Variable	Meaning	Unit	Typical Range
A	Final Balance	Currency ($)	Varies
P	Initial Principal	Currency ($)	$0 – $1,000,000
PMT	Monthly Contribution	Currency ($)	$0 – $10,000
r	Annual Interest Rate	Percentage (%)	0.1% – 15%
n	Compounding Frequency	Times per Year	1, 4, 12, 365
t	Time Horizon	Years	1 – 50
