It seems that every month I receive a ton of emails from all of you asking me how to figure out how I figure out the percentage I save. (I still have to update my personal saving/spending figures for this month – the figures should be pretty interesting since we had to make a lot of purchases without coupons eek!)
Below is how I figure out the percentage saved each month:
ex. Spent $4.50 at Publix, Saved $10.00
Amount Spent (including tax) + Amount Saved = Total Value of purchase
$4.50 + $10.00 = $14.50 ($14.50 is the total value of the items I purchased)
Amount Spent/Total Value = a decimal (we’ll call the decimal “A”)
$4.50 divided by $14.50 = 0.31
Multiply A x 100 = % Spent of total items purchased
0.31 multiplied by 100 = 31
100 – % Spent = % Saved of total items purchased
100 – 31 = 69% saved
**let me know if any of you have any questions! 
Thanks for coming to Addicted to Saving! Here’s a little bit about me so you can know who’s behind all these posts!
My name is Liza and I began my money-saving journey in the Spring of 2009 as a way to stretch a limited household income. I had lost my job and my hubby was self-employed. I launched Addicted to Saving in November of 2009 and it has grown by leaps and bounds. Since then, my hubby and I have struggled with the ups and downs of two failed adoptions and are now LOVING being parents to our little man Asher who we brought home from Ethiopia in August of 2013. I feel incredibly blessed to be able to help you save money. My goal is that you will have FUN and become empowered to save more and more money each week..
You’re calculating pct spent and then subtracting that from 100. Cut out the extra step and just divide amt saved by the total. 10/14.50 = .69
do you include tax in the amount spent?
I just saw that in the post after I asked… sorry!
