	BigDecimal months = new BigDecimal("12");
	BigDecimal monthlyRate = rate.divide(months, BigDecimal.ROUND_HALF_DOWN);
	System.out.println("Annual rate : " + rate);
	System.out.println("Monthly rate: " + monthlyRate);
	BigDecimal balance = new BigDecimal("10000.0000");
	for (int i = 0; i < 12; i++) {
	    BigDecimal interest = balance.multiply(monthlyRate);
