![]() The purpose of this is to have a quick, and visual, representation of how daily measurements compare to several ideal percentage reductions, allowing me to adjust the environmental parameters in the project. Example: 3956 SN, take 18% of that (712.08), then divide that amount by 12 days (59.34), each day subtracting another 59.34 while generating a line. What I need to figure out is how to take a starting number (call it SN, which begins all the columns I need to auto populate) then take a percentage of that, divide that amount by the number of days in the date range, and subtract sequentially down that column. Column A is a date range (fine), Column B is the days within Column A as just numbered 1->whatever (fine), Column C is data I enter with daily measurements (fine) but the starting number is what controls what I need in Column D and subsequent columns with varying percentage reduction. I have a chart I need to frequently generate, and am stumped with how to auto populate a certain column. Hello! Thank you for this wonderful resource. So how much exactly should you expect to receive back? How much is 20% of $450? Here's how you should count: Let's imagine you've spent $450 shopping abroad and you'd like to have the taxes returned – 20%. Find amount when having total and percentage Now that you've learned how to operate percentages, I hope getting total and the amount will be a child's play. =(B3-$B$2)/$B$2 Amount and total by percentage in Google spreadsheets For that, make the reference to this cell absolute instead of relative so it doesn't change after copying the formula to other cells: If you take the same sales list and decide to calculate percentage change based on January only, you will have to always refer to the same cell – B2. Here I also coloured percentage decrease with red. To make sure my formula works correctly, I should start entering it from the second row of my table – C3:Ĭopy the formula over all rows with data, apply the percent format, decide on the number of decimals, and voila: This time, I'm tracking total sales (column B) over each month (column A). I also used conditional formatting to highlight cells with percent increase with red and percent decrease with green: Don't forget to apply the percent format and adjust the number of decimal places. What part of the total is composed of all deliveries of that fruit? The SUMIF function will help answer that: Now, suppose a fruit appears more than once in your table. One item takes a few rows – all rows are part of the total I also formatted the results as percent and left 2 decimals to display: Thus, each new record will be calculated based on the sum in $B$8: This type of reference (absolute, with a dollar sign) doesn't change when you copy the formula to other cells. To find the percentage of the total for each fruit, use the same basic formula as before but with a slight difference – an absolute reference to the cell with the total sum. Their total resides at the very end of the data: B8. I believe this is the most common case: you have a table with values in column B. Let's see what else Google Sheets offers. Though the previous shows the same, it works great for that example but may not be enough for other data set. Here are a few more examples of calculating percentage of a total. ![]() Percentage of a total in a Google spreadsheet I removed all decimal places making the formula show the result as a rounded percent. Here's how the result looks on real data: You can decrease and increase decimal places if necessary using the options from the Google toolbar: If you have any suggestions or need any other help at all just let us know via the contact form in the menus.Tip. In the menu above you will find links to some other standard percentage queries with their own calculators and explanations. It is quite easy to work out these percentages as you will see, remembering a couple of basic principles is all you need to know to be able to find the answers whenever you need. Under each calculator there is a section to explain how to work these amounts out. The two percentage calculators below allow you to find what a set percentage of an amount is and also to work out what percentage an amount is from a total. This site gives everyone access to a free online calculator where you can change percentages and amounts and see the formula and workings behind the results that are shown. There are a lot of common percentage questions and problems people seem to encounter and we felt that we could make a good resource to give some assistance. ![]() Welcome to our site!
