Mortgage & real-estate calculators
Estimate the real monthly cost of a home, decide whether to refinance, and compare renting against buying. Each tool shows its assumptions so you can plan with confidence.
A mortgage payment is more than principal and interest — taxes, insurance, and HOA (PITI) often add hundreds a month. Start with the Mortgage Calculator for the full payment and a yearly amortization schedule, then test an extra payment or a refinance (watch the break-even month). Deciding whether to own at all? Compare with Rent vs. Buy and, for investors, Rental ROI.
Common decisions
- What is my true monthly payment? → Mortgage (with PITI + amortization)
- Should I refinance? → Refinance break-even month
- Can I afford this house? → Home Affordability
- Rent or buy? → Rent vs. Buy; Investor? → Rental ROI, BRRRR
