At the store
See what a pet-food bag costs per day
A day is that price divided by how long the bag lasts.
- Calculated from what you enter
- About 2 minutes
- Easy
The short version
- For someone who already has the numbers in hand.
- Divide a bag price by the days you type.
- It is not a decision about what you should buy, sign, or qualify for.
The moment
You type the bag price and how many days you expect the bag to last. The page divides.
After this, you can see what a pet-food bag costs per day.
Your guess first
These numbers are an illustration, not a store price. Bag price 24.00; Days 30.
The turn
The first illustration comes out to $0.80. The total split by the count, to the nearest cent. A second illustration comes out to $0.90. The total split by the count, to the nearest cent.
Why the number hides
The shelf shows the bag. The day is a number you supply from how fast the food is used.
Now run your own numbers
Do this next
- Type the total price.
- Type the count.
- Read the cost of one.
- Round-off is to the nearest cent.
- Use your own count, not a guess from the shelf.
Who this will not work for
- A price this page did not ask you to type.
- Tax, unless you folded it into a number.
- Advice about what you should buy.
A pitfall
If the bag runs out sooner, the daily cost is higher than this result.
How this was calculated
Cost per day equals the bag price divided by the days, to the nearest cent.
This is arithmetic on the numbers you type. It doesn't check store prices.
