What I changed after building small-business calculator pages

Short summary

A developer shares lessons from building small-business calculator pages, finding that trust and clarity matter more than math. Key changes include inline input notes, showing intermediate results, using honest hedging language, and adding realistic defaults. Each calculator should stay focused on one job rather than trying to handle too many related cases.

• •Inline notes near inputs reduce bad data entry
• •Showing intermediate numbers builds user trust in results
• •Honest hedging language ('estimated', 'rough') beats false precision
• •Keep each calculator focused on one job
