function

Safe Formula Engine

Recursive descent parser with no eval() or Function() constructor. Supports arithmetic, comparisons, ternary conditionals, and seven functions: round, floor, ceil, abs, min, max, and if. Output chaining lets later results reference earlier ones.

trending_up

Animated Real-Time Results

Count-up animation with easeOutCubic easing at 60fps using requestAnimationFrame. Numbers animate between previous and new values. Four output formats: number, currency, percent, and decimal. Up to 6 result outputs with a primary highlight card.

link

Shareable URL State

Every input value encodes into the page URL automatically. Visitors share their exact calculator state with one link. Namespaced parameters support multiple calculators on the same page. Copy Results Link button with clipboard integration.

HubSpot Form Integration

Connect any HubSpot form with four trigger modes: on page load, after first interaction, on CTA click, or disabled. Form submission shows a customizable thank you message while the calculator stays functional.

No eval() Security Risk

The formula engine tokenizes expressions and builds an abstract syntax tree without executing arbitrary code. Division by zero is caught. NaN and Infinity are validated. Safe for enterprise and regulated industries.

accessibility

Accessible by Default

Semantic HTML with ARIA labels on all interactive elements. Focus-visible outlines. Tooltip buttons with proper aria-label attributes. Respects prefers-reduced-motion by disabling all animations when the visitor has that setting enabled.

palette

49 Style Controls

24 color fields with opacity, Google Font picker, 7 font sizes, result card radius and padding and shadow, slider thumb and track sizing, container width and padding, hover effects, and a responsive breakpoint. Light, dark, or branded designs without CSS.

What you can build

ROI Calculator Pro works for any interactive calculation. Here are four ways teams use it.

SaaS ROI calculator

Inputs for current tool cost, team size, and hours on manual work. Outputs for annual savings, hours recovered, and payback period. Primary output card highlights the dollar amount. Form gated on CTA click. Sales team sends pre-configured links to prospects.

Hiring cost estimator

Inputs for number of hires, average salary, recruiter fees, and onboarding costs. Outputs for total hiring cost, cost per hire, and time to productivity. Dropdown for department selection adjusts salary ranges. Useful for HR tech and staffing companies.

Insurance savings calculator

Inputs for current premium, coverage type, deductible level, and household size. Outputs for estimated savings, recommended coverage, and annual cost. Toggle for bundled versus individual policies. CTA links to a quote request form.

Pricing configurator

Inputs for user count, storage tier, and support level. Outputs for monthly cost, annual cost, and savings versus monthly billing. Constants for per-user pricing at each tier. Replaces static pricing cards with an interactive tool.

Works with any HubSpot theme

ROI Calculator Pro is a standalone module. Install it in any HubSpot CMS portal and drop it on any page including website pages, landing pages, and blog posts. No theme dependency, no jQuery, no eval(). Pure vanilla JavaScript with FontAwesome icons for result cards.

Questions

Is the formula engine safe for enterprise use?

add

Yes. The engine uses a recursive descent parser that tokenizes and evaluates expressions without eval() or Function(). No arbitrary code execution. Division by zero, NaN, and Infinity are all handled safely.

Can I build multiple calculators on the same page?

add

Yes. Each instance uses namespaced URL parameters and scoped CSS. Three calculators on one page will not interfere with each other. Each has its own inputs, formulas, outputs, and styling.

Does it work with HubSpot forms for lead capture?

add

Yes. Paste any HubSpot form ID and choose from four trigger modes: show on page load, after first interaction, on CTA click, or disabled. The form submits directly to your HubSpot CRM.

Do you offer support?

add

Yes. Documentation included, plus email support for setup and customization questions. Response time is within 5 business days.
