BigDecimal offers a string constructor  You ll need to strip all commas from the number  via via an regex or String filteredString inString replaceAll           You then simply call BigDecimal myBigD new BigDecimal filteredString    You can also create a NumberFormat and call setParseBigDecimal true   Then parse  will give you a BigDecimal without worrying about manually formatting
