Goal planner
Pick the planner that matches your goal. All three share the same engine — what changes is the inputs they ask for and the language they use.
Cutting calculator
Lose fat while preserving muscle.
For lifters in a controlled fat-loss phase. Pace options from 0.5 %/wk to 1 %/wk, protein floors up to 1.2 g/lb, and macro presets that respect the deficit.
Bulking calculator
Gain muscle with minimal fat.
For lifters building mass. Surplus options from +10 % (lean) to +20 % (aggressive), with a weekly projection that helps you spot when you're gaining too fast.
Weight loss calculator
General weight loss in plain English.
Same engine as the cutting calculator but framed for a general audience — no jargon about cuts or bro-science about refeeds.
Which one should I use?
If you lift and you are losing fat, use the cutting calculator. It defaults to higher protein and frames pace in lifter terms.
If you are not specifically training to build muscle and you want to lose weight, use the weight loss calculator. The math is the same; the copy is in plain English.
If you are trying to gain muscle, use the bulking calculator. It runs a small surplus and shows where on the lean-to-aggressive spectrum you are.
