Cash Advance Trap

Your cash advance balance could be growing while you make payments

Cash advances from ATMs, Venmo, and crypto purchases carry separate terms most people miss:

  • 29.99%+ APR, separate from your purchase rate, often buried in fine print
  • No grace period. Interest accrues from day one, not your statement date
  • Hidden balance. Your bank shows one total, not the split

Senaro™ models purchase and cash advance balances separately, so you see the real cost.

Example: $2,000 Cash Advance

At 29.99% APR with no grace period, you'd pay $600+ in interest on top, even while making minimum payments on your purchase balance.
