What you get, free

• Your maintenance calories (TDEE) — Mifflin-St Jeor, the equation used in clinical practice.
• A deficit that is safe — capped at 1% of bodyweight per week, with a floor so you are never told to eat dangerously little.
• Protein, fat and carbs in grams — protein set high enough to keep muscle while you lose fat.
• Your goal date — the honest number of weeks, including the weeks you spend not dieting.

Why most calculators are wrong about your goal date

They assume you diet in a straight line for six months. Nobody does. Appetite hormones fall, adherence slips, and the scale stalls around week 5. The plan this tool builds schedules diet breaks at week 5 and week 10 — full weeks at maintenance calories. You lose the same fat and you actually finish.
