Frequently Asked Questions

Everything you need to know about mortgage calculations

How does MortgageIQ calculate monthly payments?

We use the standard amortization formula: M = P[r(1+r)^n]/[(1+r)^n-1], where M is the monthly payment, P is the principal (loan amount), r is the monthly interest rate (annual rate / 12 / 100), and n is the total number of payments (years × 12). This is the same formula used by banks and financial institutions worldwide.

Does the calculation include taxes and insurance?

No, our calculations show only principal and interest (P&I). Your actual monthly payment may be higher if it includes property taxes, homeowners insurance, PMI (Private Mortgage Insurance), or HOA fees. Contact your lender for a complete payment estimate including all these factors.

Is MortgageIQ safe to use?

Absolutely. All calculations are performed locally in your web browser using JavaScript. We don't send any data to external servers, don't collect personal information, and don't use tracking cookies. Your privacy is our priority.

What currencies are supported?

MortgageIQ supports 12+ major currencies including: US Dollar (USD), Euro (EUR), British Pound (GBP), Canadian Dollar (CAD), Australian Dollar (AUD), Japanese Yen (JPY), Swiss Franc (CHF), Mexican Peso (MXN), Brazilian Real (BRL), Colombian Peso (COP), Argentine Peso (ARS), and Chilean Peso (CLP).

How much down payment should I make?

Traditionally, 20% down payment is recommended to avoid PMI (Private Mortgage Insurance). However, many programs allow 3-10% down. A larger down payment reduces your monthly payment and total interest paid over the life of the loan. Use our calculator to compare different scenarios.

Can I see a detailed amortization schedule?

Yes! After calculating your mortgage, click "Show Full Schedule" to see a detailed month-by-month breakdown of your payments, including how much goes to principal vs interest, and your remaining balance for each month of your loan.
