Wet & Dry Cat Food Calculator

Calculate wet and dry cat food portions, compare feeding costs, and plan purchases using your food labels and daily calorie target.

Build your feeding plan

FROM LABEL TO BOWL

Build one day. Budget the rest.

Enter a daily calorie target you already use. Need a starting estimate? Open the cat calorie calculator in a new tab. This worksheet divides that target between foods; it does not set your cat’s calorie needs.

01 Set the daily calorie budget
kcal/day
Include all food and treats in this total.
kcal/day
These calories are subtracted before splitting the foods.
02 Choose how to mix
%
All dry50% wet / 50% dryAll wet
50/50 means equal calories from the foods, not equal grams or bowl volume. This is a comparison setting, not a recommended ratio.
03 Copy the two food labels

Only a food used in your plan needs a label. Choose the calorie unit exactly as it appears on the package.

Wet food

Use the weight of one container, not the full multipack.

Dry food

Find “Calorie Content”

Copy kcal/kg, kcal/100 g or kcal/cup. Protein percentages and “cups per day” are different numbers.

04 Add prices & budget days Optional prices

Leave prices blank for portions only. Enter both active foods’ prices for the full budget. Use one currency throughout.

days

A / Wet pack

Use 1 for a single can; 12 for a 12-pack.

B / Dry bag

Meal split & more than one cat
Optional arithmetic split; foods can be served separately.
Multiplies shopping totals only. Calculate each cat separately if needs differ.

THE SAME CALORIE BUDGET

What changes when you change the mix?

Compare portions and food consumed over your budget period. Ratios are calorie shares, not nutrition rankings.

Your 25%, 50% and 75% wet-food comparisons appear after you build a plan.

“I FEED ONE CAN. HOW MUCH DRY FOOD?”

Subtract the wet calories first.

Suppose a cat’s existing target is 240 kcal/day, including 20 kcal of treats. That leaves 220 kcal for complete food. If one can supplies 100 kcal, the dry food must supply the remaining 120 kcal.

One can + 30 g dry

At 4,000 kcal/kg, dry food supplies 4 kcal per gram. Divide 120 by 4 to get 30 g of dry food, alongside the one can. Use “Start with daily cans / pouches” above to do this with your labels.

This is a worked arithmetic example, not a calorie recommendation. A different can or kibble changes the answer.

BEFORE YOU MEASURE A MEAL

Where are the calories on cat food labels?

Look for “Calorie Content,” “Metabolizable Energy” or “ME.” Copy the number and its unit together.

Wet food: check one container

“100 kcal per can” is the energy in one can. “100 kcal per 100 g” is an energy density. They only mean the same thing if that can contains exactly 100 g. Enter the net weight of a single can, pouch or tray so the calculator can also show grams.

Illustrative wet label

Net weight85 g per can
Calorie content100 kcal/can

Enter 100, choose “One can / pouch / tray,” and enter 85 g. This is a fictional label example.

Dry food: kg is not a serving

“4,000 kcal/kg” means 4 kcal per gram. It does not mean a cat needs a kilogram. A food labeled 400 kcal/100 g has the same energy density. Use whichever unit your own packaging provides.

Illustrative dry label

Calorie content4,000 kcal/kg
Same density400 kcal/100 g

If you only have kcal/cup, select cups. Grams per cup vary between foods; do not assume a universal cup weight.

FOOD COST ≠ TODAY’S RECEIPT

How much will mixed feeding cost per month?

The calculator shows both the value of food used and what you would pay to buy enough whole packs.

Food consumed during the period

Using the fictional labels above, a 50% wet / 50% dry calorie split uses 1.1 cans and 27.5 g of dry food each day. If a 12-pack costs $18 and a 2 kg dry bag costs $20, the food used costs about $1.93/day, or $57.75 over 30 days for one cat.

Amounts are calculated at full precision before money is rounded. Multiplying the displayed rounded daily price can therefore differ by a few cents.

Whole packs you need to buy

The same 30-day plan uses 33 cans and 825 g of kibble. Starting with no food in stock, you would buy three 12-packs and one 2 kg bag: $74 at checkout. Three cans and 1,175 g of dry food remain for later.

The model assumes usable leftovers carry forward. Food discarded, delivery charges, tax and treat purchases are not included. Choose your actual period; “30 days” is a budget window, not every calendar month.

OPEN CALCULATION METHOD

How does the mixed feeding calculator work?

All portions come from your calorie target and food labels. No average brand values, breed multipliers or price database are substituted.

