How accurate are the numbers?

Every formula uses industry-standard methods — the same amortization math your lender uses. Where we show a benchmark rate it comes from the Federal Reserve (FRED): a national average, labeled with its as-of date and updated weekly or quarterly. It is a benchmark, never a live quote — the rate you can actually get should beat it, and any figure you enter yourself always overrides it. Your data and input is part of the equations, so take care with the estimates you use, and adjust to your best estimates.
