Daily & Budget Calculators

How to pick the right daily tool

Budgeting: The 10/10/80 Rule Calculator divides every paycheck into give 10%, save 10%, live on 80% — the simplest budget framework that forces both saving and generosity before anything else is spent.

Shopping smarter: The Unit Price Calculator compares any two products by per-ounce or per-unit cost so you always buy the better deal regardless of package size or promotional pricing.

At the table: The Tip Calculator handles a single bill or a group split instantly, with per-person rounding to even cents.
