Let visitors find their custom price before they contact you
Visitors select their options from price calculator, see a running total, and arrive at the contact or checkout step already knowing what they want
How it works
Build a price calculator in 4 steps
No formulas to hard-code into a theme, no custom JavaScript. Set up your inputs, write your expression in plain syntax, and publish.
Add input fields
Drag in Number, Dropdown, Range Slider, or Payment fields. Each one becomes a variable you can reference in your formula.
Add a result field
Insert a Number or Single Item field where the calculated total appears. Enable Calculations on this field in its field settings
Write your expression
Click the <> button to insert field references, then combine them with operators like *, +, if(), and round(). A validator shows errors before you save.
Publish and collect
Embed the form anywhere on your site. Totals update instantly as visitors fill in their details. Connect a payment gateway to take payment at submission.
Expression builder
Formulas that go beyond basic math
The Calculations add-on gives you a full expression engine. Write conditional pricing rules, volume discounts, and multi-step formulas using the same operators found in spreadsheet software.
Conditional pricing with if() / elseif() / else()
Apply different rates based on quantity tiers, selected service levels, or any field value the user enters.
Math functions: round(), min(), max(), abs(), sqrt()
Round to the nearest dollar, cap a discount at a maximum value, or compute square footage — all inside a single expression field.
Decimal precision control
Set exactly how many decimal places to display on the result — useful for currency outputs, percentages, and measurement totals.
Payment integration
Charge the calculated amount at submission
Connect Stripe, PayPal, or Razorpay to your calculator form. The Payment Total field picks up the calculated result, so the amount the customer pays matches exactly what they saw on-screen.
Payment Single Item links to the result
Place a Payment Single Item field on the form and point its value to your calculated Number field. The gateway charges that exact total.
Send quote totals in email notifications
Use Smart Tags to pull the calculated value into your admin and user notification emails automatically. The customer always gets a written record of what they were quoted.
Conditional logic hides fields that change the price
Show a delivery address field only when the user selects delivery. Show a rush fee field only when they choose same-day turnaround. The formula re-calculates on every change.
Who uses it
Built for businesses that need pricing to be self-service
Any site where the final price depends on user choices is a candidate. Here are the most common setups.
Freelancers & agencies
Let clients build their own project scope and see an estimated cost before they submit a brief. Reduces back-and-forth on pricing calls.
Common forms
Project quote, retainer estimator, hourly rate calculator
Rentals & bookings
Show rental costs based on selected dates, number of guests, or add-ons like insurance and delivery. Visitors see the total before they commit.
Common forms
Vehicle rental, event space booking, equipment hire
Shipping & delivery
Calculate shipping costs from package weight, dimensions, and destination zone. Combine with payment fields so customers prepay at checkout.
Common forms
Freight estimator, courier booking, order total with shipping
Health & fitness
Embed BMI calculators, calorie estimators, or membership pricing based on number of sessions and duration — no plugin required beyond Everest Forms.
Common forms
BMI calculator, gym membership estimator, diet plan form
Finance & insurance
Create mortgage estimators, loan repayment calculators, or insurance quote forms. Use pow() for compound interest and round() for clean output.
Common forms
Mortgage estimator, loan calculator, premium quote form
Custom product orders
Accept print-on-demand, custom clothing, or configured product orders where the price varies by size, quantity, material, and finishing options.
Common forms
Print order form, embroidery quote, configured product form
Common questions
Questions we get from people setting up their first price calculator form.
Which plan includes the Calculations add-on?
The Calculations add-on is available on the Premium plan. You can activate it from the Everest Forms → Add-ons screen after installing Everest Forms Pro.
Can I build a tiered discount — cheaper per unit as quantity goes up?
Yes. Use if() / elseif() / else() conditional operators in your expression to apply different multipliers at different quantity thresholds. There is no limit to the number of tiers you can define.
Does the total update in real time while the user fills in the form?
Yes. The result field re-evaluates every time a user changes any input that the formula references. No page reload is required.
Can I have more than one calculated field on the same form?
Yes. You can enable calculations on multiple Number and Single Item fields within the same form, and each field can reference different inputs or the same ones in different combinations.
What input fields can I use in a calculation?
Single Line Text, Number, Dropdown, Multiple Choice, Email, Website/URL, Range Slider, Payment Checkboxes, Payment Total, Payment Multiple Choice, and Payment Single Item can all be referenced in expressions.
