Most adults maintain weight somewhere around 1,800–2,600 calories/day, depending on body size and activity. Use the calculator for a more personal estimate.
Average calories per day: simple ranges
The “average calories per day” depends on body size, activity level, and goal. As simple starting ranges, less active adults may fall around 1,600–2,200 calories/day, moderately active adults around 2,000–2,600 calories/day, and highly active adults around 2,400–3,000+ calories/day.
How to use the estimate
Use the result as a starting point, then adjust based on 2–4 weeks of progress. If weight is moving too fast or too slowly, change the target gradually instead of making extreme cuts.
Tracking tip
Daily targets work best when you track meals consistently and compare weekly averages, not single days.
Frequently Asked Questions
Is the calculator medical advice?
No. It is a practical estimate for general tracking and should not replace advice from a doctor or registered dietitian.
Why does my real maintenance differ?
Real maintenance changes with movement, muscle mass, sleep, hormones, food tracking accuracy, and normal water weight changes.
What deficit should I start with?
A moderate deficit is usually easier to maintain than an aggressive one. Many people start around 250–500 calories below maintenance.
