# Quick Calculation For Determining House Payment

As consumer taking out a mortgage loan, computing a house payment can be a time-consuming process running calculations, let alone qualifying these days. What consumers don’t oftentimes realize, there’s a much easier way to calculate a house payment.

Some terms to become familiar with:

House Payment or rather PITI

Principal-represents principal balance being paid down over the term of an amortizing mortgage such as a 30 year fixed home loan

Interest-refers to the amount of the payment that goes towards interest each month during the loan repayment e.g. 360 months, 180 months, etc.

Taxes-refers to the monthly property taxes built into the house payment, oftentimes deemed an impound or escrow account

Insurance-represents the monthly amount going towards hazard/fire insurance collected by the lender each month

DTI Debt To Income Ratio

Debt To Income-is the amount of total monthly liabilities expressed as a percentage for qualifying against monthly income. (PITI + monthly liabilities) ÷ monthly income.

## Easy Formula For Determining House Payment

For every \$100,000 borrowed it is approximately \$725 per month PITI

Depictions reflect change in house payment..

• Borrowing \$100,000-expect house payment to be approximately \$725/month
• Borrowing \$200,000-expect house payment to be approximately \$1,450/month
• Borrowing \$300,000-expect house payment to be approximately \$2,175/month
• Borrowing \$400,000-expect house payment to be approximately \$2,900/month
• Borrowing \$500,000-expect house payment to be approximately \$3,625/month

As informed borrower, consider most lenders will want the payment to be no more than 45% of the total monthly liabilities including a proposed housing payment. (*Note this does vary from loan program to loan program, but the consensus is up to a 45% debt ratio)

Let’s say a consumer wants to buy a home for \$350,000.

As we know, a house for \$350,000 using half of the \$725 per month in PITI generates a monthly payment of approximately \$2,537.50 per month. Assuming no other monthly payment liabilities, using a 45% debt to income ratio, a consumer would \$5638 per month in income to offset the house payment in ordo qualify for the mortgage.

### How monthly liabilities affect the numbers in determining house payment eligibility

Using the above example, let’s say the month liabilities consist of ; a lease payment for \$300 per month and another\$80 per month in credit cards. Assuming our example income \$5,638 per month, to purchase that \$350,000 home, the monthly income would have to be \$6,482 per month adjusting for monthly liabilities (determined house payment + liabilities) ÷monthly income. Alternatively, reducing the purchase price to \$300,000 is another solution,  in making  the numbers pencil.

*Mortgage Tip: 45% of the total monthly income less monthly liabilities is the maximum house payment a consumer can qualify at, then simply decipher what the monthly payment is relative to amount sought based upon using \$725 per month for every \$100,000.

Other factors to aware of in qualifying for mortgage loan financing…

→Monthly mortgage insurance changes house payment, less than 20% equity (equity same thing as down payment) will typically contain monthly mortgage insurance paid by the borrower for the benefit of the lender

→Down payment/equity positively influences borrowing power

→Meeting lender’s minimum credit score required for financing, 620 is quite common

→Assets/reserves generally, you’ll need at least two months of PITI saved in the bank to meet lender’s reserve guidelines.
