calorie deficit calculadora — the short version

We built Calorie Deficit calculadora because the other tools for this job either cost a subscription or came with a consent banner the size of a small novel.

If a value drops into a red band, act; if it is borderline, track. Measure at the same time of day for consistency — then work out the number and the rest of this page explains what the answer means.

Work out the daily calorie deficit needed to lose weight at a safe rate of 0.5–1 kg per week, from TDEE and target loss.

A worked example, step by step

Consider a realistic scenario and follow it through:

Work out the daily calorie deficit needed to lose weight at a safe rate of 0.5–1 kg per week, from TDEE and target loss.

When to use this calculadora

Calorie Deficit calculadora is aimed at people arriving with questions like these:

"Calorie deficit to lose 1lb"
"Daily calorie deficit"
"Weight loss calculadora"
"What is calorie deficit"
"How to calculate calorie deficit"
"Calorie deficit formula"

When to reach for something else

Every tool has an edge where it stops being the right answer. Calorie Deficit calculadora is no exception:

For legally binding tax or medical decisions — cross-check with HMRC, NHS or a qualified professional.
For very large or very small extremes the rounding error outgrows the useful precision.
When the underlying rate or threshold has changed since the page was last reviewed — always verify with the primary source.
When the input you have is already a derived figure (net of something) — feeding it in as "gross" will double-subtract.

Five things that trip everyone up

Every time you work out the number for a new scenario, one of these creeps in — it's worth knowing them ahead of time.

Entering a monthly figure into an annual field (or vice versa).
Forgetting a leading zero on decimals (.5 instead of 0.5 breaks some inputs).
Trusting a single reading when the underlying number naturally fluctuates.
Comparing two answers that used different assumptions — always re-run both.
Skipping the formula box. If you don’t understand the method, the answer is just a vibe.

The sources behind the numbers

Where the maths needs an external authority, we cross-check against:

NHS
WHO
Harvard T.H. Chan

Works well alongside

If this question keeps coming up for you, the same cluster of tools usually comes next:

BMR calculadora — Estimate your Basal Metabolic Rate — the calories your body burns at rest — with the Mifflin-St Jeor equation.
TDEE calculadora — Work out Total Daily Energy Expenditure based on BMR and activity level to set a calorie target.
Macronutrient calculadora — Split your daily calories into protein, carbs and fat in grams, based on your body weight and training goal.
Protein Intake calculadora — Work out daily protein needs in grams using body weight, activity level and training goal (fat loss, maintenance, muscle gain).
