Choose how much you want to pay per month

With the deferred revolving payment, pay your purchases in installments, paying a fixed amount of what you have spent with your card each month.

How can I do it?

Go to the App or to bbva.es and select your card.
Select "transactions" if doing so via the website, or "show more" if using the app.
Select "Change payment method".
And choose the amount or percentage you want to pay each month.
