Payments Annuity

I’m doing a report for school, and I can not find this detail in the book. I thought it said its somewhere, but maybe I’m wrong. I know Captain Wentworth started out with no fortune, and that is why Anne originally broke off their engagement. However, he did go on to make a large amount of money in the Navy. I thought the book mentioned it somewhere, but I’m having a hard time finding it there or on the net. Does anyone know the amount?
