Whole Hog Calculator
Calculate whole hog cooking time, charcoal amount, and servings from hog weight. Enter values for instant results with step-by-step formulas.
Formula
Cook Time = (Weight / 10) x (250 / Temp) | Charcoal = Weight x Method Factor | Servings = Weight x 0.40 / 0.5
Cook time is approximately 1 hour per 10 pounds at 250F, inversely adjusted for temperature. Charcoal requirement scales with hog weight and is modified by cooking method (pit uses 1.2x, rotisserie 0.8x, smoker 1.0x). Yield is approximately 40% of live weight, with servings based on half-pound portions.
Worked Examples
Example 1: Backyard Party for 80 Guests
Problem: You are hosting a party for 80 people and plan to pit-roast a whole hog at 250F. What size hog do you need, and how long will it take?
Solution: Hog size: 80 guests x 1.25 lbs/guest = 100 lbs\nCook time: (100 / 10) x 1.0 = 10 hours at 250F\nRest time: 1.5 hours (80-150 lb range)\nTotal time: 10 + 1.5 = 11.5 hours\nCharcoal: 100 x 1.2 (pit method) = 120 lbs\nYield: 100 x 0.40 = 40 lbs cooked meat\nServings: 40 / 0.5 = 80 servings\nCost: $350 hog + $96 charcoal = $446
Result: 100 lb hog | 11.5 hours total | 120 lbs charcoal | 80 servings | ~$5.58/serving
Example 2: Large Wedding Reception for 200 Guests
Problem: You need to feed 200 guests using a rotisserie method at 275F. Calculate requirements.
Solution: Hog size: 200 guests x 1.25 = 250 lbs (or two 125-lb hogs)\nUsing one 250-lb hog:\nCook time: (250 / 10) x 1.0 x (250/275) = 22.7 hours\nRest: 2 hours\nTotal: 24.7 hours\nCharcoal: 250 x 0.8 (rotisserie) = 200 lbs\nYield: 250 x 0.40 = 100 lbs cooked meat\nServings: 100 / 0.5 = 200
Result: 250 lb hog | ~24.7 hours | 200 lbs charcoal | 200 servings | ~$5.35/serving
Frequently Asked Questions
How long does it take to cook a whole hog?
Cooking time for a whole hog varies based on weight and cooking temperature, but a reliable rule of thumb is approximately one hour per ten pounds of hog weight at 250 degrees Fahrenheit. A 100-pound hog typically takes about 10 to 12 hours, while a 200-pound hog can require 18 to 22 hours of cooking time. The key is maintaining a steady temperature throughout the process and monitoring the internal temperature of the thickest part of the shoulder and ham. Rest time of one to two hours after cooking is also essential for allowing juices to redistribute throughout the meat.
How much charcoal do I need for a whole hog cook?
As a general guideline, plan for approximately one pound of charcoal per pound of hog for a full cook in a traditional pit. For a 100-pound hog, that means roughly 100 to 120 pounds of charcoal depending on your cooking method, weather conditions, and pit design. Pit cooking tends to use more charcoal because of heat loss, while enclosed smokers and rotisserie setups are more efficient and may only require 80 percent as much. You should also plan to add fresh charcoal every 45 to 60 minutes to maintain consistent temperature, so having a chimney starter ready to go is essential.
How many people will a whole hog feed?
A whole hog yields approximately 40 percent of its live weight in cooked, edible meat. A 100-pound hog produces about 40 pounds of pulled pork, which serves roughly 80 people at half-pound portions or about 120 pulled pork sandwiches at one-third pound each. For a party or event, plan for half a pound of cooked meat per adult guest for a main course, or one-third pound per person if you have substantial side dishes. It is always better to slightly overestimate because leftover pulled pork freezes well and can be used for multiple meals afterward.
What is the best cooking method for a whole hog?
The three main methods for cooking a whole hog are pit roasting, rotisserie, and enclosed smoker, and each has distinct advantages. Pit roasting over coals is the most traditional method and produces exceptional flavor from the combination of direct and indirect heat, but it requires more skill and attention. Rotisserie cooking provides the most even results because the constant rotation bastes the hog in its own juices, but it requires specialized equipment. Enclosed smoker or cinder-block pit cooking offers the best temperature control and is more forgiving for beginners, though it may produce less crispy skin.
What internal temperature should a whole hog reach?
The target internal temperature for a properly cooked whole hog is 195 to 205 degrees Fahrenheit in the thickest parts, which are the ham and shoulder. While the USDA safe minimum for pork is 145 degrees Fahrenheit, cooking to 195 to 205 degrees is necessary to break down the collagen and connective tissue that makes the meat pullable and tender. Always check the temperature in multiple locations, as different parts of the hog cook at different rates. The loins and ribs will reach temperature first, so some pitmasters wrap these areas in foil to prevent overcooking while waiting for the shoulders and hams to finish.
How do I estimate the cost of a whole hog cook?
The total cost of a whole hog cook includes the hog itself, fuel, and seasoning supplies. A whole hog typically costs between three and five dollars per pound depending on your region and source, with farm-direct purchases generally being cheaper than butcher shops. Charcoal adds approximately one dollar per pound of hog to the total cost. Rubs, sauces, and wood chips typically add another 20 to 50 dollars depending on quantities. For a 100-pound hog, expect to spend roughly 350 to 500 dollars total on the hog, 80 to 120 dollars on charcoal, and 30 to 50 dollars on supplies, making the cost per serving remarkably affordable at around five to eight dollars.
