EV Running Cost Calculator US
Calculate the energy used and running cost of an electric vehicle per trip and per km.
How it works
A discount reduces the original price by a percentage. The saving is the price times the discount; the sale price is what remains.
Sale price = Price × (1 − discount%)Frequently asked questions
How do I calculate a discount?
Multiply the original price by the discount percentage to get the saving, then subtract it from the original price to get the sale price.
How do I work out the original price from a sale price?
Divide the sale price by (1 minus the discount as a decimal). A price after 20% off divided by 0.8 gives the original.

More questions
How do I stack two discounts?
Apply them one after another, not by adding the percentages. A 20% then 10% discount is not 30% off — calculate the first, then take the second off the reduced price.
Does this include tax?
No. It works on the listed price. Use the tax calculator for your country to add or remove consumption tax.
