My daily job requires me to issue a quotation to customer. In most cases I need to calculate how many percent I should increase the price.
Using a normal calculator or windows calculator to calculate percentage or adding a percentage is easy.
For example, I purchase a 98.00 dollar RAM and sell it 35% higher. Using a calculator, I will just press 98 then + then 35 then % then =. I got 132.2.
This is easy if it's only for 1 item. But if I need to calculate a few item, then I will start making a mistake.
A friend had thought me using Microsoft Excel formula and here's 2 type of calculation involving percentage that I will use when preparing a quotation with Microsoft Excel.
1. Calculate Percentage by deciding selling price.
Using this formula, I will need to play around with my selling price to get the percentage.
The formula is: =(Price-Cost)/Cost
2. Calculate selling Price by deciding Percentage
Using this formula, will need to decide how many percent I want to increase or maybe decrease my selling price.
The Formula is: =Cost*(1+Percentage)
