How to use the Cost per Use Calculator
- Purchase price
- Lifetime upkeep cost
- Expected uses
- Want to work backwards? Type a value into Cost per use and Expected uses is calculated for you.
Results update as you type, and every field accepts the units shown in its menu.
How it works
Add any upkeep costs to the price and divide by expected uses.
Tips
- Use the figures from your own bills and product labels – prices and appliance ratings vary widely.
- Look at yearly totals: small daily costs add up and make it easier to compare options.
- Round quantities up to whole packs, rolls or bulbs when you shop.
- Re-check the numbers when prices change; most results scale directly with the unit price.
Common mistakes to avoid
- Confusing watts (power) with watt-hours or kilowatt-hours (energy).
- Comparing prices without bringing them to the same unit first.
- Ignoring one-off costs such as installation, delivery or replacement parts.
