The invention provides a payment method for an electric energy meter. The method comprises the following main steps: S2, whether to choose a conventional prepayment mode is judged, if yes, a step S3 is carried out, and if not, a step S7 is carried out; S3, whether to be forward electricity is judged, if yes, a step S5 is carried out; S4, whether to be backward electricity is judged, if yes, the step S5 is carried out; S5, deduction of recharge balance is carried out; S7, whether to choose a preferential deduction mode is judged, and if yes, a step S8 is carried out; S8, whether to be forward electricity is judged, if yes, a step S9 is carried out; S9, whether backward electricity is sufficient is judged, and if yes, a step S10 is carried out; S10, deduction of backward electricity is carried out, and a step S11 is carried out; S14, whether to be backward electricity is judged, if yes, a step S15 is carried out; and S15, backward electricity is accumulated, and a step S16 is carried out. As the preferential deduction mode is set, preferential deduction of backward electricity is carried out when the forward electricity is used, the contribution of the user to the charging of a powergrid can be reasonably rewarded, and the electricity management is more reasonable.
