HOW IT WORKS
The simplest calculator you'll ever use. Here's why.
ENTER ANY VALUE
Traditional calculators force you to choose a mode first. Do you want to add tax? Remove tax? Calculate backwards?
With 3-Way Calculator, just type. Net. Gross. Tax. Pick one. That's it.
GET ALL THREE INSTANTLY
The moment you type, the other two values appear. No clicking. No switching. No waiting.
Enter $100 as gross with 20% tax → instantly see net of $80 and tax of $20.
ADJUST WITH NUDGES
Need to fine-tune? Use the ▲/▼ nudge buttons to adjust by small amounts.
Unlike other calculators, your anchor stays stable. The numbers adjust around your starting point.
SMART ROUNDING
Our 3WaySmartRound algorithm works with integers to eliminate floating-point errors. No more $99.9999999.
ANCHOR STABILITY
Your starting value stays put. Other calculators recalculate everything when you change anything. We don't.
INTUITIVE DESIGN
No modes to select. No settings to configure. Just type and see results. Simple as that.
VERSATILE USE
VAT, GST, sales tax, commissions, reverse calculations. One calculator handles it all.
