Smoking Cost Calculator

The Smoking Cost Calculator is a science-backed health and fitness utility designed to give you a clear, data-driven picture of your body's energy needs, composition metrics, and training benchmarks. Whether you are estimating daily calorie requirements using Total Daily Energy Expenditure, screening your weight classification with Body Mass Index, measuring resting metabolism through Basal Metabolic Rate, splitting calories into precise protein, carb, and fat targets, or benchmarking your strength with a one-rep-max estimate, this tool uses established physiological equations — including Mifflin–St Jeor for BMR, WHO criteria for BMI classification, and the Epley formula for one-rep-max — to produce reliable numbers rather than vague guesses. Activity multipliers range from sedentary through extra active, matching the clinical scales used by registered dietitians and sports nutritionists. Input your age, sex, height, weight, and activity level, and the calculator returns your personalized metric instantly with supporting context about what the number means and how to act on it. You can toggle freely between metric and imperial units and recalculate as often as your weight, training volume, or goals change. The tool serves athletes periodizing nutrition around competition, recreational gym-goers planning a structured cut or bulk, dietitians building client meal plans, medical professionals performing quick resting-energy screenings, runners calibrating pace and fuel strategy, and anyone simply curious about the energy cost of their lifestyle. All computation runs entirely inside your browser — your weight, body-fat estimates, cycle dates, and other personal metrics are never transmitted to or stored on any server. There is no account to create, no subscription fee, no advertising, and no cap on usage.
