Where FormTs Stands Out

Submission-Based Billing

You only pay for actual form completions, not page views. ConvertCalculator's visit-based billing counts every page load — even if the visitor never interacts with the calculator.

PDF Generation Included

Generate branded PDF quotes for free on all plans. ConvertCalculator only offers PDF generation on the Platinum plan at $120/mo.

TypeScript vs Excel Formulas

Write real code with full IDE support, type checking, and unlimited complexity. ConvertCalculator's Excel-like syntax works for spreadsheet users but has limitations for complex logic.

Where ConvertCalculator Stands Out

Familiar Excel-Like Formulas

If your team already thinks in spreadsheets, ConvertCalculator's Excel-style formula syntax (SUM, IF, VLOOKUP) feels immediately familiar. No programming required.

Payment Collection

ConvertCalculator supports Stripe and Mollie payments on Premium+ plans. FormTs does not currently offer built-in payment processing.

WordPress Plugin

ConvertCalculator offers a dedicated WordPress plugin for easy embedding. FormTs uses a universal 2-line embed script that works on any platform including WordPress.

Frequently Asked Questions

Is this comparison fair and accurate?

We aim to be transparent. All ConvertCalculator data on this page comes from publicly available sources: convertcalculator.com/pricing and ConvertCalculator help documentation, accessed in February 2026. If you spot an inaccuracy, please contact us and we'll correct it.

What are 'visits' vs 'submissions'?

A visit (ConvertCalculator's billing unit) counts every time a page with the embedded calculator loads — even if the visitor never interacts with it. A submission (FormTs's billing unit) only counts when someone actually completes and submits the form. High-traffic pages will consume ConvertCalculator visits much faster.

ConvertCalculator uses Excel formulas. Is that easier than TypeScript?

It depends on your background. If you're comfortable with Excel formulas like IF(), SUM(), and VLOOKUP(), ConvertCalculator will feel familiar. TypeScript is more powerful and offers better tooling (autocomplete, error checking), but has a steeper learning curve for non-programmers. FormTs also includes an AI assistant that can write formulas from plain English descriptions.

Why does ConvertCalculator's PDF cost $120/mo?

ConvertCalculator's PDF generation is only available on the Platinum plan ($120/mo). This plan also includes 50,000 visits/month, 25 calculators, and advanced features. FormTs includes PDF generation on all plans, including the free tier.
