Prepaid math that includes month 12

On Nubank, write the monthly $ price and the prepaid year. Add the documented renew price. If month-12 is missing, 2026-09-09 prepaid is a guess, not cost-benefit.

On Inter, write the monthly $ price and the prepaid year. Add the documented renew price. If month-12 is missing, 2026-09-09 prepaid is a guess, not cost-benefit.

On C6 Bank, write the monthly $ price and the prepaid year. Add the documented renew price. If month-12 is missing, 2026-09-09 prepaid is a guess, not cost-benefit.
