Calorie Deficit Calculator

Compare maintenance calories and target intake, then estimate the daily gap, weekly deficit, and rough weekly weight change before you commit to a cutting plan.

Use this page once maintenance calories are already known or estimated. It is for planning, not for medical diagnosis.

Pressure-test a calorie target before you lock macros

This page sits between a full calorie planner and a macro calculator. It answers one question only: how large is the intake gap you are about to use?

Enter maintenance calories and a target calorie intake.

How to choose between nearby pages

Use BMR & TDEE or Calorie & Weight-loss Planner if maintenance calories or the target itself are not fixed yet. Use Calorie Surplus when the real question is gaining above maintenance. Use this page when both numbers are already known and you want to pressure-test a cutting gap. After the daily target looks realistic, move to Meal Calorie Split for meal execution, then to protein or macro pages. Once the daily PFC totals are fixed, use Macro Per Meal for the final meal-by-meal execution table.

FAQ

What does this page calculate?

It compares maintenance calories and target intake, then estimates the daily calorie gap, weekly calorie gap, and rough weekly weight change in kg and lb.

Is the weekly weight-change value exact?

No. It is a rough planning estimate using common calorie-per-weight-change rules of thumb. Real changes vary with adherence, water balance, and metabolism.

When should I use this instead of a calorie planner?

Use this page when you already have a maintenance estimate and want to pressure-test a target intake. Use a calorie planner when maintenance or target calories still need to be estimated first.

Does this page provide medical advice?

No. It is a simple planning aid only. Use qualified medical or dietetic guidance for personalized care.
