Method: Estimate BMR using an equation such as Mifflin–St Jeor (based on sex, weight, height, age), then multiply by an activity factor to estimate TDEE. Apply a goal factor (optional) for loss/gain.
Eating for your goals starts with knowing your daily calorie target. The Calorie Calculator helps you estimate daily calories quickly so you can plan meals without guesswork.
This calculator typically uses your body metrics and an activity level (and, if you choose, a goal such as maintenance, weight loss, or weight gain). From these inputs, it computes your estimated energy needs and shows a clear breakdown.
Calorie needs vary significantly between people due to factors like metabolism, activity, and consistency. While no calculator can replace medical guidance, using an evidence-based method is a strong starting point.
We focus on clarity: you’ll see the steps, the intermediate values (like BMR), and the final daily calorie recommendation. That transparency makes it easier to adjust if your weight changes over time.
You can use the results to design a simple meal plan, compare scenarios (different activity levels), and understand the impact of small changes.
The FAQ section addresses common questions—like how to choose an activity level and how fast results should be expected.

Answers to help you use the calculator correctly.
It’s an evidence-based estimate. Real needs vary—track progress and consider professional guidance for medical conditions.
Pick the closest day-to-day pattern. If you sit most of the day, choose light. If you have consistent active work or training, choose moderate or high.
Many people notice trends over 2–4 weeks. Use averages (weekly weigh-ins) rather than daily fluctuations.
Review your activity, portion sizes, and consistency. Small adjustments to calories may be needed.
Yes—maintenance calories are a sensible baseline for most planning.
