Free nutrition calculators

Pick the right calculator for the decision in front of you.

Use the calculators to set a calorie target, choose a fat-loss pace, split macros, set protein, or sanity-check the week. When the number needs daily follow-through, move it into IntakeCalc.

next step into daily tracking when estimates become meals

Choose by goal

Start with the body problem you can picture.

Pick the lane that feels closest to real life. The calculators underneath it become the next move, not another list to browse.

Scene 01

Cut without panic math

A softer start for someone getting serious: post-workout, sweaty, strong, and ready to pick a target that does not wreck the week.

Scene 02

Beach-body maintenance

The performance lane: good shape, social confidence, trunks at the beach, and enough structure to keep muscle while life stays fun.

Scene 03

Check the meal before the next set

A lifter between bench sets checking macros on his phone, making the target feel like a normal training decision instead of spreadsheet homework.

Recommended path

A cleaner loop when the math gets messy.

Most people do not need every calculator at once. Work the loop: anchor the number, choose the target, turn it into meals, then judge the week.

A real planning scene keeps the sequence visual without turning the page into fake dashboard chrome.

01

Anchor

Find the number everything else depends on.

TDEE is the starting estimate. It tells you roughly what maintenance looks like before you decide whether the next phase is fat loss, maintenance, or a lean gain.

Use TDEE calculator
02

Target

Choose the pressure you can repeat.

A deficit only works if it fits real life. Use the deficit calculator to compare speed, weekly loss, and how aggressive the target feels before you commit.

Use deficit calculator
03

Meals

Translate the target into food decisions.

Macros and protein make a calorie number usable. They help you decide whether a meal is balanced or whether the day is drifting off target.

Use macro calculator
04

Reality check

Judge the week, not one messy day.

The weekly average calculator helps you see whether uneven days still fit the plan. Use it before you panic-adjust after one dinner, one weekend, or one missed target.

Use weekly average

Each page gives you an interactive calculator plus guidance on when to trust the number, when to adjust, and what to do next.

TDEE Calculator

Estimate maintenance calories, fat-loss calories, lean-gain calories, and a starting protein range from one practical TDEE calculator.

Best for: Starting a cut, maintenance phase, lean gain, or recomp from a clean calorie estimate.

Search intent: Find maintenance calories before choosing a fat-loss, recomp, or muscle-gain target.

Next: Then choose a deficit, protein target, or macro split.

BMR Calculator

Estimate basal metabolic rate, resting calories, and rough activity-adjusted calorie ranges before choosing a full daily target.

Best for:

Search intent: Find resting calories before adding activity level and choosing a TDEE-based target.

Body Fat Percentage Calculator

Estimate body fat percentage with the Navy tape method, then use lean mass context for protein, calorie, and macro planning.

Best for:

Search intent: Estimate body composition before choosing protein, fat-loss, or recomp targets.

Calorie Deficit Calculator

Turn maintenance calories into a realistic calorie deficit, weekly fat-loss estimate, and goal timeline.

Best for: Turning maintenance calories into a realistic fat-loss pace and daily target.

Search intent: Choose a daily calorie deficit after estimating maintenance calories.

Next: Then check whether the target still works across a real week.

Macro Calculator

Split any calorie target into protein, carbs, and fat for fat loss, maintenance, recomp, or muscle gain.

Best for: Splitting calories into protein, carbs, and fat when meal planning needs more structure.

Search intent: Turn a calorie target into macro grams for meal planning.

Next: Then use the app to compare meals against the target.

Split macros

Protein Intake Calculator

Find a practical daily protein target, useful range, and per-meal protein split from body weight and goal.

Best for: Setting a practical daily protein range and per-meal protein target.

Search intent: Set daily protein grams before building meals or choosing macros.

Next: Then build meals around the protein floor first.

Weekly Calorie Average Calculator

Average seven days of calories to see whether high and low days still fit your weekly calorie target.

Best for: Checking whether uneven high and low days still average out to the plan.

Search intent: Check weekly calorie average before overcorrecting after uneven eating days.

Next: Then adjust the next day calmly instead of overcorrecting.

Calculator FAQ

Common starting points.

Use these if you are not sure which calculator should answer the next decision.

Which calculator should I start with?

Start with the TDEE calculator if you do not know your maintenance calories. If you already know maintenance, jump to the calorie deficit calculator for fat loss, the protein calculator for a protein floor, or the macro calculator for a full split.

Start with TDEE
What should I use if I want to lose weight?

Use the TDEE calculator first, then the calorie deficit calculator. After you have a target, use the weekly calorie average calculator to make sure normal high and low days still fit the plan.

Choose a deficit
Do I need macros or just calories and protein?

Most people should start with calories and protein. Use the macro calculator when you want more control over carbs and fats for training, appetite, or meal planning.

Compare macros
When does the app matter?

The calculators help you pick the target. The app matters when you want to see whether today’s actual meals fit that target without rebuilding the math every time you eat.
