Calculators and plain-language guides for every stage of homeownership — from how much house you can afford to reducing interest through biweekly payments and discount points.
Run the numbers on your mortgage — monthly payments, PMI timeline, points breakeven, biweekly savings, refinancing, and more.
Plain-language explanations of mortgage decisions — with real numbers and clear tradeoffs, not general advice.
A mortgage is typically the largest financial commitment most people make. The decisions made at origination — how much to put down, whether to buy points, which loan term to choose, and whether to add PMI avoidance to the plan — have compounding effects over 15–30 years. A $200/month difference in payment from a slightly higher rate costs over $72,000 across a 30-year loan.
The calculators and guides on this page give you the real numbers so you can compare options before signing. Every calculation uses standard mortgage amortization formulas. For complex decisions involving jumbo loans, investment properties, or significant tax implications, consult a mortgage professional or fee-only financial advisor.
