Very Active TDEE Calculator
Find your Total Daily Energy Expenditure for hard training six or seven days a week — pre-set to the very active (1.725) factor. Adjust the level any time.
Calculate BMR & TDEE
Required: the BMR formula uses biological sex (male or female) as a variable, so the estimate can’t be calculated without it.
Range: 15–100 years
Range: 30–300 kg · up to 2 decimals
Enter your height in centimeters (e.g., 170 cm)
Range: 100–250 cm
Mifflin-St Jeor is pre-selected — validated as the most accurate formula for the widest range of adults in modern research.

Quick Answer
What the Very Active Setting Means
This calculator is pre-set to the very active (1.725) activity factor. Enter your sex, age, height and weight and it returns your Basal Metabolic Rate, then multiplies that by 1.725 to give a Total Daily Energy Expenditure well above your resting burn — the maintenance calories for someone training hard most days. You can change the activity level at any time if your week looks different.
What the 1.725 Tier Covers
The very active factor of 1.725 sits one step below the top of the activity scale, and it describes a genuinely demanding week: hard training on six or seven days, or a physically heavy job layered on top of regular workouts. It is the setting for people whose movement is not an occasional add-on but a daily feature of their lives — distance runners in a build phase, lifters training most mornings, tradespeople on their feet who also lift after work. Because the multiplier is applied to your resting metabolic rate, the resulting Total Daily Energy Expenditure sits well above your bare Basal Metabolic Rate; a large block of activity calories has effectively been folded into that single number. The arithmetic itself is plain — the calculator works out your BMR from sex, age, height and weight, then multiplies it by 1.725 to reach the day’s total. What you are choosing when you pick this tier is not a different formula but a bigger activity assumption, and that assumption is doing a lot of work. The gap between a sedentary factor of 1.2 and a very active 1.725 can be several hundred calories a day on the same body, which is exactly why the tier you select deserves as much honesty as the measurements you type in above it.
The Double-Counting Trap
Here is the mistake that quietly wrecks more plans than any other. The 1.725 multiplier already includes your training — that is the entire point of an activity factor — so once you have read your very active TDEE you must not also add the calories your watch logged for today’s session on top of it. Doing both counts the same hour of exercise twice and inflates your target by exactly the amount you were trying to account for, which turns a tidy maintenance figure into a number you will struggle to outrun. The rule is simple and it only allows one of two routes. Either pick the activity tier that matches your week — very active, in this case — and stop there, treating the TDEE as the complete daily figure with nothing further to add. Or set the calculator to the sedentary tier instead, take that lower baseline, and add each workout’s burn back in yourself, session by session. Both routes arrive at a defensible number; mixing them does not. If you prefer the second, build-it-up approach, the Calories Burned Calculator gives you a per-session figure to add to a sedentary baseline. What you cannot do is take a very active TDEE and then bolt those same burned calories on top, because the multiplier has already spent them for you.
Pick the Tier That Matches Your Real Week
The most common reason a TDEE reads too high is not a faulty formula but an optimistic activity tier. Be honest about the whole week rather than your best day in it: a few solid gym sessions among otherwise ordinary days is usually “moderately active” at 1.55, not very active at 1.725. The difference matters because overstating the tier inflates your maintenance figure, and a maintenance figure that runs a few hundred calories high quietly erases a deficit you genuinely meant to keep — you eat to a number that was never really yours. When you are unsure which tier you belong in, choose the lower one. It costs you nothing to be conservative, and two weeks of real weight data will confirm the figure or nudge you up a tier with far more authority than a guess made on day one. Once you have a daily total you trust, the Macro Calculator splits a high intake into protein, carbohydrate and fat targets that support hard training. And if you want to see every activity tier laid out side by side rather than locked to this one, the TDEE Calculator is the full tool this page is built from. These figures are general estimates for healthy adults, not medical advice.
BMR is estimated with the Mifflin-St Jeor equation (1990); activity multipliers follow ACSM / ACE guidance. All formulas carry a ±10–15% margin against laboratory measurement and do not account for individual medical conditions. Individual needs vary.
