## What is an instant quote calculator?

A quote calculator is a tool on your website that turns a customer’s choices into a price there and then, using your own pricing rules. It’s for trades and product businesses that quote the same kinds of job again and again, and a simple calculator starts from £500.

## Two calculators, and what they produced

For Castia Marble, the instant-quote calculator produced £6,559,011 in worktop quotes from November 2025 to September 2026, tracked in Google Ads. That’s quote value, not sales: a quote only counts when a customer has priced a job and left their details.

For frameless-showers.co.uk, the shower designer and instant quote produced £160,000 in shower quotes from the spring 2026 launch to September 2026, tracked in Google Ads. That’s quote value, not sales.

## What you get

A calculator built around the way you already price.

- A calculator on your own website, built around your products and pricing rules.

- An instant price for the customer, and their details for you when they ask for the quote.

- Rules for the awkward parts, such as sizes, options and the clearances a product needs.

- Hosting, software and fixes while the monthly running cost is in place, at about £50 a month.

## How it works

A simple calculator typically goes live from one week, depending on complexity.

### Tell us how you price

The choices a customer makes, the rules behind your prices and what you need to know before you quote.

### We build it into your website

It sits on the site you already have, as Castia’s does at castiamarble.co.uk/quote, so customers price the job without leaving it.

### Customers price their own jobs

They get a price there and then, and you get their details with the job they priced.

## Questions before you start

### How much does it cost?

A simple calculator starts from £500, plus about £50 a month to run. A calculator with more options and rules costs more.

### How long does it take to go live?

From one week, depending on complexity.

### Do I own it?

Yes. You own everything we build, including the accounts and the data.

### Can I change it myself?

Mostly, yes. We set things up so that most clients can make changes themselves, and we show you how it works.

### What happens if it breaks?

While the monthly running cost is in place, we fix it. Without it, you can pay for a one-off fix. The monthly cost covers hosting, software and fixes, normally with a six-month minimum term.