Convert calories into food

Food budget = total target − treat calories
Wet kcal = food budget × wet percentage ÷ 100
Wet units = wet kcal ÷ kcal per unit
Dry kcal = food budget − wet kcal
Dry grams = dry kcal ÷ kcal per gram

For fixed wet units, wet calories equal units × kcal per unit. Dry food fills the remainder. If the chosen wet amount already exceeds the food budget, the calculator asks you to reduce it instead of producing a negative dry portion.

When using cups, dry cups = dry kcal ÷ kcal per cup. Grams and bag costs need that food’s grams per cup. The calculator will still give cup portions when that conversion is unknown.

Convert portions into purchases

Wet cost/day = daily units × pack price ÷ units per pack
Dry cost/day = daily grams × bag price ÷ bag grams
Food used cost = combined daily cost × days × cats
Packs to buy = round required food ÷ pack size UP to the next whole pack

The “cats” setting assumes each cat follows the exact same individual plan. It scales household shopping totals and package duration; displayed daily portions remain per cat. Use a separate worksheet when cats’ needs or foods differ.

Weight conversion: 1 oz = 28.349523125 g; 1 lb = 453.59237 g. Costs use full precision; displayed grams, units and money are rounded. Bag duration describes quantity used, not freshness or safe storage time.

What this worksheet can—and cannot—tell you

Use foods appropriate for your cat’s life stage and nutritional needs. In the US, the nutritional adequacy statement explains whether a food is “complete and balanced”; treats, toppers and complementary products may not provide a complete diet. [1] Matching calories alone does not verify nutrient balance or make a prescription diet interchangeable.

WSAVA advises treats supply no more than 10% of a cat’s daily calories. The tool flags a higher allowance, but 10% is a ceiling, not a treat target or a guarantee of nutritional suitability. [2] Use a veterinary plan for growth, pregnancy, weight loss or health conditions, and discuss changes to therapeutic diets with the treating team.

Inputs remain in the current page tab; the tool does not store a feeding profile. Site-wide analytics follow our privacy policy.

COMMON MIXED-FEEDING QUESTIONS

Wet, dry and the questions between.

How much wet and dry food should I feed my cat?
Start with an appropriate daily calorie target, subtract treats, then divide the remaining calories between the foods. Divide each food’s calorie allowance by its label’s kcal per unit or per gram. There is no universal number of cans or grams that fits all cats and products. This calculator performs the conversion; it does not prescribe your cat’s calorie target.
If I feed one can of wet food, how much dry food should I add?
Select “Start with daily cans / pouches” and enter 1. The calculator subtracts that can’s calories from the food budget and converts what remains into dry food. In the worked example above, 240 total kcal minus 20 treat kcal minus a 100-kcal can leaves 120 kcal: 30 g of a 4,000-kcal/kg dry food.
Is a 50/50 wet and dry mix equal weights?
No. Here, 50/50 means each food supplies half of the food calories after treats. Wet and dry foods can have very different energy densities, so equal calories usually require different gram amounts. The percentage is a planning choice, not a claim that 50/50 is best for your cat.
Can I mix different brands of wet and dry cat food?
The calculator accepts any labels and does not require matching brands. It cannot determine whether two products are nutritionally suitable together. Check life-stage suitability and nutritional adequacy, introduce changes with your veterinary team’s guidance, and seek advice before mixing a therapeutic diet with another food. See our mixed feeding guide for more context.
Why can I see cups but not grams or dry-food cost?
Kcal/cup tells us how much energy is in a label-defined cup, but not how many grams that cup weighs. Enter the grams per cup for this specific food or choose its kcal/kg figure instead. A generic grams-per-cup assumption would distort grams, bag duration and cost.
Why is the shopping total higher than the food cost?
Food cost counts only the portions consumed during your budget period. The shopping total starts with no stock and rounds up to whole packs and bags. Food remaining at the end still has value. The result assumes it is stored and used according to the manufacturer’s instructions.
Can I use this for two or more cats?
Yes, if each cat uses the same calorie target, labels and daily portions: expand “Meal split & more than one cat” and change the cat count. Shopping totals scale up, but the daily portions stay per cat. Cats with different requirements need separate plans.
Do wet and dry food have to be mixed in the same bowl?
No. Mixed feeding can mean wet meals and a separately measured dry portion. The worksheet totals calories over a day; its optional equal-meal division does not require feeding both formats together. Follow product instructions for serving and storing food, including opened containers and leftovers. [3]
