The Casio MJ-120D Plus combines 300-step check & recheck with built-in tax calculation functions — the complete business calculator for offices, shops, and accountants in Nepal.
Key Highlights
🔢 12-Digit Extra Large Display — Wide, high-contrast LCD for clear reading of large business figures
🔁 300 Steps Check & Recheck — Scroll through up to 300 calculation steps to verify every entry
🔊 Audio Recheck Function — Sound-assisted verification reads back entries to eliminate input errors
💰 Tax+ / Tax− Calculation Keys — Dedicated tax addition and deduction keys for instant VAT & tax computing
✅ Check Back & Check Forward — Navigate forward and backward through calculation history with ease
🔄 Auto Review & Correct — Edit individual entries within an ongoing calculation without restarting
🌐 Localized Number Display — Toggle digit separator formats including Indian number style
☀️ Dual Solar + Battery Power — Works reliably in all lighting conditions
The Casio MJ-120D Plus Desktop Calculator is a feature-rich professional desktop calculator that stands apart from the standard JJ and DJ-120D models with one critical addition — dedicated TAX+ and TAX− calculation keys — making it the preferred choice for businesses, retailers, and accountants who regularly compute VAT, service tax, and other tax-inclusive or tax-exclusive amounts as part of their daily workflow.
The TAX+ key instantly adds a pre-programmed tax rate to any displayed value — giving you the tax-inclusive total in a single keystroke. The TAX− key performs the reverse — extracting the pre-tax amount from a tax-inclusive total. The tax rate can be set and stored in memory for your specific Nepal VAT rate (13%) or any other applicable rate, eliminating the need for manual percentage calculations on every transaction.
Combined with the 300 Steps Check & Recheck system, the MJ-120D Plus gives you the rare combination of fast tax calculation and comprehensive verification capability in one device. After completing a complex billing or accounting calculation, you can use the CHECK BACK and CHECK FORWARD keys to scroll through every entry in sequence — reviewing inputs against physical invoices, bills, or ledger entries to confirm accuracy before finalizing.
The Audio Recheck function provides sound-assisted verification — the calculator audibly reads back your entered values as you review them, allowing you to cross-check against source documents by ear without visual back-and-forth scanning. This is particularly valuable during long data entry sessions where eye fatigue increases the risk of missed errors.
Auto Review and Correct lets you step into your calculation history and fix a single wrong digit without clearing and restarting — a significant productivity feature for accountants and bookkeepers working with multi-step billing calculations.
The 12-digit extra large LCD accommodates the full range of numbers encountered in business — from small retail transactions to large inventory totals and payroll figures — all displayed clearly without scrolling or truncation. The localized number display includes the Indian comma format standard in Nepal's business community.
Dual solar and battery power ensures consistent operation regardless of ambient lighting — at a counter, in a stockroom, or at a desk by a window.
For shop owners, VAT-registered businesses, accountants, finance staff, and retailers in Nepal who need fast tax computation alongside rigorous calculation verification — the Casio MJ-120D Plus is the most practical all-in-one business calculator available.
