Daily Calorie Intake Calculator
About the Calorie Intake Calculator
The Daily Calorie Intake Calculator estimates how many calories you need each day to support your body and your goals—whether that’s weight loss, maintenance, or gain. By entering your age, gender identity, height, weight, and activity level, it calculates your Total Daily Energy Expenditure (TDEE) — the total number of calories you burn per day, combining both your resting metabolism and your daily movement.
It supports both metric and imperial units and includes identity-aware options for trans and non-binary users. You can also select a lean-mass–based formula (Katch–McArdle) for a composition-focused estimate, which is particularly useful for athletes or people whose bodies are changing through training or hormone therapy (HRT).
How to use your calorie results
Once you’ve entered your details and activity level, here’s how to use the results section depending on your goal:
Maintaining weight
If you simply want to maintain your current weight, leave the goal weight field empty.
You’ll see your daily calorie needs (TDEE) — the amount that keeps your weight stable based on your current activity.
Setting a weight goal
To lose or gain weight, enter your goal weight in the field that appears after selecting your goal.
This activates a full breakdown of Mild, Moderate, and Extreme calorie plans — each with its own estimated pace and finish date.
Understanding your plans
- Mild plan: Smaller daily adjustment, easier to sustain.
- Moderate plan: Balanced rate for steady progress.
- Extreme plan: Fastest route, but harder to maintain long term.
The calculator shows the estimated date you’ll reach your goal if you follow your chosen plan consistently.
Track and adjust
Use the Copy buttons to save your calorie targets. Track progress for 2–3 weeks and adjust if needed — real results depend on consistency, sleep, and activity.
Inclusive by Design: Trans & Non-Binary Options
Traditional calorie equations were built on cisgender data and use binary sex-based coefficients as indirect indicators of lean and fat mass. Because gender-affirming hormone therapy (HRT) can change body composition over time, this calculator lets you customize your identity for more accurate estimates:
- Select Trans Male (on HRT) or Trans Female (on HRT) to use coefficients that better reflect your physiology during or after transition.
- Choose Non-binary / Other for a balanced average that avoids binary assumptions.
- Use the Katch–McArdle option with body fat % for a neutral, composition-based result — especially effective during HRT changes or advanced training.
If you’re early in transition or unsure how your body composition is shifting, you can compare results from different settings (e.g., trans, non-binary, and Katch–McArdle) to view your calorie needs as a flexible range rather than a single number.

Turning calories into goals (and timelines)
To change body weight, adjust calories around your maintenance (TDEE). This tool offers three levels:
- Mild (~250 kcal/day) ≈ ~0.25 kg/week change
- Moderate (~500 kcal/day) ≈ ~0.5 kg/week change
- Aggressive (~1000 kcal/day) ≈ ~1.0 kg/week change
Faster is not always better. Larger deficits can be harder to sustain and may impact training quality, sleep, mood, or lean mass. Many people do best starting with a moderate adjustment and a protein-forward, fiber-rich diet while training regularly.
Which formula should I pick?
- Mifflin–St Jeor: Good default for most adults; performs well in validation studies.
- Harris–Benedict: Classic baseline; often close to Mifflin, sometimes a touch higher.
- Katch–McArdle: Best when you know body fat %; computes from lean mass and avoids sex-specific coefficients. Great for athletes or during transition.

Create your own WorkspaceQuick example
Suppose a 30-year-old, 75 kg, 183 cm person selects Moderately active and Mifflin–St Jeor. The calculator estimates BMR, scales it by activity to get TDEE (maintenance), then shows calorie targets for mild/moderate/aggressive loss or gain. If a goal weight is entered, it also projects a date estimate based on the weekly change rate.
How to use your number well
- Track outcomes for 2–3 weeks. If weight changes faster/slower than expected, nudge calories ±5–10%.
- Recalculate after significant weight or activity changes.
- Support lean mass: resistance training + adequate protein and sleep.
