The basic way to calculate a discount is to multiply the original price by the decimal form of the percentage. To calculate the sale price of an item, subtract the discount from the original price. You can do this using a calculator, or you can round the price and estimate the discount in your head.
How do you calculate percentage off?
- The rate is usually given as a percent.
- To find the discount, multiply the rate by the original price.
- To find the sale price, subtract the discount from original price.
What is 30% off $50?
Bean coupon of $50 and you want to know the final or sale price if the discount is 30 percent. This means the cost of the item to you is $35. You will pay $35 for a item with original price of $50 when discounted 30%.

- To turn a number (either an integer or a decimal) into a percent, simply multiply by 100.
- To turn a percent into an integer or decimal number, simply divide by 100.
- 50% as a decimal is 0.50.
- 3.5% = 0.035.
To find the speed, distance is over time in the triangle, so speed is distance divided by time. To find distance, speed is beside time, so distance is speed multiplied by time. Distance Speed Time Formula Questions: 1) A dog runs from one side of a park to the other.
Bean coupon of $100 and you want to know the final or sale price if the discount is 20 percent. This means the cost of the item to you is $80. You will pay $80 for a item with original price of $100 when discounted 20%. In this example, if you buy an item at $100 with 20% discount, you will pay 100 - 20 = $80.
Select a blank cell, for instance, the Cell C2, type this formula =(B2-A2)/ABS(A2) (the Cell A2 indicates the original price, B2 stands the sales price, you can change them as you need) into it, and press Enter button, and then drag the fill handle to fill this formula into the range you want. See screenshot: 3.
There are two steps to calculating a 10 percent discount:
- Step 1 is to convert your percentage to a decimal, the formula for which is 10 / 100 = 0.1. So 10 percent as a decimal is 0.1.
- Step 2 is to multiply your original price by your decimal.
'marked price' is the normal price of the thing without a discount, and. 'discount' is either a dollar amount, or a percentage of the marked price.
If your calculator does not have a percent key and you want to add a percentage to a number multiply that number by 1 plus the percentage fraction. For example 25000+9% = 25000 x 1.09 = 27250. To subtract 9 percent multiply the number by 1 minus the percentage fraction. Example: 25000 - 9% = 25000 x 0.91 = 22750.
Multiply the cost of an item or service by the sales tax in order to find out the total cost.
- Make sure you put the sales tax into decimal form. You do this by taking the percentage and sliding the decimal point two places to the left:
- Example: $60 (item cost) x .075 (sales tax) = $4.5 total sales tax.
To calculate the percentage increase:
- First: work out the difference (increase) between the two numbers you are comparing.
- Increase = New Number - Original Number.
- Then: divide the increase by the original number and multiply the answer by 100.
- % increase = Increase ÷ Original Number × 100.
Tip: You can also multiply the column to subtract a percentage. To subtract 15%, add a negative sign in front of the percentage, and subtract the percentage from 1, using the formula =1-n%, in which n is the percentage. To subtract 15%, use =1-15% as the formula.
We know that we need a formula that will calculate 15% of $78.77. Whenever you see the phrase "of something" in a percentage problem, it's a hint that you need to multiply. So we'll need to multiply $78.77 by 15% to find the discount. When you're using percentages within formulas, you'll want to write them as decimals.
If you want to know what percent A is of B, you simple divide A by B, then take that number and move the decimal place two spaces to the right. That's your percentage! To use the calculator, enter two numbers to calculate the percentage the first is of the second by clicking Calculate Percentage.
Then add that to the original unit cost to arrive at the sales price. The markup equation or markup formula is given below in several different formats. For example, if a product costs $100, then the selling price with a 25% markup would be $125.
To calculate the discount factor for a cash flow one year from now, divide 1 by the interest rate plus 1. For example, if the interest rate is 5 percent, the discount factor is 1 divided by 1.05, or 95 percent.
The discount rate is the rate of return used in a discounted cash flow analysis to determine the present value of future cash flows. This rate of return (r) in the above formula is the discount rate.

Just follow these few simple steps:
- get the original price (for example $90 )
- get the the discount percentage (for example 20% )
- calculate the savings: 20% of $90 = $18.
- subtract the savings from the original price to get the sale price: $90 - $18 = $72.
- you're all set!
15% is 10% + 5% (or 0.15 = 0.1 + 0.05, dividing each percent by 100). Thinking about it this way is useful for two reasons. First, it's easy to multiply any number by 0.1; just move the decimal point left one digit. For example, 75.00 x 0.1 = 7.50, or 346.43 x 0.1 = 34.64 (close enough).
To get around this, you can calculate your numbers as percentages first. For example, if you type the formula =10/100 in cell A2, Excel will display the result as 0.1. If you then format that decimal as a percentage, the number will be displayed as 10%, as you 'd expect.
To calculate the percentage of the whole number, you need to first turn the percentage into a decimal as already described. Then simply multiply. For example, completing the problem of finding 15% of 100, rewrite the 15% as 0.15. Then just multiply 0.15 x 100, to get the solution of 15.
