Real Price shows you what things actually cost not what the sticker says. Enter a price and instantly see the real total after tax, tip, and fees. Or work backward paste in what you paid, and it reverse calculates the base price before all the extras. US users get automatic state sales tax lookup. There's also a Worth It? calculator enter any recurring cost (a subscription, a daily coffee) and see what it really adds up to per year, compared to something concrete like a flight or a new laptop.
