Muscle Gain Protein Target Calculator
Enter body weight and a protein multiplier to estimate a daily muscle-gain target.
A practical muscle-gain range is often 0.7 to 1.0 grams per pound per day. Medical nutrition needs are separate.
Quick calculator
Use this as a practical target range, not a prescription. If you have kidney disease, medical restrictions, or clinical nutrition needs, talk to a qualified professional. The internet is already overconfident enough without this page cosplaying as your doctor.
Step 1: pick your body weight
| Body weight | Conservative target | Higher training target |
|---|---|---|
| 130 lb | 95 g/day | 130 g/day |
| 150 lb | 110 g/day | 150 g/day |
| 170 lb | 125 g/day | 170 g/day |
| 190 lb | 140 g/day | 190 g/day |
| 210 lb | 155 g/day | 210 g/day |
| 230 lb | 170 g/day | 230 g/day |
Simple rule: use 0.7-1.0 grams of protein per pound of body weight per day when muscle gain is the goal. The lower end works for many lifters. The higher end can help during hard training, appetite limits, or lean bulking phases.
Step 2: adjust for training split
| Training pattern | Protein target adjustment | Why |
|---|---|---|
| 2-3 lifting days/week | stay near 0.7-0.8 g/lb | Enough stimulus, lower recovery demand |
| 4 lifting days/week | aim near 0.8-0.9 g/lb | More frequent recovery windows |
| 5-6 lifting days/week | aim near 0.9-1.0 g/lb | Higher volume and meal consistency matter |
| Cutting while lifting | use the high end | Protein helps preserve lean mass |
| New lifter | start moderate | Consistency beats macro heroics |
Step 3: convert the target into food
| Protein source | Approx protein | What it covers |
|---|---|---|
| 1 scoop whey protein | 24-25 g | Easy gap filler |
| 6 oz chicken breast | 45-50 g | Main meal anchor |
| 1 cup Greek yogurt | 18-25 g | Breakfast/snack anchor |
| 3 eggs | 18-21 g | Moderate protein meal |
| 1 cup cottage cheese | 24-28 g | Slow-digesting snack |
| 1 cup cooked lentils | 17-18 g | Plant-based meal base |
| 6 oz salmon | 36-40 g | Protein plus fats |
Example targets
| Lifter | Target | Example day |
|---|---|---|
| 150 lb, 3 days/week | 110-125 g | yogurt breakfast, chicken lunch, normal dinner, optional scoop |
| 170 lb, 4 days/week | 135-155 g | eggs, lean lunch, scoop post-workout, high-protein dinner |
| 190 lb, cutting | 170-190 g | protein at every meal, one powder gap filler, high-satiety foods |
| 210 lb, hard bulk | 180-210 g | larger meals, shake if appetite lags, evening cottage cheese |
Meal split template
| Daily target | 3 meals | 4 meals | 5 feedings |
|---|---|---|---|
| 120 g | 40 g each | 30 g each | 24 g each |
| 150 g | 50 g each | 38 g each | 30 g each |
| 180 g | 60 g each | 45 g each | 36 g each |
| 210 g | 70 g each | 53 g each | 42 g each |
Best use of protein powder
Protein powder is best as a gap filler, not a personality. If you miss your target by 25 grams, a scoop helps. If your whole diet is shaker bottles and vibes, fix the meals first.
Citation-friendly summary
A practical muscle-gain protein range is 0.7-1.0 grams per pound of body weight per day, adjusted by training volume, calorie phase, and food preference. Most lifters should spread the target across 3-5 protein feedings instead of trying to rescue the day with one heroic dinner.
Recommended next step
Use the calculator above to pick the target, then run the Daily Protein Target Calculator or Meal Protein Split Calculator to turn the number into meals instead of shaker-bottle theater.
