## What is Par?

The last calculator you need. Par is a full RPN financial calculator that follows the classic gold-key keystrokes, so the steps you learned years ago, or find in any finance textbook, work exactly as written.

TIME VALUE OF MONEY
• Solve for n, i, PV, PMT or FV, with payments at the beginning or end
• Monthly shortcuts for years and annual rates
• Odd first periods, with simple or compound interest
• Amortization: interest, principal and balance for any range of payments

CASH FLOWS
• NPV and IRR, with repeated flows grouped
• Review and change any flow without re-entering the rest
• A cash-flow diagram drawn as you enter them

BONDS, DEPRECIATION AND DATES
• Bond price, accrued interest and yield to maturity
• Straight-line, sum-of-the-years'-digits and declining-balance depreciation
• Future dates with the weekday, and days between dates (actual and 30/360)

STATISTICS AND MATH
• Mean, standard deviation, weighted mean and linear estimates with correlation
• Percent, percent of total and percent change
• Powers, roots, logarithms, factorials and rounding to the display

PROGRAMMABLE
• Up to 99 program lines with branching, loops, pauses and conditional tests
• Step through programs line by line, and edit them in place

SEE WHAT A CALCULATOR USUALLY HIDES
• The whole stack, shown live above the display
• Financial and storage registers in a side panel, with the program you're writing
• History of every calculation, to revisit and reuse
• Lessons that walk you through real problems, and help for every key

MADE FOR IPHONE AND IPAD
• Portrait and landscape, with a 10 × 4 keypad wherever it fits
• Liquid Glass design that follows light and dark mode
• Skins: Classic, Graphite and Paper, or choose your own colors and share them
• Hardware keyboard and iPad menu bar
• Siri and Shortcuts: loan payments, investment growth, days between dates, NPV, IRR and your last answer
• Apple Watch app with quick solvers, your synced history and a complication showing the latest answer on your watch
• VoiceOver, Voice Control, larger text and Increase Contrast
• Your numbers and programs are kept between launches
• History syncs between your iPhone and iPad with iCloud

Checked against more than 80 worked examples from the classic financial calculator handbook, with 10-digit accuracy and the same rounding.
