P = principal, r = periodic interest rate, n = number of payments.

Factors Affecting Mortgage Calculator Results

Loan Amount

The sum of all of your borrowings makes a direct contribution to the monthly payment of your borrowing package. Generally, larger borrowings amount for higher payments as well as additional cost in total you'll pay for.

Interest Rate

Any adjustment to your mortgage interest rate (even a very small adjustment) has both a material affect on your monthly payment as well as the cost of obtaining the loan over its duration.

Loan Term

If You Take Your Payment Options to Long, You Will Save More Than I! While you should always compare options carefully in any financial arrangement, here is a general rule for taking either loans out over a longer period: Short Loan Payment periods = higher minimum required payment but ultimately less interest and costs paid. Long Loan Payment periods = lower minimum payments required but a great deal more interest and expenses in the long run

Down Payment

When you put down a bigger portion upfront, there's less balance in the home loan you take on. This has the effect of trimming your monthly payments, and can get you off the hook for extra insurance on your home mortgage.

Property Taxes

The rate of property taxes in your area is important because much of it will be part of calculation if estimated in your monthly mortgage, which most of lenders carry out.

Homeowners Insurance

You're probably used to having insurance payments added to escrow payments which could significantly affect what your total monthly payment really adds up to.

Private Mortgage Insurance (PMI)

PMI - Personal Mortgage Insurance PMI can apply to mortgage loans if down payments are under minimum limits specified by lenders. This can lead to increased housing costs for borrowers.
