Estimate your body fat percentage, BMR, TDEE daily calories, BMI, healthy weight range, and muscle index in seconds — free, no calipers or tape measure required. Formulas estimate; only a DEXA scan at our downtown Denver clinic measures your true body composition.
Estimate only: your true body fat is likely between 16.2% and 24.2%. Only a DEXA scan can tell you exactly.
Calculated using lean body mass index algorithms.
These numbers are formula estimates with a ±5–8% error margin — they can't see your muscle, bone, or visceral fat. A 7-minute DEXA scan measures your real body composition.

A DEXA Scan is the absolute gold standard for body composition. Unlike basic scales, it uses clinical dual-energy X-ray absorptiometry to map your body's exact fat mass, lean muscle distribution, skeletal bone density, and dangerous visceral fat around your organs.

Formula estimations carry a 5% to 10% error margin. A DexaFit DEXA Scan and RMR Metabolism Test measure your exact body fat distribution, visceral fat risk, bone density, and resting metabolic rate in under 5 minutes.
Managing your health and body structure effectively requires looking at both calories (energy) and body composition (fat vs muscle).
Estimates body fat percentage based on biological sex, age, and Body Mass Index (BMI). While it is a quick and zero-effort indicator, it can misclassify high-muscle individuals.
Evaluates the weight-to-height ratio to classify weight health status. Standard medical ranges span Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), and Obesity (30+).
Basal Metabolic Rate is the daily baseline energy your body consumes to maintain organ functions (breathing, temperature, circulation) at absolute rest. We calculate this with Mifflin-St Jeor.
TDEE factors in your BMR plus physical movements (exercise, steps, jobs). This determines the total calories you burn daily. Eating below this creates a deficit for fat loss.
This calculator gives you a fast estimate — but if you're in the Denver metro, you don't have to settle for an estimate. DexaFit Denver is located in downtown Denver at 1143 Auraria Parkway #204, near the Auraria Campus and minutes from LoDo, Capitol Hill, Five Points, and the Highlands. A clinical DEXA scan, VO2 Max test, or RMR metabolic test replaces every number on this page with a real measurement.
We serve clients from across the Front Range — Aurora, Lakewood, Arvada, Westminster, Littleton, Englewood, Centennial, and Boulder — with easy online booking and results reviewed with you on the spot.
