额度 用英语怎么说？

credit limit

在移动支付场景里，额度常译作 credit limit，指花呗、信用卡等可消费或透支的最高金额。

My credit limit on the mobile payment app is 5,000 yuan, so I can't scan to pay for this item.

我在移动支付应用上的额度是五千元，所以无法扫码支付这件商品。

If you exceed your credit limit, the payment may be declined, but any refund still goes back to your original method.

如果你超出额度，付款可能被拒绝，但退款仍会原路退回。
