The Cat Food Break-Even Price Estimator compares package sizes on an equal weight basis. Starting with the price and weight of a reference package, it calculates the maximum price a candidate package can cost while matching the same price per kilogram.
This is useful when bag or case sizes differ enough that shelf prices are hard to compare directly. The break-even result is a neutral comparison point: a candidate price below it has a lower unit cost, while a price above it has a higher unit cost. The calculation does not account for coupons, taxes, shipping, spoilage, or differences in formulation and nutritional value.
1. Enter the reference price
Use the actual purchase price of the package you want to benchmark.
2. Enter reference weight
Use net food weight in kilograms.
3. Enter candidate weight
Enter the net weight of the alternative package.
4. Compare with shelf price
If the actual candidate price is below the break-even result, its price per kilogram is lower than the reference package.
Both package weights must represent the same type of quantity. This comparison evaluates price per weight only, not nutrient density or feeding cost per day.
The break-even price is the candidate package price that produces exactly the same cost per kilogram as the reference package.
Compare products on other attributes as well when ingredients, calorie density, package waste, or storage life differ.
Given
Calculation
$28.99 ÷ 4.5 = $6.4422 per kg. $6.4422 × 6.8 = $43.807.
Result
About $43.81.
A 6.8 kg candidate below about $43.81 is cheaper per kilogram than the reference package; above that price it is more expensive per kilogram.
Not necessarily. Formula, calorie density, your cat’s tolerance, package freshness, and waste can matter more than price per kilogram alone.
Yes, if you want to compare what you will actually pay. Enter the after-discount reference price before taxes or shipping unless you also plan to include those costs consistently.
Only if weight is a meaningful basis for your decision. Wet and dry foods can differ greatly in moisture and energy density, so cost per day may be more informative.
The two packages have the same price per kilogram based on the entered values.
Break-even price compares package unit cost at one point in time. A yearly cost estimator incorporates ongoing consumption to estimate spending over a longer period.
