Calculators for your body and daily habits: TDEE and BMR calorie needs, body fat percentage, daily water intake, pregnancy due date and ovulation. Results are estimates for general reference — always follow your doctor's advice.
TDEE Calculator Find out how many Calories you burn in a day and how much to eat to lose fat, maintain or build muscle. Enter your stats in pounds and feet or in metric units; results include protein, fat and carb targets. Due Date Calculator Enter the first day of your last period, your conception date or your IVF transfer date to get your estimated due date, how far along you are today and the key prenatal dates ahead. Ovulation Calculator Enter the first day of your last period and your usual cycle length to estimate your ovulation day, your fertile window and your next period, with a color-coded calendar for the next 3 or 6 cycles. Body Fat Calculator Measure your neck and waist (plus hips for women) with a soft tape, and this calculator estimates your body fat percentage with the US Navy formula, along with your fat mass, lean mass and where you land on the ACE chart. Water Intake Calculator See roughly how much water to drink each day based on your weight, activity, exercise and the weather, in fluid ounces or milliliters, plus how many glasses that is and when to drink them.
