Casio MJ-120D Plus 12-Digit Tax & Check Calculator

The Casio MJ-120D Plus calculator is a practical business and office calculator designed for users who need more than basic arithmetic. With a 12-digit display, 300-step calculation checking and tax calculation function, it is particularly useful for shops, businesses, offices and other environments where calculations need to be performed and reviewed regularly.

The MJ-120D Plus is a mini-desk type check calculator from Casio. Its extra-large display makes figures easier to read, while three-digit comma markers help users distinguish large numbers more easily. The calculator also provides localized number display, allowing users to switch between digit-separator formats.

For business users, the combination of tax calculation, mark-up, memory and calculation-checking functions makes the calculator useful for pricing, totals, percentages and other everyday financial calculations.

Casio MJ-120D Plus Calculator Specifications

These specifications are from Casio’s official MJ-120D Plus product information.

300-Step Check Calculator

One of the standout features of the Casio MJ-120D Plus calculator is its ability to review up to 300 calculation steps.

This feature is useful when performing longer calculations because you can review the entries made during the calculation rather than having to start again from the beginning.

The calculator also provides Auto Review, which allows a calculation to be reviewed by pressing a single button. During review, values and operators can be changed and the calculation can be executed again to produce an updated result.

For shopkeepers, office workers and business users who regularly enter multiple figures, this can make checking calculations more convenient.

Tax Calculation Function

The Casio MJ-120D Plus calculator includes a dedicated tax calculation function, making it useful for business and retail calculations.

A tax function can simplify calculations involving prices and applicable tax rates. Instead of manually performing every stage of a tax calculation, the dedicated function provides a convenient way to calculate tax-related amounts.

This makes the MJ-120D Plus particularly useful for shopkeepers, retailers, sales staff and business owners who regularly work with prices and tax calculations.

Remember that the calculator performs the mathematical calculation based on the tax rate entered by the user. It does not determine which tax rate should legally apply.

12-Digit Extra-Large Display

The calculator features a 12-digit extra-large LCD display designed to make numerical information easier to read.

It also includes function command signs and 3-digit comma markers, helping users identify operations and read larger numbers more easily.

The additional two digits compared with a 10-digit calculator can also be useful when working with larger figures.

For business environments where calculations may involve substantial totals, having a 12-digit display provides useful capacity.

Localized Number Display

The Casio MJ-120D Plus calculator supports localized number display.

Casio describes this feature as one-touch switching between digit-separator formats.

This can make large numerical values easier to read depending on the preferred number format.

For users who regularly work with larger business figures, clear number separation can help reduce confusion when reading displayed totals.

Recheck with Sound Assist

The calculator also features Recheck with Sound Assist.

Casio explains that the recheck function can help confirm errors by sound when checking calculation results. If an incorrect key is pressed during a second calculation used to verify the result, the calculator can provide an audible alert.

This provides another useful tool for users who need to verify calculations carefully.

Mark-Up Function

The Casio MJ-120D Plus calculator includes a mark-up function, which can be useful for business pricing calculations.

Shopkeepers and business owners can use mark-up calculations when working with costs, selling prices and margins.

This makes the calculator more suitable for retail and commercial environments than a basic calculator that only provides standard arithmetic functions.

Grand Total and Independent Memory

The MJ-120D Plus includes both Grand Total (GT) and Independent Memory functions.

Grand Total can be useful when combining the results of multiple calculations, while independent memory provides a separate way to store numerical values during calculations.

These functions are particularly useful when working through several figures or separate calculation sequences.

Solar and Battery Power
