No external services. No monthly fees. No API keys. Everything runs client-side.
How to customize your calculator:
Each input has a Variable Name (like monthlySpend or teamSize). These names are what you use in the formula field. The formula is simple math using those names.
Examples:
monthlySpend * 12 (annual cost)
teamSize * hourlyRate * 2080 (annual labor cost)
monthlySpend * (savingsPercent / 100) * years * 12 (projected savings over time)
revenue > 1000000 ? revenue * 0.05 : revenue * 0.08 (conditional rate)
Available math helpers you can use in formulas: round(), ceil(), floor(), min(), max(), abs()
Quick setup steps:
Drag the component onto your page
In the property panel, open Calculator Inputs
For each input, set a Variable Name, Label, Min, Max, and Default Value
Add a Unit Prefix (like $) or Unit Suffix (like % or hrs) if needed
Write your formula using the variable names
Pick your number format (currency, decimal, percent, or compact)
Set your currency code if using currency format (USD, EUR, GBP, etc.)
Adjust colors to match your brand
Variable names should be letters only with no spaces. Use camelCase for multi-word names (like monthlySpend or hoursPerWeek). If a formula has an error, the result will show $0 instead of breaking.
