How It Works

Calorie Surplus Calculator runs a dedicated pure TypeScript formula module for this tool, then formats the output for the calculator page.

  1. 1

    Read fields

    The form reads Maintenance calories, Daily calorie surplus, and Plan length and applies the displayed defaults only when a value is missing.

  2. 2

    Normalize values

    Numeric inputs, dates, select choices, percentages, and minimum limits are normalized before calculation.

  3. 3

    Apply equation

    The primary equation is target calories = maintenance + surplus.

  4. 4

    Build metrics

    The calculator builds result cards for Daily calorie target, Estimated weekly gain, and Projected gain from the formula output.

  5. 5

    Prepare details

    Supporting rows, charts, schedules, or export rows are prepared when they help explain the answer.

  6. 6

    Format results

    Currency, percentages, dates, decimal places, and labels are formatted for readability before display.
