Store description excerpt
The 10bII+ you already know — on the phone that's already in your pocket. Same keys, same shifts, same answers. Ten BII Pro is a complete recreation of the classic 10bII+ financial calculator for iPhone and iPad. Same key layout, same orange and blue shift functions, same entry conventions. Your muscle memory transfers on the first press — there is nothing to relearn. Built for real-estate agents, loan officers, finance students, and exam candidates who learned these keystrokes once and would rather not learn them again. WHY THE ANSWERS ARE RIGHT Every worked example in the calculator's official user manual — all 214 of them — runs as an automated test against this app, keystroke by keystroke, with more than 600 individual results checked against the manual's printed answers. Loans, leases, amortization ranges, bond yield-to-call, declining-balance depreciation, all six regression models, date math. The manual's Table 6-5 says a $930 monthly payment at 7.5% supports a $133,006.39 mortgage. Ten BII Pro says $133,006.39. That isn't a marketing line — it's the test suite the app has to pass before it ships. TIME VALUE OF MONEY • N, I/YR, PV, PMT, FV — solve for any variable • Payments per year, compounding periods, Begin/End mode • Full amortization schedules (AMORT), single period or range • Nominal ↔ effective interest rate conversion CASH FLOWS • NPV, NFV, and IRR/YR on uneven cash-flow streams • CF0 plus 44 cash-flow groups, each with repeat counts • Full cash-flow editor: scroll, jump, insert, delete, running totals BONDS & DATES • Bond price, yield to maturity, yield to call, accrued interest • Actual/actual and 30/360 day counts, annual or semiannual coupons • Date arithmetic and day-count calculations BUSINESS & DEPRECIATION • Cost, price, margin, markup, percent change • Break-even analysis • Straight-line, declining-balance, and sum-of-years-digits depreciation STATISTICS & PROBABILITY • One- and two-variable statistics with a full data editor • Six regression models plus automatic Best Fit • Forecasting, correlation, weighted mean • Permutations, combinations, factorial, z and t distributions THE DETAILS THAT MATTER • Chain and Algebraic modes, parentheses, constant (K) • 20 storage registers with register arithmetic • Adjustable decimal display and US/international separators • Full VoiceOver support — every key announces what it will actually do under the shift that's active • Universal: buy once, use on both iPhone and iPad NO CATCHES One price, paid once. No subscription. No ads. No account. No network access at all — Ten BII Pro can't collect anything about you because it never talks to anything. It works on a plane, in a basement, and at a client's kitchen table with one bar of signal. Ten BII Pro is an independent app and is not affiliated with or endorsed by HP Inc.
