Quando usar um Calculator
You want to give readers a personal number
A savings estimate, a carbon footprint, a risk score. People engage with a result worked out from their own answers.
The answer depends on several inputs
Multiple questions feed one formula, with weights you control, rather than a single lookup.
You want a guided flow
Showing one question at a time keeps each step simple on a phone and lets visitors move back and forth.
You want to collect the answers too
An optional integration sends each submission and its result to a web address you provide.
