The Cash Drawer Calculator is a free, real-time tool that helps retail workers, small-business owners, and anyone managing cash registers count down drawers instantly.
How It Works (All Automatic):
Input Screen: Enter banknote counts, loose coins, and coin-roll totals. The total cash updates as you type – no “Calculate” button needed.
Target State: Set a drawer target (default $100). The app instantly shows if you’re above, below, or at target.
Drawer Checkout: Tap “Drawer Checkout” to see exactly what to remove (or add) to hit the target. Toggle “Include Coin Rolls” to include/exclude rolls.
Summary Dashboard: View every drawer’s total, target, and status in a single table.
Multiple Drawers:
Guest: Up to 3 drawers (local storage only).
User / Supporter: Up to 10 drawers, synced across devices.
Auto-Save:
Guests: data is saved locally in your browser.
Logged-in users: data is saved to the cloud (Firebase) automatically after every change.
Extra Perks for Logged-In Accounts:
Dark mode (User & Supporter).
Cloud backup – your drawers survive logouts, device changes, or browser clears.
Supporter tier removes ads and unlocks the full 10-drawer limit.
Why It Was Created:
This tool eliminates the tedious, error-prone process of manual cash-counting. It’s fast, mobile-friendly, and works offline for guests. Whether you’re closing a shift, balancing a register, or preparing a deposit, the calculator does the math in real time.
