PPMT is an acronym with multiple uses in finance and project management, and its meaning depends on the context in which it appears.

In finance and spreadsheet software, PPMT refers to a financial function that calculates the principal portion of a loan payment for a given period. It is available in programs like Microsoft Excel and Google Sheets as PPMT(rate, per, nper, pv, [fv], [type]). The function returns the amount of the payment that goes toward reducing the loan principal in the specified period. It is related to other functions such as PMT, which returns the total payment, and IPMT, which returns the interest portion. The parameters include rate (interest rate per period), per (period for which to determine the principal), nper (total number of payment periods), pv (present value or loan amount, typically negative in cash-flow notation), and optional fv (future value) and type (timing of payments). A typical use is in constructing amortization schedules to analyze how much of each payment reduces principal over time. For example, PPMT(0.05/12, 1, 360, -100000) would yield the principal portion of the first payment on a $100,000 loan at 5% annual interest.

In corporate and project management contexts, PPMT can stand for Project Portfolio Management Team, a group responsible for selecting, prioritizing, and overseeing a portfolio of projects to align with strategic objectives. The PPMT coordinates governance, resource allocation, risk management, and performance monitoring, often interacting with a PMO, executives, and business units. The aim is to optimize value delivery across the portfolio by balancing risk, cost, and expected benefits.

Context determines the exact meaning of PPMT, with finance and project management being the most common domains.
