How Many Calories Does A 6 Oz Steak Have? | Lean Facts

Calories change with the cut, how much fat you leave on, and the cooking setup. Six ounces cooked is a generous plate share at home and close to many restaurant portions. Below you’ll find clear numbers for popular cuts, then a simple way to ballpark any steak you cook.

Six-Ounce Steak Calories By Cut And Trim

Here’s the fast math most home cooks use: leaner cuts sit near the low end of the range, while richer cuts climb fast. The figures below come from lab data pulled from USDA sources. For instance, cooked top sirloin runs about 51 calories per ounce, while cooked tenderloin lands near 227 per 3 oz serving. Those two reference points frame the range for a typical dinner portion.

Estimated Calories For A 6-Ounce Cooked Portion

Cut (Cooked, Trimmed)	Calories (6 oz)	Notes
Top Sirloin (broiled)	~306 kcal	~51 kcal/oz from USDA-based data; lean profile.
Strip/New York (broiled)	~360–400 kcal	Varies by trim; mid-fat streaks. Data ranges from lean strip to standard.
Flank (broiled, lean)	~330–360 kcal	Lean muscle; tight grain; per-100g values convert to this range.
Tenderloin/Filet (broiled)	~454 kcal	USDA figure ~227 kcal per 3 oz; double for 6 oz.
Ribeye (lean filet, grilled)	~315–340 kcal	Lean-only ribeye filet; keeping the fat cap pushes calories higher.

Numbers shift because muscle and marbling change by cut. Top sirloin sits on the lean side. Strip and flank fall in the middle. Tenderloin tastes rich and often carries more calories at the same cooked weight. The lean ribeye filet entry above trims off the lip and cap; a classic ribeye with its fat edge will run higher per ounce.

When you want to track your day, it helps to anchor steak inside your daily calorie needs. Place your protein first, then build sides to match your target.

What Changes The Calorie Count In A Six-Ounce Steak

Cut And Marbling

Different muscles carry different fat patterns. Sirloin is lean with modest streaks. Strip keeps a firm bite and moderate fat. Tenderloin is buttery soft and often richer per ounce. Lean ribeye filet trims the fat cap; a full ribeye keeps it.

Raw Weight Vs. Cooked Weight

Heat drives off water, so cooked portions weigh less than raw. If you start with 8 ounces raw and finish at 6 ounces cooked, the calories per cooked ounce go up even if no extra fat is added. That’s why lab numbers label the cooking method and trim.

Trim And Prep

Shaving the edge fat drops calories fast. Leaving that edge on, or basting in butter, raises them. A teaspoon of oil adds about 40 calories; a tablespoon adds about 120. Searing with a slick of oil is fine; pour-over butter at the end changes the math.

Cooking Method

Broiling and grilling let some rendered fat drip away. Cast-iron searing holds drippings in the pan. Either way, the meat’s own fat still counts unless you trim it off the slice.

How To Ballpark Any 6-Ounce Portion

Step 1: Pick The Baseline

Use a per-ounce number tied to your cut and method. For cooked broiled top sirloin, the lab value is about 51 calories per ounce. That gives ~306 calories for six ounces. For cooked tenderloin, the label reads 227 per 3 ounces, so a six-ounce plate hits ~454.

Step 2: Adjust For Fat Left On

Kept the edge fat? Add 20–60 calories per portion, depending on how much stayed on the plate. Trimmed tight? Use the low end of the range.

Step 3: Add Cooking Fat If It Stays On The Steak

Used 1 teaspoon of oil for the pan and most stayed on the meat? Add ~40 calories. Basted with a tablespoon of butter? Add ~100–120. Brush-and-drip methods add less.

Lab Data You Can Trust

The figures above come from nutrient databases used by dietitians. You can view the exact entries at USDA FoodData Central and USDA-sourced pages such as the sirloin and ribeye filet entries hosted by MyFoodData. These pages show per-ounce and per-100-gram values with cooking method and trim specified.

Portion Sizes In Restaurants

Many menus pour on larger cuts. Eight to nine ounces cooked isn’t rare. Using the same math: a lean eight-ounce sirloin plate lands near ~408 calories before sauces. A richer eight-ounce tenderloin can reach ~605. Add butter finish or creamy sauce, and you’ll climb from there.

Fuel Planning For Goals

Keep Protein High Without Overshooting Calories

Pick cuts from the low-to-mid band. Sirloin, eye of round, and trimmed strip make it easy to hit protein targets while keeping calories steady.

Want A Richer Bite?

Go with tenderloin or a classic ribeye and keep the portion at six ounces cooked. Balance the plate with a baked potato and a big salad so the meal still fits your plan.

Cooking Method Impact On Six Ounces

Cooking style nudges the math. Here’s a simple view using common home methods. Values assume a mid-fat cut trimmed to standard butcher levels.

Cooking Method And Approximate Calories For 6 Oz Cooked

Method	Calories (6 oz)	What Changes
Grill/Broil	~330–380 kcal	Some rendered fat drips away; surface dries a bit.
Cast-Iron Sear	~350–410 kcal	Rendered fat stays in pan; more stays on the crust.
Pan Baste With Butter	~420–520+ kcal	Butter adds 100–120 kcal per Tbsp if it stays on the steak.

Reading Labels And Databases The Right Way

Match The Entry To Your Cut

Look for the exact cut and the exact prep: “cooked, broiled,” “grilled,” “trimmed to 1/8″ fat,” or “separable lean only.” Those phrases decide the number you’ll see. The top sirloin entry labeled “cooked, broiled, trimmed to 1/8″ fat” gives you the ~51 calories per ounce used earlier.

Use Per-Ounce Views For Quick Math

Per-ounce readouts help you scale to any plate. Multiply by six for a standard dinner portion, or by eight if you’re hungry.

Check A Second Source If You Change The Method

Switching from broil to pan-sear? Numbers move a bit. Browsing both the USDA listing and a clear per-ounce page keeps your math tidy.

Smart Swaps And Sides

Pick The Right Cut For The Day

Training day and you want more fuel? Tenderloin or a full ribeye fits. Rest day and you’re aiming lower? Sirloin or flank does the job, especially with a pile of roasted vegetables.

Balance The Plate

Pair steak with fiber-rich sides so the meal feels complete. That could be a baked potato, steamed greens, or a bright slaw. Sauces pack quick calories; a spoon of chimichurri adds far less than a ladle of cream sauce.
