Reading the total interest percentage on a mortgage estimate
Understand the Total Interest Percentage (TIP) on your Loan Estimate to accurately assess the long-term cost of your mortgage loan beyond just the rate.
The short answer
The Total Interest Percentage (TIP) tells you how much total interest you will pay over the entire loan term, expressed as a percentage of the loan amount. It is a powerful tool to measure the cost of borrowing. A lower TIP generally indicates that you are paying less in interest over the life of the loan.
Calculating the Value of TIP
TIP is different from your interest rate. While the rate is a yearly percentage, TIP shows the total interest cost as a ratio of your total loan amount. It helps you understand the 'price' of borrowing the money.
Illustrative Planning Example: If your loan is $200,000 and your TIP is 50%, you will pay $100,000 in interest over the life of the loan. Knowing this figure helps you see the total cost of the mortgage in absolute dollars.
Comparing Loans with TIP
When you receive multiple Loan Estimates, the TIP is an essential metric for comparison. It accounts for the term of the loan and the interest rate, providing a clearer picture of the total interest burden.
Worksheet: For each loan offer, multiply the loan amount by the TIP percentage. Compare the resulting dollar amounts to see which loan is more cost-effective over its full lifespan.
Considering Loan Terms
Loans with shorter terms typically have lower TIP values because you have fewer years to accrue interest. However, this may result in higher monthly payments. Balancing the TIP with your monthly budget is a key part of your home-buying decision.
Ensure you are comparing loans with identical terms (e.g., both 30-year fixed) to get an accurate, 'apples-to-apples' assessment of the TIP.
Professional Inquiry
Use the TIP as a conversation starter with your lender. Understanding why one loan might have a higher TIP than another can reveal hidden costs or differences in loan structure.
Ask: How does my chosen loan term affect the TIP? Are there ways to lower this total interest burden while keeping my monthly payments comfortable?
Checklist
- Find the TIP percentage on your Loan Estimate.
- Calculate the total interest cost in dollars using the loan amount.
- Compare the TIP between two different lenders.
- Verify that your loan terms are identical for the comparison.
- Discuss your long-term interest goals with your loan officer.
Common questions
Is a lower TIP always better?
Generally, a lower TIP means you pay less interest over the life of your loan. However, it is important to balance this with your monthly payment capability. A loan with a lower TIP might have a higher monthly payment that is not sustainable for your budget.
Does TIP include my closing costs?
No, TIP focuses specifically on the total interest paid over the life of the loan as a percentage of the loan amount. It does not include closing costs, origination fees, or other upfront expenses.
