Steak is naturally one of the lowest-carb foods you can eat: a plain cooked beef steak typically contains 0 grams of carbohydrate per 100g. The carb count only changes when you add marinades, sauces, dry rubs, glazes, or flour-based coatings. For anyone tracking macros, following keto, or managing blood sugar, knowing those added carbs is the difference between a 0g meal and one that quietly pushes you over your daily target.
This calculator estimates the carbohydrate content of your finished steak dish per 100g. Enter the total cooked weight of the steak and any clinging sauce or marinade, add the carbohydrate grams contributed by your seasonings, and choose a serving size. You’ll get both the per-100g value and the total carbs in your portion.
It’s ideal for home cooks, keto dieters, low-carb meal planners, and anyone who wants a fast, practical nutrition estimate for ribeye, sirloin, tenderloin, flank, skirt, or any other beef cut.

How to Use This Tool
Start by weighing the finished steak dish after cooking — this means the cooked steak plus any sauce, marinade, or rub that actually remains on the meat. If you used a marinade, do not include the leftover liquid you poured away; that carbohydrate never made it into the meal. Next, work out the carbohydrate grams from your seasonings and coatings. Many bottled sauces list “total carbohydrate” on the label, which is exactly the number you want. If you used a dry rub with sugar, measure the rub by volume and use its label or the reference table below.
Once you have the total weight and the added carbs, enter your planned serving size. The calculator converts ounces to grams automatically, so you can use whichever unit is on your food scale.
How the Calculation Works
The calculator assumes plain cooked beef contains approximately 0 g of digestible carbohydrate per 100 g. All of the carbohydrate in the finished dish therefore comes from the additions. The formula is straightforward:
Carbs per 100 g = (total added carbs ÷ total cooked weight in grams) × 100
Once it knows the per-100g value, it scales that to your serving size:
Serving carbs = carbs per 100 g × serving weight in grams ÷ 100
This method handles any batch size. A 400 g steak with 8 g of added sugar glaze spread across the whole surface works the same way as a 300 g steak with 5 g of teriyaki marinade: the per-100g number is what changes as the ratio of sauce to meat changes.
Why Steak Is Naturally Low-Carb
Steak is the muscle tissue of cattle, and like other unprocessed meat, it contains essentially no carbohydrates. The small amount of glycogen stored in muscle is rapidly broken down after slaughter and during cooking, so the USDA lists most cuts of cooked beef at 0 g of carbohydrate per 100 g. Fat and protein make up almost all of the calorie content.
That is why a pan-seared ribeye or grilled sirloin is a staple on keto and low-carb meal plans. The carb problem only starts when you add sugary sauces, flour coatings, honey glazes, or barbecue rubs. Even a modest spoonful of BBQ sauce can turn a zero-carb steak into a 5–10 g carb meal.
Carbs in Common Steak Add-Ons
| Add-on | Typical portion | Carbs (g) |
|---|---|---|
| Plain grilled steak | 100 g | 0 |
| Teriyaki sauce | 1 tbsp (15 ml) | 3 |
| Steak sauce | 1 tbsp (17 g) | 3 |
| BBQ sauce | 1 tbsp (16 g) | 5 |
| All-purpose flour coating | 1 tbsp (8 g) | 6 |
| Brown sugar dry rub | 1 tbsp (12 g) | 13 |
| Honey glaze | 1 tbsp (21 g) | 17 |
| Panko breading | 1/4 cup (30 g) | 22 |
These are typical values based on label averages and USDA reference data; always check the specific product label because sugar content varies widely between brands.
Worked Examples
Example 1 — Plain Sirloin. You cook a 400 g sirloin steak with just salt, pepper, and a little olive oil. Total added carbs = 0 g. Serving size = 150 g. Per 100 g = 0 g; serving carbs = 0 g. This is why plain steak is a keto favorite.
Example 2 — Teriyaki Flank Steak. You marinate a 350 g flank steak, and about 7 g of carbohydrate from the marinade remains on the meat after cooking. A 175 g serving would contain (7 ÷ 350) × 100 = 2 g carbs per 100 g, and 3.5 g in the serving. Still low, but not zero.
Example 3 — Breaded Cube Steak. A 500 g breaded steak contains roughly 28 g of carbs from the flour and breading. A 250 g serving gives (28 ÷ 500) × 100 = 5.6 g per 100 g, and 14 g for the serving. If you are on a strict under-20g keto plan, one breaded steak can use up a large portion of your allowance.
Tips for Accurate Carb Tracking
- Weigh the steak cooked, not raw. Meat loses 15–25% of its weight as water during cooking, so per-100g values are based on the cooked product.
- Only count marinade that remains on the meat. If a recipe says “discard excess marinade,” those carbs are not eaten.
- Use your own scale and the product label for sauces instead of relying on memory. “One serving” can be much smaller than you think.
- Log any flour, breadcrumbs, or cornstarch coating separately. A thin dusting might add only 2–3 g; a thick cutlet-style breading can add 15–25 g.
- If you’re also tracking protein for weight goals, pair this carb estimate with the protein for weight loss calculator.
Frequently Asked Questions
Does steak really have zero carbs?
Most government and USDA databases list cooked beef at 0 g carbohydrate per 100 g. Trace amounts of glycogen can remain, but they are negligible and do not meaningfully affect blood sugar or ketosis. The USDA FoodData Central is a reliable source for checking individual cuts.
Does cooking method make a difference?
Only if you add carbohydrate-containing ingredients. Grilling, pan-searing, roasting, and sous-vide add no carbs by themselves. Butter and oil also contain zero carbs. Flour dusting, breadcrumbs, honey, sugary rubs, and many bottled sauces are the only real sources.
Is this calculator suitable for all cuts?
Yes. Ribeye, sirloin, tenderloin, T-bone, flank, skirt, chuck, and New York strip all have essentially the same base carb content — zero. The tool’s math is about the ratio of added carbs to total cooked weight, so the cut does not change the calculation.
Why does per-100g change when I add sauce?
Because the total weight of the dish includes both steak and sauce. If you add sauce, the carb grams are spread across the total cooked weight. A heavy sauce applied to a light steak will raise per-100g carbs more than a small amount of sauce on a thick steak.
