TDEE Calculator - Free Online Tool

TDEE Calculator helps you find your total daily energy expenditure — the calories your body burns in a day — from your body metrics and activity. Enter the required values, review the result instantly, and adjust the inputs until the number matches the decision you are making. The tool is designed for quick checks on mobile or desktop, with clear labels, practical examples, and no account required.

TDEE Calculator

Gender

Age (years)

Weight (kg)

Height (cm)

Your activity level

Enter your age, weight, and height to see your BMR and TDEE across every activity level.

TDEE is your BMR (calories burned at complete rest) multiplied by an activity factor. The BMR here uses the Mifflin-St Jeor equation. These figures are estimates for planning, not medical advice.

What is TDEE Calculator?

TDEE Calculator is a free online calculator for people who need a fast, readable answer without opening a spreadsheet. Enter your gender, age, weight in kilograms, and height in centimetres, then pick your activity level. The tool shows your BMR and your TDEE at every activity level for comparison. The page keeps the inputs visible above the result, so you can change one value and immediately see how the final number moves. That makes it useful for founders, freelancers, students, marketers, operations teams, and anyone preparing a simple estimate during a conversation.

The calculator follows the same lightweight pattern as the other free tools on RohanSurve.in: it uses plain inputs, a compact result card, and explanatory sections below the widget. TDEE equals BMR multiplied by an activity factor; BMR uses the Mifflin-St Jeor equation (10 × weight in kg + 6.25 × height in cm − 5 × age, then +5 for men or −161 for women), and the activity factor ranges from 1.2 (sedentary) to 1.9 (extra active). The goal is not to replace a full finance model or analytics dashboard. It is to give you the reliable first-pass number you need before you decide whether a deeper spreadsheet, invoice, report, or official document is worth preparing.

The calculation runs entirely in your browser. Your age, weight, height, and other details are not uploaded to a server. You can paste or type draft numbers freely, clear the fields, and repeat the calculation as many times as needed. For Indian users, money-related examples use ₹ formatting and practical business language so the output feels familiar for invoices, ecommerce offers, agency retainers, ad budgets, and small-business planning.

How to Use This TDEE Calculator

Open TDEE Calculator and read the field labels before entering values. Each field is intentionally named around the business question the calculator answers.
Type the first value exactly as you know it. For money fields, enter the number only; the result card will format the output with the right context.
Enter the second value or date, depending on the calculator. The result appears automatically once the inputs are valid.
Review the highlighted answer first, then scan the supporting breakdown for totals, rates, or intermediate values.
Change one input at a time to compare scenarios. This is useful when checking best-case, normal, and conservative assumptions.
Use the example and FAQ sections below the tool if you are unsure which value should go into which field.

Why Use This TDEE Calculator?

Use TDEE Calculator when you need an answer quickly and do not want to build a spreadsheet for a small calculation.
The interface keeps calculations transparent by showing the main result plus supporting values instead of hiding everything behind a single number.
Inputs and outputs are formatted for everyday business use, including Indian number formatting and ₹ examples where money is involved.
The tool is browser-based, so there is no signup flow, installation step, or API key to manage.
Because the result updates as values change, it works well for comparison, planning, and teaching basic calculation logic.
The surrounding guide explains the formula, common mistakes, and practical situations where the calculator is helpful.

When to Use TDEE Calculator

People planning a diet find their maintenance calorie level before setting a deficit or surplus.
Lifters and athletes size their intake to support training volume and recovery.
Anyone comparing how much activity level changes their daily burn sees the full range at once.
Coaches explain to clients why a desk worker and an active worker need different intakes.
People tracking macros start from an accurate calorie baseline before splitting protein, carbs, and fat.

TDEE Calculator Features

All activity levels at once

See your TDEE for sedentary through extra active in one table, so the impact of activity is obvious.

BMR and TDEE shown together

The calorie burn at rest and the total daily burn are displayed side by side for context.

Mifflin-St Jeor BMR

Uses the modern equation recommended for the best accuracy across body types.

Instant comparison

Change any input and every activity-level figure recalculates immediately.

Understanding TDEE Calculator Results

TDEE Calculator is most useful when the input values are simple and the question is well defined. The result should be treated as a decision aid: it helps you understand a relationship between values, estimate an outcome, or verify a number someone shared with you. If the calculation affects tax filings, payroll, legal documents, or audited financial statements, use this result as a quick check and confirm the final number in your official workflow.

The core formula is: TDEE equals BMR multiplied by an activity factor; BMR uses the Mifflin-St Jeor equation (10 × weight in kg + 6.25 × height in cm − 5 × age, then +5 for men or −161 for women), and the activity factor ranges from 1.2 (sedentary) to 1.9 (extra active). This formula is intentionally shown in plain language because many mistakes happen when people mix up base values, totals, percentages, and time periods. Reading the formula once before entering data usually prevents the most common errors and makes the output easier to explain to a client, teammate, or manager.

Example

Moderately active adult

Input

male, 30 years, 70 kg, 175 cm, moderately active

Output

BMR ≈ 1,649 kcal; TDEE ≈ 2,556 kcal/day

TDEE is the number to eat at to maintain weight. A deficit below it loses weight; a surplus gains it.

TDEE Calculator Best Practices

Choose activity conservatively

People tend to overrate activity. If your job is mostly seated, do not pick a high level just because you train a few times a week.

Use TDEE as a baseline, not a rule

It is a starting estimate. Track your weight for two to three weeks and adjust the number to what actually maintains it.

Recalculate as your weight changes

TDEE falls as you lose weight and rises as you gain, so update the inputs periodically.

Pair it with goals

Once you know TDEE, subtract for fat loss or add for muscle gain. The Calorie Calculator turns TDEE into goal targets.

Common TDEE Calculator Mistakes

Confusing BMR with TDEE

BMR is calories burned at complete rest. TDEE includes daily movement and exercise, so eating at BMR is almost always too little.

Overstating activity level

An activity factor that is too high inflates TDEE and stalls fat loss. When unsure, pick one level lower.

Using imperial units

Enter weight in kilograms and height in centimetres. Pounds and inches will give incorrect results.

FAQs

Is TDEE Calculator free to use?

Yes. TDEE Calculator is free to use in your browser, with no signup, no installation, and no API key required.

Does TDEE Calculator store my inputs?

No. The calculation runs locally in the browser. Your entered values are not intentionally uploaded for the calculation.

Can I use decimals?

Yes. Numeric fields accept decimal values where decimals make sense. For dates, use the browser date picker so the calculator can read the value consistently.

When should I use a spreadsheet instead?

Use a spreadsheet when you need many rows, chained formulas, approvals, audit history, or a calculation that depends on several changing assumptions.

TDEE Calculator gives you a fast, practical result without setup, so you can move from guessing to checking in a few seconds.
