Pocket calculator CASIO WM-320MT — 12-digit LCD, battery/solar, CR2032, IP54, rubber housing, profit & tax functions

The Casio WM-320MT Pocket Calculator (Black Yellow) is a compact 12-digit calculator with a single-line extra-large display designed for clear, on-the-go calculations. It supports two-way power (solar + battery) to ensure operation in varying light conditions and includes functions for tax, margin and cost/sell calculations. The device features plastic keys engineered for easy operation and key rollover to buffer inputs during fast typing.

Advantages

The extra large display improves readability of numbers and operation symbols. Two-way power uses solar energy when light is sufficient and battery backup when it is not, extending usable life. Key rollover stores rapid key operations in a buffer so no input is lost during high-speed entry. Dedicated functions for cost/sell/margin and tax calculations simplify common retail and accounting tasks, while the percent key provides quick access to profit and discount computations.

Suitable for

• Retail cashiers and shop use
• Small business accounting and pricing
• On-the-go calculations for students and professionals
• Tax and profit margin calculations

Use the tax keys to calculate price plus tax or price less tax and to determine tax amount. The percent (%) key applies to margin, discounts and ratio operations. The display shows current operation symbols (+, -, ×, ÷) to indicate the active function.

Usage recommendations

Place the calculator in sufficient light to allow solar power to operate and preserve battery life. Avoid exposing the device to excessive moisture or strong impact. For continuous high-speed input, rely on the key rollover feature to retain entries.
