Given
Situation: $34,100 at 4% for 3 years

Formula and solutions:

=> 4% = 4% / 100% = 0.04

Since you did not mention if the 4% increase rate is per monthly or yearly. I
will assume it’s the annual interest rate.

=> 34 100 dollars .04 = 1 364 dollar is the annual interest rate

=> 1 364 dollars
3 years = 4 092 dollars is the total interest for 3
years.
