Most TDEE calculators stop at calories per day. This one keeps going: enter your stats, choose a calorie deficit, and see the exact date you reach your goal weight. The tool uses the Mifflin–St Jeor equation for BMR, applies an activity multiplier for TDEE, then projects forward at 3,500 kcal/lb of fat loss with a sensible plateau adjustment. Same engine as the CalBurndown app — every formula and assumption is shown on the page, no spinner-screen 'premium plan' upsell.
A free NEAT estimator for Non-Exercise Activity Thermogenesis — the calories you burn from everything except sleep, food, and structured exercise. James Levine's research at the Mayo Clinic found up to 2,000 kcal/day of variance between people based purely on how much they fidget, pace, take stairs, and choose movement over stillness. This tool walks through job type, commute, household activity, fidget level, and standing time to produce a daily NEAT figure you can add to your BMR for a much more honest TDEE.
