PVIF - Present Value Interest Factor: The current worth of $1 to be received in the future

FVIF - Future Value Interest Factor: The future worth of $1 invested today

PVIFA - Present Value Interest Factor of Annuity: The current worth of $1 received annually

FVIFA - Future Value Interest Factor of Annuity: The future worth of $1 invested annually
