Formula
Monthly Payment = P × [r(1+r)^n] / [(1+r)^n - 1]
Where: P = Principal, r = Monthly Rate, n = Number of Payments
Total Interest = (Monthly Payment × Number of Payments) - Principal
Total Cost = Principal + Total Interest
Example: Comparing 30-Year vs 15-Year Mortgage
Loan Amount: $300,000
Option 1: 4.5% for 30 years
Option 1 Payment: $1,520.06/month
Option 1 Total Interest: $247,220
Option 2: 4.0% for 15 years
Option 2 Payment: $2,219.06/month
Option 2 Total Interest: $99,431
Savings: $147,789 in interest, but $699/month higher payment
About Mortgage Comparison Calculator
The Mortgage Comparison Calculator is an essential tool for homebuyers and homeowners to compare different mortgage options side-by-side. Whether you're comparing different interest rates, loan terms (15-year vs. 30-year), or evaluating refinance options, this calculator helps you understand the financial implications of each choice. By showing monthly payments, total interest costs, and total loan costs for two different mortgage scenarios, this tool enables you to make informed decisions about which mortgage option best fits your financial goals and budget.
Comparing mortgage options is crucial because small differences in interest rates or loan terms can result in significant differences in total interest paid over the life of the loan. For example, a 0.5% difference in interest rate on a $300,000 loan can save or cost tens of thousands of dollars over 30 years. Similarly, choosing a 15-year mortgage instead of a 30-year mortgage can save substantial interest but requires higher monthly payments. This calculator helps you see these trade-offs clearly.
This calculator is particularly useful when: comparing loan offers from different lenders, evaluating whether to choose a 15-year or 30-year mortgage, deciding whether to refinance to a lower rate, comparing fixed-rate vs. adjustable-rate mortgages, or determining if paying points to lower your interest rate is worth it. By providing a clear side-by-side comparison, this tool helps you understand the true cost of each option and make the best decision for your financial situation.

Understanding Mortgage Comparisons
When comparing mortgages, consider both the monthly payment and the total cost over the life of the loan. A lower monthly payment may seem attractive, but it often comes with higher total interest costs if the loan term is longer or the interest rate is higher. Conversely, a higher monthly payment may be worth it if it significantly reduces total interest paid and shortens the loan term.
Key factors to consider when comparing mortgages include: (1) Monthly payment affordability - can you comfortably make the higher payment if one option requires it?, (2) Total interest cost - how much will you pay in interest over the life of the loan?, (3) Loan term - how long do you want to be paying the mortgage?, (4) Interest rate - even small differences can have significant long-term impacts, and (5) Your financial goals - are you prioritizing lower payments now or lower total cost over time?
Real-World Applications
15 vs. 30 Year Comparison: A borrower compares a $300,000 loan: 30 years at 4.5% = $1,520/month ($247,220 interest) vs. 15 years at 4.0% = $2,219/month ($99,431 interest). The 15-year saves $147,789 in interest but requires $699 more per month.
Rate Comparison: Comparing two 30-year loans at different rates: 4.5% vs. 4.0% on $300,000. The lower rate saves $30,000+ in interest over 30 years with only a $90/month payment difference.
Refinance Decision: A homeowner compares their current 6.5% mortgage to a 5.0% refinance option. The calculator shows they'll save $100,000+ in interest and reduce their monthly payment by $300, helping them decide if refinancing is worth the costs.
Important Considerations
- Consider both monthly payment and total interest when comparing options
- Ensure you can afford the higher payment if one option requires it
- Factor in closing costs and fees when comparing refinance options
- Consider how long you plan to stay in the home when comparing terms
- Small interest rate differences can result in significant long-term savings
- Balance your current budget with long-term financial goals
Frequently Asked Questions
What should I compare when looking at mortgages?
Compare monthly payments, total interest paid over the life of the loan, total loan cost, loan term, and interest rate. Consider both short-term affordability (monthly payment) and long-term cost (total interest). Also factor in closing costs, fees, and how long you plan to stay in the home.
Is a 15-year or 30-year mortgage better?
A 15-year mortgage has higher monthly payments but saves significant interest and builds equity faster. A 30-year mortgage has lower monthly payments but costs more in total interest. Choose based on your budget, financial goals, and ability to make higher payments. You can always make extra payments on a 30-year loan to pay it off faster.
How much does a 0.5% interest rate difference matter?
A 0.5% interest rate difference can save or cost tens of thousands of dollars over the life of a loan. For example, on a $300,000 30-year loan, the difference between 4.5% and 4.0% is approximately $30,000 in total interest. Even small rate differences have significant long-term impacts.
Should I choose a lower payment or lower total cost?
This depends on your financial situation and goals. If you need lower monthly payments to fit your budget, choose the option with lower payments. If you can afford higher payments and want to minimize total interest, choose the option with lower total cost. Consider your current income, future income expectations, and financial goals.
How do I compare mortgages with different terms?
Compare both the monthly payment and total interest paid. A shorter term typically has higher monthly payments but lower total interest. Use this calculator to see the exact differences in payments and total costs. Consider whether you can afford the higher payment and how the shorter term aligns with your financial goals.
What other factors should I consider beyond payment and interest?
Consider closing costs, origination fees, prepayment penalties, loan type (fixed vs. adjustable), lender reputation and service, and how long you plan to stay in the home. Also consider your credit score impact, ability to refinance in the future, and whether the loan terms align with your long-term financial goals.
