The maintenance calorie calculator estimates daily calories to maintain your current weight (TDEE) using Mifflin–St Jeor BMR and an activity multiplier.
How to use
- Enter sex, age, height (cm), weight (kg).
- Pick your typical activity level.
- Read maintenance kcal; adjust for loss/gain on the calorie calculator or deficit calculator.
BMR vs TDEE
BMR is burn at rest; maintenance uses BMR × activity. See the BMR calculator for rest-only context.
Example
Male, 30 y, 170 cm, 70 kg, moderate → about 2,400–2,600 kcal/day (rounded).

Frequently asked questions
What are maintenance calories?
Maintenance calories approximate daily intake to hold your current weight at your activity level. Loss needs less; gain needs more.
How are maintenance calories calculated?
Mifflin–St Jeor BMR × activity factor. See the BMR calculator and TDEE calculator.
Same as the TDEE calculator?
Same formula family. This page highlights weight maintenance; use both tools with identical inputs to compare layout and BMR context.
Result doesn’t match real life?
Formulas are population averages—muscle, adaptation, and job matter. Tune using 2–4 week weight trends, not one day of eating.
What after maintenance?
Split meals on the macro calculator; deficits on the deficit calculator; protein-only on the protein calculator.
Is this medical advice?
No—results are for planning reference only. See clinicians for pregnancy, pediatrics, cycle disorders, or sleep conditions. Do not rely on calendar math alone for contraception.
