Cost Calculators

Interactive cost calculator on the website: the client calculates the approximate price themselves and leaves a contact.

Who this is for

Construction, renovations, cleaning, transport and manufacturing.

Problem

"How much does it cost?" is the most common unanswered question. It applies to industries where price always depends on scope: construction, renovations, cleaning, transport and manufacturing.

What we do

We build an interactive service pricing calculator embedded on the website.

What's included

Four stages, the last one ties the calculator to the lead workflow:

• Pricing logic
• Interface
• Implementation
• Lead integration

Timeline

Realization takes 6 hours – 2 days. The stages are known: pricing logic, interface, implementation, lead integration.

Cost

The heaviest part is the calculation logic: the rules, the exceptions and the dependencies between them. The look is added on top, but it is usually a smaller part of the job than agreeing how you actually price what you sell.

What you get

Client engagement and a ready warm lead instead of a question about price with no answer.

The formula the pricing calculator runs on

The calculator on the site doesn't guess a price — it computes it according to a rule you set together with us in advance. The general form of the formula looks like this:

• b — the base price: the starting point every quote is calculated from, regardless of scope
• x₁…xₙ — variables the client enters in the form: area, number of rooms, material type, delivery deadline
• c₁…cₙ — the unit price attached to each variable, set by you, not by us
• m — a complexity multiplier, if certain combinations of variables raise the cost more than the sum of their separate prices
• Estimated price = (b + Σ xᵢ × cᵢ) × m

All the values of b, c and m come from your price list and your own experience — the calculator only performs the calculation, it doesn't invent the rates.

What one manually prepared quote actually costs

Before comparing the cost of a calculator with not having one, it's worth calculating what preparing one quote by hand costs today. The formula, with no number from us:

• t — the time a specialist spends on one quote: the call, the site visit, the calculations, in hours
• s — their hourly rate, meaning the cost to the company per hour of work
• u — the number of inquiries that didn't get a timely reply and fell away before the quote was ready

Monthly cost of manual quoting = t × s × (number of quotes) + the value of lost inquiries u. The second component often outweighs the first — an inquiry nobody answered within three days usually goes to a competitor who replied within the hour.

Three ways to price a job — and how they differ

A quote can be given to the client three different ways, and each handles the same question differently: does the client get a number right away.

• A fixed price list — fastest for the client, but doesn't handle services where the price genuinely depends on scope
• An interactive calculator — the client enters the parameters themselves and sees an estimated price immediately, without waiting for anyone's reply
• An individual quote after a conversation — the most accurate, but takes a specialist's time and risks losing a client who doesn't wait for a reply

A calculator doesn't rule out an individual quote — it can be the first step, after which the details that need a conversation get clarified.

What here is automation, and what is just arithmetic

A pricing calculator is entirely rules and arithmetic, not artificial intelligence — we say that plainly, because calling plain multiplication “artificial intelligence” would be dishonest to you and to the client.

• Arithmetic (not AI): multiplying the area by the price per square metre and adding the base rate
• Arithmetic (not AI): a threshold like “above 100 m² we apply a 1.2 multiplier” — that's a plain condition, not a decision made by a model
• A language model (AI) only enters the picture when the client describes their need in free text, and the system has to extract which calculator variables that text describes

Within the pricing calculator itself, that second case is rare — most implementations stop at the first two points, and that's normal, not a shortcut.

When a pricing calculator doesn't pay off

Not every service is suited to automated pricing, and it's better to check that before building a calculator.

• The price depends mainly on factors invisible without a site visit (condition of the wiring, access to the location) — the calculator will give a number that needs correcting on site anyway
• You get fewer than a handful of inquiries a week — the cost of maintaining the pricing logic can exceed the time manual quoting takes today
• The price list changes more often than once a month (e.g. material prices) — then the calculator needs constant updating that someone has to do
• The service has only one variant and one price — a plain price list on the site is enough here, a calculator adds nothing beyond that

What you need to have on your side

The pricing logic has to come from you — we just translate it into an interface.

• Your actual price list, or the rule you use today to calculate a quote verbally or in a spreadsheet
• A list of exceptions that today change the price outside the standard rule (discounts, surcharges, special cases)
• The range the calculator's result should fall within — an estimated price, not a final offer
• One decision-maker who approves the pricing logic before it goes live

How to check after a month whether the calculator paid off

Measure from your own data, not from the impression that “more people seem to be asking about price”.

• The number of completed calculations in the calculator relative to visits to the page with the calculator
• The share of inquiries that came with a calculator result attached, out of all inquiries that month
• The gap between the calculator's price and the price in the final offer — a big gap means the logic needs fixing, not that the calculator doesn't work
• Time from a calculator-based inquiry to sending the offer, compared with an inquiry without one

The most common mistake when building a pricing calculator

The costliest mistake isn't the visual design — it's pricing logic set without the person who prepares quotes by hand every day. A calculator built “from the owner's head” without checking with whoever actually does the work regularly under- or over-prices specific combinations of variables — and the client gets a number nobody later wants to honor.

What the calculator doesn't do: it doesn't replace the final offer, doesn't account for what can't be measured without a site visit, and doesn't guess at exceptions that weren't written into the rule. It gives an estimated price to start the conversation, not to end it.

What you get

• Calculation model and rules for presenting an indicative price
• Responsive calculator interface
• Result storage and integration with a lead form or CRM

When the problem lies elsewhere

If your problem sounds different, neighbouring areas of the same system stand right next to it — AURA connects them to each other rather than selling them separately:

• Admin panels — A dedicated panel for running your company: leads, clients, content and statistics in one place.
• Booking Systems — Online bookings with confirmations and reminders. Client books themselves, calendar keeps itself in check.
• Dashboards — All company numbers on one screen: leads, sales, marketing and finances.
• Email integrations — Emails that send themselves at the right moment: greetings, offers, confirmations and newsletter — from one correctly configured sender.
