StepKcal is a step-based calorie calculator that turns your real daily step count into a personalized Total Daily Energy Expenditure (TDEE), Basal Metabolic Rate (BMR), and calorie target for weight loss. It uses the Mifflin-St Jeor equation, a widely validated formula, combined with your actual step data to eliminate guesswork. Designed for anyone looking to lose weight or optimize their nutrition based on real activity levels, StepKcal provides a shareable report with a single one-time purchase — no subscription or signup needed.

What Makes StepKcal Stand Out

Step-based activity tracking: Instead of vague activity level descriptions (sedentary, active, etc.), StepKcal uses your actual daily step count from your phone or fitness tracker for precise calorie calculations.
Science-backed formulas: Employs the Mifflin-St Jeor equation for BMR and a step-based NEAT (Non-Exercise Activity Thermogenesis) model to estimate calories burned from steps and daily activity.
Personalized weight loss paces: Generates multiple calorie deficit options (e.g., 0.5 kg/week and 0.7 kg/week) based on your BMI and desired weight, with recommendations for safety and sustainability.
Comprehensive report: Includes BMI assessment, calorie breakdown, macronutrient split (protein, carbs, fats), and weekly weight progress projections — all in one downloadable report.
No subscription, no signup: A single $1.99 purchase gives you full access to your personalized plan, with no recurring fees or account creation.

Who Should Use StepKcal

Individuals seeking science-based weight loss: Anyone tired of generic calorie recommendations and wanting a plan tailored to their actual daily movement will benefit from step-specific calculations.
Fitness enthusiasts and casual walkers: Whether you track steps for general health or have a specific goal, StepKcal adapts to your current activity level and provides clear targets.
Budget-conscious dieters: Those who prefer a one-time purchase over expensive meal plans or subscription apps can get a comprehensive calorie and macro breakdown without ongoing costs.

Frequently Asked Questions

What is StepKcal?

StepKcal is a web-based tool that calculates your personalized daily calorie needs for weight loss based on your actual step count, age, gender, height, weight, and desired weight. It uses the Mifflin-St Jeor equation and a step-based activity model to estimate your TDEE and provide tailored calorie and macronutrient targets.

How does StepKcal work?

You input your age, gender, height, weight, desired weight, average daily steps, and walking pace. StepKcal calculates your BMR, adds calories burned from steps and non-step activity (NEAT), and subtracts a safe calorie deficit to produce multiple weight-loss pace options. Results include daily calorie goals, macronutrient splits, and a weekly weight projection chart.

Is StepKcal accurate?

StepKcal uses the clinically validated Mifflin-St Jeor equation for BMR and estimates activity energy expenditure based on step count and pace, which is a more objective method than self-reported activity levels. While individual metabolism varies, the tool provides a reliable starting point for calorie planning. For personalized medical advice, consult a healthcare professional.
