Frequently asked questions

Answers to common searches around TDEE, maintenance calories, mortgage payments, percentages, age, and free online calculators.

What is the best free TDEE calculator for maintenance calories?

How do I calculate calories to maintain weight?

Start with a TDEE estimate. TDEE combines your basal metabolic rate with an activity multiplier to estimate calories burned per day. Maintenance calories are usually close to that number, but real needs can vary with training, body composition, health, and tracking accuracy.
