Baseball ERA Calculator

This calculator requires the use of Javascript enabled and capable browsers. This calculator is designed to give the ERA (earned run average) of data entered. The formula is listed below but you may also visit our Baseball Pitching Stats Formulae page. Enter the data that you have in the required data section. Then click on Calculate. You may change a field and re-calculate with other values remaining the same. You may also click on Clear Values and reset all fields and results to initial value defaults. Then click on Calculate. You do NOT have to erase a default value in each field; the system will do it for you but ONLY defaults. All of the fields are set to default to zero (0) if not edited. All of the result fields are for calculated answers only and ARE NOT editable. All fields require NUMERIC entry only! Please see our defensive stats calculator, our pitching stats calculator or our pitching and defensive stats combined calculator.
