Mortgage Payment Formula Explained
Mortgage payments are calculated using the standard amortization formula.
Mortgage Formula
M=P(1+r)n−1r(1+r)n
Where:
| Symbol | Meaning |
|---|---|
| M | Periodic mortgage payment |
| P | Loan amount |
| r | Interest rate per payment period |
| n | Total number of payments |
Understanding the Formula
The formula determines how much you must pay during each payment period to fully repay the loan and accumulated interest by the end of the mortgage term.
The payment includes:
- Principal repayment
- Interest charges
At the beginning of the loan, a larger portion goes toward interest. Over time, more of the payment applies to the principal balance.
Example Mortgage Calculation
Let’s calculate a typical mortgage payment.
Example:
| Loan Details | Value |
|---|---|
| Loan Amount | $100,000 |
| Interest Rate | 6% |
| Loan Term | 30 Years |
| Payment Frequency | Monthly |
Results:
| Mortgage Result | Amount |
|---|---|
| Monthly Payment | $599.55 |
| Total Payments | $215,838 |
| Total Interest | $115,838 |
This means a borrower pays more in interest than the original amount borrowed over the full 30-year term.
Mortgage Payment Examples by Interest Rate
Here’s how different interest rates affect a $100,000 mortgage over 30 years.
| Interest Rate | Monthly Payment | Total Interest |
|---|---|---|
| 3% | $421.60 | $51,776 |
| 4% | $477.42 | $71,869 |
| 5% | $536.82 | $93,255 |
| 6% | $599.55 | $115,838 |
| 7% | $665.30 | $139,508 |
| 8% | $733.76 | $164,154 |
Even a 1% increase in interest can add thousands of dollars to the total repayment cost.
Monthly vs Bi-Weekly vs Weekly Payments
Payment frequency affects how quickly you repay your mortgage.
Comparison Table
| Frequency | Payments Per Year | Potential Benefit |
|---|---|---|
| Monthly | 12 | Standard repayment |
| Bi-Weekly | 26 | Faster payoff |
| Weekly | 52 | Reduced interest over time |
Bi-weekly and weekly payments can reduce total interest because you make payments more frequently.
Benefits of Bi-Weekly Mortgage Payments
Many homeowners choose bi-weekly payments because they effectively make one extra monthly payment each year.
Advantages:
- Faster loan payoff
- Lower total interest
- Improved budgeting
- Builds equity quicker
Understanding Total Interest
Interest is the lender’s charge for borrowing money. The longer your mortgage term, the more interest you generally pay.
Example Comparison
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 15 Years | Higher | Lower |
| 30 Years | Lower | Higher |
A shorter loan term increases monthly payments but significantly reduces lifetime interest costs.
15-Year vs 30-Year Mortgage
Choosing the right mortgage term depends on your financial goals.
15-Year Mortgage
Pros:
- Lower total interest
- Faster ownership
- Builds equity quickly
Cons:
- Higher monthly payments
30-Year Mortgage
Pros:
- Lower monthly payments
- Easier budgeting
- More flexibility
Cons:
- Higher total interest
