Calorie Deficit Calculator

Find the daily calorie target you need to hit to lose weight at a chosen pace — the operational number that turns "I want to lose 5 kg" into "eat 1,950 kcal a day starting Monday." Enter your TDEE (maintenance calories) and the rate at which you want to lose weight, and the calculator returns the daily intake target along with a projected timeline.
