Tracking tuna by the tablespoon is handy when you are making a tuna salad, poke bowl, or high-protein lunch and want a quick calorie estimate. This calculator converts your spoonfuls into calories, protein, and fat using the nutritional profile of common tuna types — canned light or white tuna packed in water or oil, plus raw yellowfin and skipjack.
Whether you are counting calories, following a macro plan, or just curious about your tuna salad, the tool lets you adjust the number of tablespoons and the assumed weight per tablespoon (default 15 g). Since flaked tuna can pack loosely or densely, you can fine-tune the gram value to match your measuring style.
Results include a per-tablespoon breakdown and total nutrition for your serving, so you can log the numbers with confidence. Use the preset buttons for common portions like 2 tbsp or ¼ cup, and switch tuna types to see how much the calorie count changes.
🍣 Tuna Calories per Tablespoon
Estimate calories, protein, and fat for any spoonful of tuna — choose your type and portion below.
A level tablespoon of flaked tuna usually weighs about 15 g, but it can range from 10–20 g depending on packing and chunk size.

Step-by-Step Guide
- Choose the tuna type that matches what you are eating — canned light, white/albacore, or a raw variety.
- Enter the number of tablespoons, or tap a preset portion like 2 tbsp or ¼ cup.
- Adjust grams per tablespoon if your spoonful packs heavier or lighter than 15 g, then press Calculate.

Nutrition Values Used in This Calculator
The tool uses typical per-100-gram values for drained canned tuna and raw fresh tuna. These figures are adapted from USDA FoodData Central, which lists a range of values depending on brand, pack, and sampling.
| Tuna type | Calories per 100 g | Protein per 100 g | Fat per 100 g |
|---|---|---|---|
| Canned light in water (drained) | 116 kcal | 25.5 g | 0.8 g |
| Canned white/albacore in water (drained) | 128 kcal | 24.0 g | 2.5 g |
| Canned light in oil (drained) | 198 kcal | 29.0 g | 8.2 g |
| Raw yellowfin | 109 kcal | 24.0 g | 1.0 g |
| Raw skipjack | 103 kcal | 22.0 g | 1.2 g |

Worked Example
Example: You measure 3 level tablespoons of canned light tuna in water. If each tablespoon weighs 15 g, your serving is 45 g.
- Calories: 116 × 45 ÷ 100 = 52.2 kcal
- Protein: 25.5 × 45 ÷ 100 = 11.5 g
- Fat: 0.8 × 45 ÷ 100 = 0.4 g
If the same 3 tablespoons are oil-packed, the total rises to about 89 kcal because the per-100-g calorie value is much higher.
Tips for Better Estimates
- Use a dry, level tablespoon rather than a heaping spoon — heaping portions can add 30–50% more tuna.
- Drain canned tuna well before measuring; water or oil left in the can adds weight without helping your macro count.
- If you weigh your food, use grams instead: 1 tbsp is usually about 15 g, but a scale gives the exact number.
- For recipes, remember that mayonnaise, yogurt, or other mix-ins add calories and should be logged separately.
Factors That Affect Accuracy
Calorie counts for canned tuna vary by brand, liquid pack, and draining method. Oil-packed tuna retains some oil even when drained, which can raise the fat and calorie counts. The values here are close averages, not a guarantee for a specific can. For precise tracking, check the nutrition label on your product or search its exact entry in USDA FoodData Central.
Frequently Asked Questions
Why does oil-packed tuna have so many more calories? Tuna is naturally lean; most extra calories come from absorbed oil. Draining and rinsing can reduce the amount of oil left on the fish.
Can I use this for tuna salad with mayonnaise? No — this calculator only estimates the tuna portion. Add your mayo, celery, or other ingredients separately to get the full meal total.
What if my tablespoon is heaped? A heaped tablespoon can weigh closer to 20–25 g. Increase the grams per tablespoon field or, better, weigh your portion once to learn your typical spoon size.
