Maintenance Calorie Calculator

Maintenance calories are the calories you need each day to keep your weight stable. Calculate yours below, then see the resting baseline underneath it and the gradual loss and gain ranges around it.

Estimates your total daily energy expenditure (TDEE): the calories that keep your weight stable. For adults.

What are maintenance calories?

Maintenance calories are your estimated total daily energy expenditure, or TDEE. They combine resting energy needs with normal movement, exercise, and daily activity.

If your average intake matches maintenance, weight tends to stay stable over time. If you eat below it, you create a deficit. If you eat above it, you create a surplus.

Why maintenance comes first

Maintenance is the center point for most calorie goals. Weight loss and weight gain targets make more sense after you know the likely baseline, which is why the calculator above shows all three together.

For the full walkthrough — the Mifflin-St Jeor equation, the activity multipliers, and why a personalised number beats a generic target like 1,200 — read our TDEE calculator guide.

  • Maintain: stay near estimated TDEE.
  • Gradual loss: use a small deficit.
  • Gradual gain: use a small surplus.

Make the estimate practical

Coach Ivy helps you test your maintenance estimate in real life by tracking meals, calories, macros, water, and progress without making logging feel clinical.

Frequently asked questions

What are maintenance calories?

Maintenance calories are your estimated total daily energy expenditure (TDEE): the calories per day that keep your weight stable. Eating below creates a deficit; eating above creates a surplus.

How do I calculate maintenance calories?

Estimate your resting energy with the Mifflin-St Jeor equation, then multiply by an activity factor from 1.2 for sedentary up to 1.9 for extra active. This calculator does both steps.

How accurate is a maintenance calorie estimate?

Equations land within roughly 10 percent for most healthy adults, but individual needs vary. Treat the number as a starting point, track your average intake and weight for two to four weeks, then adjust from what actually happens.

Should I eat maintenance calories every day?

Weight responds to your average over time, not any single day. Normal variation around your maintenance number is expected and fine.
