Is there a código descuento B100?
No. B100 is a bank brand, so it has no discount code. What it publishes are account rates and fee terms, quoted here exactly as shown on b100.es on 6 November 2026. This is not financial advice: read the bank's own documents before you open an account.
Current B100 accounts and rates
The B100 current account pays 0% TIN and 0% TAE and has no maintenance or administration fees. The Cuenta Save pays 2,717% TIN and 2,75% TAE on up to 100.000 € to new customers who have not held a B100 account in the last 12 months; the promotion and its rate run until 31 December 2026. B100's example is 5.000 € for one year earning 135,88 € gross. The rate after that date is not stated.
The Cuenta Health pays up to 3,15% TAE on up to 50.000 €, with monthly interest. For 5.000 € the example is 3,106% TIN and 3,15% TAE (155,28 € gross a year) with the card bonus, which needs at least 8 purchases with B100 cards totalling 200 € or more in the previous month, or 2,570% TIN and 2,60% TAE (128,47 € gross) without it.
The Pay to Save debit card
The Visa debit card has no issue or maintenance fees and no foreign currency fee abroad. Customers under 35 get five ATM withdrawals a month outside Spain with no B100 fee, though the ATM network may charge. B100 says it gives 25% of its income from each purchase to collecting plastic from the sea.
Good to know
B100 belongs to ABANCA, which is a member of the Spanish Deposit Guarantee Fund (up to 100.000 € per depositor and bank). Opening an account needs a DNI or TIE and a selfie, plus the modelo 130 if you are self-employed.
