Calculating accrued interest

[Met Fan]

I want to calculate interest on an old account. If the principle is $3300, account is 68 months old and interest accrues at 1.5% monthly would this be the correct formula to give me the total due including principle and interest:

$3300(1+0.15)^68

Hi,

(1.5% = 0.015 not 0.15)

3300*(1+0.015)^68 or FV(0.015,68,0,-3300) assuming payment accrued in the end of the month
