Calorie Calculator

GDPR-ready: Optional privacy consent before storing calculator logs — turn it on under Behaviour, with a customisable consent label.

Calorie Calculator is a free WordPress calorie calculator for fitness, nutrition, health, and coaching sites. Visitors estimate daily calorie needs from age, sex, height, weight, and activity — then see clear BMI, BMR, TDEE, and lose/gain guidelines.

Embed it with a block, shortcode, Elementor widget, or classic sidebar widget. Configure layouts and colours once under Look & feel, then reuse the same calculator across pages.

Results are estimates based on averages. Encourage a balanced diet and sensible activity alongside the numbers.

Why add a calorie calculator?

Interactive tools keep visitors on the page longer and turn curiosity into leads. Optional name and email fields store private Calculator Logs in wp-admin, and Free can notify you or fire a webhook when a log is created.

Science behind the numbers

Free uses the Mifflin–St Jeor equation for basal metabolic rate (BMR), then an activity multiplier for total daily energy expenditure (TDEE / maintain calories). BMI uses height and weight and shows a category label. Results always name the formula used.

What Free results include

• BMI with category (underweight, normal, overweight, or obese)
• BMR — calories at rest
• TDEE — calories to maintain weight for the selected activity level
• Lose / gain calorie targets (for example 0.5 kg / 1 lb per week)
• Goal display as lose/gain lines or a single goal dropdown

How to use

1. Install and activate Calorie Calculator.
2. Add the Calorie Calculator block, shortcode [calorie_calculator], Elementor widget, or classic widget.
3. Units default to both US and Metric; you can show only one.
4. Pick a layout: Modern, Card, Plain HTML (theme-friendly), or Classic — or set a site-wide default under Look & feel.
5. Optionally show Name and Email fields to store calculator logs.

Using shortcodes

• Default: [calorie_calculator]
• In PHP/themes: <?php echo do_shortcode( '[calorie_calculator]' ); ?>
• Useful Free attributes:
  • unit="usunit/metricunit/both" (default both)
  • template="general/bootstrap-general/plain/old" (omit to use the Look & feel default)
  • show_name_field="true/false" (default true)
  • show_email_field="true/false" (default true)
  • show_firstname_only="true/false" (default false)
  • goal_ui="lines/dropdown" (default follows Behaviour, otherwise lines)
• Example: [calorie_calculator unit="metricunit" template="general"]

Tip: open Calorie Calculator → Embed for a shortcode builder with live preview and Copy.

Calculator logs

When name and/or email fields are used, submissions can be stored as private Calculator Logs (including BMI and basal BMR). Open Calorie Calculator → Logs to review them. Logs are not publicly queryable.

Look & feel (Free)

Under Calorie Calculator → Look & feel you can:

• Set the site-wide default layout (Modern, Card, Plain HTML, or Classic)
• Choose a base font size (small / normal / large)
• Set primary and alert / error colours (defaults match the Modern teal + yellow brand)

Behaviour (Free)

Under Calorie Calculator → Behaviour you can:

• Choose the default goal display: lose/gain lines or a single goal dropdown
• Require a GDPR / privacy consent checkbox before a log is stored (customisable label)
• Send an outbound webhook (Zapier / Make / n8n Catch Hook) when a log is created
• Optionally email the admin when a calculator log is stored

Tools (Free)

Under Calorie Calculator → Tools you can:

• Export / import settings (and restore defaults) for migration or support
• Copy a system info report for support threads (no secrets)

Pro locked previews

Settings also show locked Pro tabs (Formula & goals, Labels, Integrations, Email, Foods & exercises) so you can preview upgrades without leaving Free. The calculator itself remains fully usable on Free.

Pro version

Calorie Calculator Pro adds PDF download, email results, email-required lead gate, macronutrient breakdown, mailing-list integrations, foods and exercises tables, body fat / Katch–McArdle, Labels overrides, multi-step form flow, and premium support.
