Quick answer: Daily Calorie Calculator
Estimate TDEE-style maintenance calories from age, sex, weight, height, activity.
Example: 32F, 165 lb, 5’5”, moderate activity → might land near 2,050 kcal maintenance; cut 400/day for ~0.8 lb/week loss trend.
Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
What this calculator does
- Daily Calorie Calculator
- Estimate daily calorie needs for maintenance or goals.
Formulas like Mifflin-St Jeor are population averages - wearables and lab tests personalize better. Treat output as a starting line for two weeks of logging, not gospel.
Calculate estimated daily calories from age, sex, weight, height, and activity level.
Inputs on this page: Age, Weight (kg), Height (cm), Sex. Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use Daily Calorie Calculator when you need a transparent daily calorie calculator answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) Age and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- Protein preserves muscle in a deficit - don’t cut it blindly.
- NEAT drops when you diet; expect plateaus and adjust.
- Medical conditions shift metabolism - consult pros if unsure.
How to use this tool
- 1Enter age, sex, weight, and height.
- 2Select your average activity level.
- 3Click calculate to estimate daily maintenance calories.
- 4Use the result to plan calorie deficit, maintenance, or surplus targets.

Key formula explained
How the calculation works
The Formula
TDEE estimated from BMR (Mifflin-St Jeor) × activity factor- Age: the value you enter for age.
- Weight (kg): the value you enter for weight kg.
- Height (cm): the value you enter for height cm.
- Sex: the value you enter for sex.
- Activity Level: the value you enter for activity.

What formula is used for calorie estimation?
This tool uses a standard BMR-based estimation with activity multiplier to estimate daily needs.
Can I use this for fat loss planning?
Yes, use maintenance estimate as a baseline, then apply moderate deficit targets.
Should I recalculate after weight changes?
Yes, recalculate as body weight and activity levels change.
Is this a medical recommendation?
No, this is a general estimate and not medical nutrition advice.
Can athletes use this calculator?
Yes for baseline planning, though sport-specific coaching may refine targets further.
Is this a medical nutrition plan?
No, it is a general estimation tool for planning purposes.
How fast should I reduce calories for fat loss?
Moderate deficits are usually more sustainable than aggressive cuts.
Can activity level selection change results a lot?
Yes, activity multiplier has a significant effect on estimated daily needs.
