Ok. And just what is your problem? You want us to analyze your code making untenable assumptions? Please get real...

[stultuske]

that isn't even the entire main method.
it's impossible for us to make anything out of this, let alone know what you are looking for.
but, anyway, you have a ')' too much in your

double newBalance = savingsAmount * Math.pow((1+annualInterestRate/12),(numberofMonths*12)-1)/annualInterestRate);

no doubt your compiler already told you this.
