Useful for
Set a maintenance calorie target
Measurement units
BMR1,239 kcal
Estimated resting calorie needs.
TDEE maintenance calories1,920 kcal
Moderate activity, 3-5 days/week
Daily calorie target1,728 kcal
About 10% below TDEE, often easier to sustain while keeping training performance.
Adjustment from TDEE-10%
About 192 kcal per day and 1,344 kcal per week compared with TDEE.
Use calorie targets as a starting point, then adjust gradually with weight, waist, training, and food records.
Quick answer
Set a starting calorie target for maintenance, loss, or gain
Estimate TDEE, then apply a selected maintenance, calorie-deficit, or calorie-surplus goal to get a practical daily starting target.
It does not create a meal plan or replace individualized medical or nutrition advice, especially for higher-risk situations.

Health information notice
Daily calorie targets are planning estimates, not personal medical or nutrition advice. Avoid aggressive dieting and consult a qualified professional for pregnancy, minors, medical conditions, medication use, eating disorder history, or rapid weight change.
How to use it
- Choose US customary or metric units, then enter body measurements and activity level.
- Choose maintenance, fat loss, or weight gain.
- Review the daily target, TDEE adjustment, worked example, and limitations.
Common use cases
- Set a maintenance calorie target
- Estimate a conservative fat-loss target
- Plan a moderate weight-gain target
Conservative Calorie Target Planning
The safest way to use a calorie target is to treat it as a starting estimate. Track real-world changes for a few weeks, then adjust gradually rather than making extreme jumps.
| Goal | Typical adjustment | Practical reminder |
|---|---|---|
| Maintain weight | Around TDEE | Useful for building a food record baseline. |
| Mild fat loss | About 10% below TDEE | Often easier to sustain. |
| Standard fat loss | About 20% below TDEE | Avoid aggressive dieting or rapid loss. |
| Lean gain | About 10% above TDEE | Useful when training performance matters. |
| Weight gain | About 15% above TDEE | Adjust if gain is faster than intended. |
Worked Daily Calorie Target Example
If estimated TDEE is 2,100 kcal per day, maintenance remains about 2,100. A mild 10% reduction gives about 1,890 kcal, while a 10% surplus gives about 2,310 kcal. These are planning estimates, not guaranteed rates of weight change.
| Selected goal | Calculation from 2,100 kcal TDEE | Starting estimate |
|---|---|---|
| Maintain | 2,100 x 1.00 | 2,100 kcal/day |
| Mild fat loss | 2,100 x 0.90 | 1,890 kcal/day |
| Standard fat loss | 2,100 x 0.80 | 1,680 kcal/day |
| Lean gain | 2,100 x 1.10 | 2,310 kcal/day |
When a Simple Percentage Target Is Not Enough
The calculator assumes a fixed percentage above or below TDEE. Real calorie needs can change with body weight, activity, medication, illness, pregnancy, and other factors. A dynamic planning tool or qualified professional may be more appropriate when the goal is time-sensitive or medically important.
| Situation | Use this result? | Better next step |
|---|---|---|
| General adult planning | As a starting estimate | Track food, activity, and weight trends for two to four weeks. |
| Under 18, pregnant, or breastfeeding | No | Use age- and situation-specific professional guidance. |
| Medical condition, medication, or eating-disorder concern | Not on its own | Consult a qualified health professional. |
| Goal weight by a specific date | Limited | Use the NIH Body Weight Planner or professional support. |
FAQ
Is this a diet prescription?
No. It is a planning estimate based on BMR, TDEE, and a goal adjustment.
How should I use the result?
Treat it as a starting point and adjust gradually using body weight, waist, training, and food records.
