Pet Food Cost Calculator
Estimate your pet food costs per day, month, and year based on bag size, price, and feeding amount.
Overview
This pet food cost calculator helps you estimate how much you spend feeding your pet based on the food price, pack size, daily portion, number of pets, and any extra allowance for waste. It can be useful when budgeting or comparing different food options.
How it works
The calculator converts the pack weight into grams, works out the cost per gram, and multiplies that by the total amount fed each day. It then adds any waste allowance and scales the result into monthly and yearly estimates. It also estimates how long one bag will last by dividing the total grams in the bag by the adjusted daily feeding amount.

If a 12 kg bag costs 45 and your dog eats 300 g per day with 5% waste, the food costs about 1.18 per day, 35.44 per month, and 431.25 per year. One bag lasts about 38.1 days.
Frequently asked questions
What does this pet food cost calculator estimate?
It estimates your pet food cost per day, month, and year, along with how long one bag or pack should last.
Should I enter the amount fed per pet or for all pets combined?
Enter the daily amount for one pet, then use the number of pets field to multiply the total automatically.
Why is there a waste allowance option?
Waste allowance helps account for spills, leftovers, inaccurate scoops, or food that is discarded rather than eaten.
Can I use this for wet food or raw food?
Yes. As long as you know the total price, total weight, and average daily feeding amount, the calculator can still give a useful estimate.
