Never spend on a card holding a transferred balance, since many issuers apply payments to cheaper balances first. Calendar the promo end date with three reminders. If a fee exceeds savings, walk away. Simplicity wins, and clarity about timelines prevents surprise interest spikes that erase months of diligent work.
Rewards rarely beat double-digit APRs. If you carry a balance, treat points as a distraction. Use a single, low-rate card for necessary purchases and pay in full monthly. Once debt is gone, optimize rewards intentionally. Until then, channel every ounce of focus toward principal reduction and interest minimization.
Time autopays for the day after paydays and maintain a small checking cushion. Turn on low-balance alerts. If cash flow is tight, split the extra payment into two smaller, scheduled contributions. These small adjustments protect your banking reputation and keep momentum strong without expensive, embarrassing overdraft hiccups.
