
Box B is the better deal (saves $0.029 per oz)
Example 3: Bulk buying - 50 items for $24.99
Unit Rate = $24.99 ÷ 50 items
Answer: $0.50 per item
About Unit Rates
A unit rate is a ratio that compares a quantity to one unit of another quantity. The most common unit rate is price per unit, which helps you determine the best value when shopping.
Why Unit Rates Matter
- Save Money: Find the best deals when shopping
- Fair Comparisons: Compare products of different sizes
- Budget Planning: Calculate cost per serving or use
- Bulk Buying: Determine if bulk purchases save money
Common Unit Rates
- Price per ounce: $0.25/oz
- Miles per gallon: 30 mpg
- Cost per kilowatt-hour: $0.12/kWh
- Hourly wage: $15/hour
- Price per pound: $2.99/lb
Shopping Tips
- Check unit prices on shelf tags (often shown below main price)
- Bigger isn't always cheaper - calculate to be sure
- Consider waste - buying bulk only saves if you'll use it all
- Store brands often have better unit prices
- Watch for sales - sale prices can beat bulk pricing

What is a unit rate?
A unit rate is a comparison of two measurements where one of the measurements is expressed as 1 unit. For example, $3 per pound means $3 for every 1 pound.
Why is the smaller package sometimes cheaper per unit?
Companies know people assume bulk is cheaper. Sometimes smaller sizes are on sale, or bulk packaging costs more to produce. Always calculate!
Should I always buy the lowest unit price?
Not always. Consider storage space, expiration dates, and whether you'll actually use the quantity. Food waste is expensive!
Do stores have to show unit prices?
In many places, yes! Unit pricing laws require stores to display price per unit on shelf tags to help consumers make informed decisions.
Can I use this for other rates like speed?
Absolutely! Unit rates apply to any comparison: miles per hour, words per minute, dollars per hour, etc.
