Create a free business account, choose your calculators, match them to your brand and copy one embed snippet into your site. It works as an inline calculator, a popup or a floating button, on plain HTML pages and on common website builders. Leads from an optional contact form go to a built-in CRM, with an email alert for each one.
Set your colors and choose from several themes so the calculators look like part of your site, not a bolt-on.
Place a calculator inline on a page, open it in a popup from a button, or keep it one tap away with a floating button. One snippet covers each.
An optional form lets visitors send you their details along with their calculator inputs and results. Leads land in a built-in CRM you can work from.
Pick from loans, auto, credit and debt, savings, personal finance and every other category the app offers. Your account limits set how many you run at once.
The business account costs nothing. There is no card to enter: create the account, choose your calculators and start embedding.
Calculator text is fully translated into English, Spanish (Español), Simplified Chinese (简体中文), Korean (한국어), Vietnamese (Tiếng Việt) and Arabic (العربية), with Arabic shown right to left. Visitors can switch language inside the calculator.

Business account
There is one business account, and it is free. It covers a set number of embedded calculators from any category, a multi-calculator widget, a monthly view allowance, a lead contact allowance and one team seat.
The card below shows the current limits. The business account is separate from the consumer site, which stays free for everyone.
Put our calculators on your own site, at no cost.
$0 forever · no card, no checkout

Live example
This is the same car loan calculator our readers use, styled to this site’s palette. On your site it takes your colours and fonts, with an optional lead form that sends visitors' details to your CRM.

Businesses put the calculators on their own sites. They never get influence over what our consumer pages say.
Yes. The consumer site stays free for everyone, and business accounts do not change that. Businesses that embed our calculators have no say over our consumer content, guides or calculator results. Our editorial policy sets out how that separation works.
You do. Leads collected through calculators on your website belong to your business. They appear in your built-in CRM, and you can get an email notification for each one. We do not sell or share your leads with other businesses or use them to market to your visitors.
Usually not. If you can paste HTML into a page, you can embed a calculator. Our embed guide walks through plain HTML pages and common website builders such as WordPress, Wix, Squarespace, Webflow, Shopify and HighLevel. A developer helps only if your site blocks embedded content by policy.
Yes. You can set brand colors and choose a theme so the calculators look like part of your site. The calculators adjust to the width of the space you place them in, including on phones.
They use the same tested formulas as our consumer site, with each worked example recomputed independently. They still produce estimates, so we recommend keeping the built-in disclaimer visible and pointing customers to your official disclosures for final terms. Our methodology page explains the formulas, rounding and testing in detail.
Six: English, Spanish (Español), Simplified Chinese (简体中文), Korean (한국어), Vietnamese (Tiếng Việt) and Arabic (العربية). Every calculator has a language switcher built in, so visitors can change language themselves, and Arabic displays right to left. You can also set the starting language for each embed, so different pages of your site can open in different languages. Any text you write around the calculator on your own page is yours to translate.
Not automatically. Lead webhooks are not part of the free business account, so every lead is stored in the built-in CRM and you get an email notification for each one. You can follow up from there or forward the alert to the tool your team uses. The account card on this page shows the current limits.
No. The business account offered here is free. There is no checkout and no card to enter when you sign up, and the account card on this page shows the current limits. If you have questions before you start, email the partners address and we will answer in plain English.
The calculator processes inputs to show results. If a visitor chooses to submit the lead form, their details and results go to your account so you can follow up. You are responsible for telling your visitors how you use that information in your own privacy policy.
