BasisPointCalculator.com grew out of countless “what’s 25 bps in percent again?” moments while comparing rates, fees, and tiny changes that matter. Everyone had different spreadsheets and shortcuts—so I made a clean, fast calculator that makes bps obvious.

The goal is clarity: type a value and instantly convert bps ⇄ percent ⇄ permille ⇄ decimal, or figure out x bps of any amount (helpful for fees/commissions). No clutter, no sign-up walls—just answers you can trust and double-check.

What I care about

• Accuracy first. Conversions and formulas are transparent (e.g., commission = amount × (bps ÷ 10,000)).
• Privacy by default. Inputs are handled client-side; you shouldn’t need an account to do basic math.
• Speed & clarity. Interface stays readable and fast—even on mid-range phones and spotty networks.
• Accessibility. Keyboard-friendly controls, sensible focus states, and readable typography are non-negotiable.

Where this is going

• Rate-change & spread helpers (e.g., “from A% to B% = ? bps”)
• “Dollar value of bps” quick math for amounts (handy for fees)
• Saved scenarios and CSV/PDF export
• Keyboard shortcuts and dark mode
• More finance micro-tools in the same clean style
