Finance Vs Save Calculator

'Buy now, pay later' — store financing, BNPL apps, the credit-card swipe — all sell the same illusion: that a big purchase is really just a small monthly payment. But that monthly payment is a force, and financing points it the wrong way. When you borrow, every payment carries interest you hand to the lender; when you save up the same amount first, that money earns interest for you, and a cash buyer often gets a discount the financed buyer forfeits. This lesson races the two paths for the exact same item on the exact same monthly budget — the payment you'd owe the lender, pointed at a savings account instead. Scored as net worth, the patient saver always finishes ahead, because the interest that worked against the borrower works for the saver, and the discount lands on top. The only thing financing actually buys you is the item sooner — and the simulator puts a precise dollar price on that head start, so you can judge whether getting it now is worth what it costs. There's one honest exception, and the sim shows it too: a genuine 0% promotion with no cash discount costs almost nothing, because the only thing you give up is the small interest your money would have earned. Outside that case, the rule is simple — if the rate to borrow is higher than the rate to save (it almost always is), save up first.
