Best quote calculator software for a service business website
In short
There are three ways to put an instant quote on a website: hire a developer, use a calculator builder where you write the fields and formulas (ConvertCalculator, Calconic, involve.me, Outgrow), or use Brift, which builds the calculator from your website and adds an agent that answers questions about the quote.

Calculator builder or AI agent: the real difference
A builder gives you fields and formulas: you decide the questions, prices and rules, then embed the result. It is flexible, and it is work every time a price changes.
Brift starts from your website: it reads your services and published prices, suggests the questions that drive price in your trade, and shows the range in a conversation. Visitors can also ask follow-ups ("what if the yard slopes?") and get an answer.
Limits to check before you pick
Builders cap visits, impressions, funnels or leads per month depending on the plan. Check the cap against your traffic: a calculator that stops showing in a busy month loses leads when they matter most. Brift has no cap on conversations.

FAQ
Is there a free quote calculator?
ConvertCalculator and Calconic have limited free plans. See each pricing page for the current caps.
Should a quote calculator show a firm price?
Usually not: a range avoids misunderstandings, and the firm quote follows the site visit.
Do I need a developer?
Not for the builders or for Brift. For a fully custom calculator, yes.
