How inputs and calculated fields work together

Cost Calculator for Contact Form 7 Pro adds calculated fields to Contact Form 7 for estimates, quotes, booking totals, and other formula-based results. Radio buttons, checkboxes, and select fields can supply choices for a calculation. The result can appear in the form as users enter or select values.

Use the extension for service and delivery estimates, hotel reservations, rental car costs, appointment pricing, loan and finance calculations, or general calculators. It also supports date, age, ideal weight, calorie, and BMI calculations.

Build arithmetic and conditional formulas

Formulas can use addition, subtraction, multiplication, and division. Parentheses group parts of an expression. Pro also supports advanced calculations and conditional statements using comparison operators. Conditions can return various results based on a visitor's input, and nested if statements can handle several conditions in one calculation.

Available date and numeric functions

Date-related functions include days, months, years, age, and age2. Rounding and numeric functions include round, round2, floor, floor2, ceil, mod, abs, sqrt, pow, sum, avg, min, and max. Other functions include switch, random, sin, cos, rounddown, wordcount, and rounded_multiple. A custom function option is available when a formula requires a function outside this list.

Format totals for the form's purpose

Add one or more calculated fields and select how the result should appear. Pro includes number and currency formatting for values such as a quote, booking cost, service fee, or loan amount. Formatted prices and totals can also appear in Contact Form 7 submissions. The product information describes the plugin as cross-browser compatible.

Install and configure

Create or edit a Contact Form 7 form, add supported radio, checkbox, select, and other input fields, then configure one or more calculated fields and their formulas. Apply number or currency formatting as needed, test the conditions and totals, and place the completed form on the relevant page.
