How the Calculator Works
It uses the standard amortization formula: M = P × r(1+r)n / ((1+r)n – 1), where P is the principal, r is the monthly interest rate, and n is the number of monthly payments.
FAQ
Does it include taxes and insurance?
No — this is principal and interest only. Your actual mortgage payment may include escrow for taxes and insurance.
Is the rate APR or note rate?
Use the note rate (interest rate). APR includes fees and is slightly higher.
Can I use it for car loans?
Yes — works for any fixed-rate amortizing loan: auto, mortgage, personal, student.
Does it support extra payments?
Not yet. This calculator shows the standard scheduled payment.
Is my data saved?
