Frequently asked questions
How is the monthly payment calculated?
Principal and interest follow the amortization formula M = P·r/(1−(1+r)⁻ⁿ), where P is the loan amount, r the monthly rate and n the number of payments. Tax, insurance, PMI and HOA are added for the total payment (PITI).
What is PMI?
Mortgage insurance (PMI) is often required when the down payment is under 20% of the price. The tool adds it automatically in that case and skips it above 20% down.
