Put a calculator on your website to generate leads

Visitors don't email you because your site looks nice. They email you because you helped them answer a question. A calculator does that 24/7.

Why calculators convert

A landing page asks a visitor to trust you. A calculator gives them something useful first — an answer to a question they came with. That reversal is why interactive tools convert so well.

A freelancer who embeds a project quote calculator isn't just displaying content. They're qualifying leads: visitors who use it are actively thinking about hiring someone.

Which calculator fits your business

Freelancers and agencies: a project quote or hourly rate estimator. Designers: a website cost estimator. Financial advisors: a SIP or loan EMI calculator. Coaches: a pricing or savings tool.

The pattern is the same: pick the question your clients ask most, then put the answer in their hands before they ever contact you.

Embedding is a two-minute job

Every Plainso tool ships with an iframe embed. Copy the snippet, paste it into WordPress, Shopify, Webflow, or plain HTML, and it works. No JavaScript to configure, no API keys.

The tool renders in your site's colours, follows your visitors' theme preference, and keeps working without any maintenance on your side.

The 'Powered by Plainso' flywheel

Each embedded tool carries a small link back to Plainso. Someone clicks it, discovers they can build their own tool, and the loop repeats. Your calculator does double duty: it helps your visitors and it grows the ecosystem that keeps it free.
