The following formula is a variation of the ”compound interest formula”, compounded yearly:
I = P (1 + r)t−P
I is the interest you earn/owe
P is the amount of money at the beginning (the principal)
r is the interest rate as a decimal
t is the amount of time (in years)
Please note: The ”t” is in the exponent position. That means it’s raising
(1 + r) to the power of ”t”. You can type this in some online calculators by
holding shift and pressing the ”6” key. That should give you this carrot symbol,
ˆ, which means ”exponent”
