Quick Answer: Your daily calorie needs depend on your age, weight, height, sex, and activity level. Use the calculator above to estimate your maintenance calories, then subtract 250–500 calories for weight loss or add 250–300 for muscle gain. Most people do well eating around 0.7–1.0 grams of protein per pound of goal body weight. Track for 10–14 days, then adjust based on real results.
Calorie Calculator: Find Your Daily Needs
How to use this page: Enter your details in the calculator above to get an estimate of your maintenance calories—the amount you'd need to keep your weight steady. Then choose a goal (lose, maintain, or gain), pick a macro preset that fits your preferences, and use the sample meals below to turn those numbers into plates you'll actually enjoy eating.

How to Read Your Results
The number you see is your estimated maintenance calories—roughly what your body burns in a day given your stats and activity level. Most calculators (including this one) use the Mifflin-St Jeor equation, which research shows is accurate within about 10% for most adults. It's not perfect, but it's a solid starting point.
If your goal is weight loss, you'll want to eat below maintenance. A deficit of 250–500 calories per day is sustainable for most people and translates to roughly 0.5–1 pound lost per week. Smaller deficits are easier to stick with and help preserve muscle—especially important if you're also strength training. For a deep dive into what to eat during a deficit, our Complete Guide to the Best Foods for Weight Loss covers the science behind food choices that keep you full on fewer calories.
If your goal is muscle gain, you'll need a modest surplus—typically 250–300 calories above maintenance—paired with progressive strength training 2–4 times per week. Eating more without lifting just adds body fat; the training signals your body to build muscle with those extra calories.
Protein target: Regardless of your goal, most people do well eating roughly 0.7–1.0 grams of protein per pound of goal body weight (or 1.6–2.2 g/kg). Protein preserves muscle during weight loss and supports muscle building during a surplus. Adjust based on your appetite and how you feel in workouts.

Choosing the Right Activity Level
Your activity multiplier has a big impact on your calorie estimate, so be honest with yourself here. Most people overestimate how active they are—and that leads to eating more than they need.
Sedentary means a desk job with minimal intentional exercise. If you work from home and your main movement is walking to the kitchen, this is you. Lightly active covers 1–3 short workouts per week or a job that involves some standing and walking. Moderately active fits 3–5 workouts weekly with a mix of lifting and cardio. Very active means 6–7 hard training sessions per week or a job that keeps you on your feet most of the day. Extra active is reserved for people with physical jobs who also train regularly—think construction workers who lift after their shift.
If you're between two levels, pick the lower one. It's much easier to add calories later if you're losing too fast than to chase down a too-high estimate that isn't producing results.
Set a Smart Goal (Deficit or Surplus)
Once you know your maintenance calories, the next step is deciding how much to adjust.
For weight loss: A conservative approach is maintenance minus 250 calories per day—slower progress, but easier to sustain and less likely to trigger intense hunger or energy crashes. The standard approach is maintenance minus 500 calories per day, which works out to roughly 1 pound per week in theory (though individual results vary based on metabolism, water retention, and consistency).
For muscle gain: A lean bulk typically means maintenance plus 250–300 calories per day, combined with progressive strength training. This minimizes fat gain while providing enough energy to build muscle. For a complete training and nutrition approach, our Exercise Guide for Weight Loss covers how to structure workouts alongside your nutrition plan.

Macro Presets for Popular Calorie Targets
Pick the style you'll actually stick with—the "best" macro split is the one you can maintain. All three presets below include adequate protein and leave room for plenty of vegetables and whole foods. Adjust by 5–10% based on your energy levels and workout performance.

Plate Templates & Sample Days
Numbers are useful, but what does a calorie target actually look like on a plate? Here's a simple formula that works across most calorie levels:
The plate formula: 4–6 oz lean protein + 1–2 cups vegetables + ½–1 cup smart carbs (rice, potatoes, beans, whole grains) + 1–2 tsp added fats (olive oil, butter, cheese). Scale portions up or down based on your calorie target.
Sample day at ~1,800 calories:
Breakfast: Greek yogurt bowl with berries and measured granola (about 400 cal). Oatmeal or Overnight Oats are another solid option.
Lunch: Salmon rice bowl with roasted vegetables (about 500 cal). See our salmon guide for why fatty fish works well for weight management.
Dinner: Chicken breast with roasted sweet potatoes and sautéed greens (about 550 cal). Sweet potatoes add fiber and volume without excess calories.
Snacks: Cottage cheese with fruit (see why it works) or an apple with measured peanut butter (PB portions matter)—about 350 cal total.

Troubleshooting Stalls (The 10-Day Check)
Weight loss isn't always linear. Water retention, sleep quality, stress, and hormonal fluctuations can all mask fat loss on the scale. Before panicking, give any new calorie target at least 10–14 days to show results.
If progress stalls after two weeks, run through this checklist:
Log honestly for 7–10 days—including weekends, cooking oils, dressings, and that handful of nuts you grabbed while making dinner. These "invisible" calories add up faster than most people realize.
Average your scale weight over those 7–10 days rather than fixating on any single weigh-in. Daily weights fluctuate; the trend matters more than the number.
Adjust one dial at a time: Either reduce portions by 100–200 calories per day, or add 2,000–3,000 extra steps daily. Don't do both at once—you want to know what's working.
Protect your muscle: Keep protein high and maintain your strength training. Losing weight too aggressively or skipping resistance exercise leads to muscle loss, which slows your metabolism and makes keeping weight off harder long-term.
Frequently Asked Questions
How accurate is a calorie calculator?
It's an estimate based on population averages—useful as a starting point, but not gospel. Your actual needs depend on your muscle mass, daily movement patterns, metabolic adaptation, and consistency. The calculators using the Mifflin-St Jeor equation tend to be within about 10% for most people. Track for 10–14 days and adjust based on what the scale and mirror tell you.
How big should my calorie deficit be?
Start modest—250–500 calories below maintenance. Larger deficits (800+ calories) are harder to sustain, more likely to trigger intense hunger, and more likely to cause muscle loss. A slower approach is almost always more sustainable.
Do I need to count macros or just calories?
Calories determine whether you gain, lose, or maintain weight. Macros—especially protein—determine how you feel, how you perform in workouts, and whether you preserve muscle during weight loss. Many people do well with a simple approach: hit a protein target, use the plate formula, and let the rest fall into place.
How often should I recalculate?
Every 8–12 weeks, or whenever your weight or activity level changes significantly. As you lose weight, your body requires fewer calories to maintain itself, so your maintenance number will gradually decrease.
Can I lose fat without doing cardio?
Absolutely. Fat loss comes from a calorie deficit, not from any specific type of exercise. That said, cardio and daily steps burn additional calories, improve cardiovascular health, and let you eat a bit more while still losing. Strength training is arguably more important—it protects muscle mass, which keeps your metabolism healthy.
