A fiftieth birthday dinner is one of those moments where you want everything to be perfect. You are likely looking at a private room to fit everyone, which means you need to lock in your reservation at least three months out. If you wait until a few weeks before, you will be stuck with whatever table is left in the noisy main room.
We can make the math work without a massive hit to your monthly cash flow. If you plan ahead, you can turn a large one-time expense into a series of smaller, manageable payments.
That 18-month window is a deadline, not a gift. If you still have a balance once the 0% period ends, the bank will start charging interest on whatever is left, which can get expensive fast. Pay it off before the time is up.
