Understanding Home Loan Repayments
Home loans are typically repaid through monthly installments. Each payment consists of two components:
Principal
The original amount borrowed.
Interest
The cost of borrowing money from the lender.
In the early years of a mortgage, a larger portion of each payment goes toward interest. As the loan balance decreases, more of each payment is applied to the principal.
Home Loan Repayment Formula
The calculator uses the standard mortgage amortization formula.
Monthly Payment Formula
Where:
- M = Monthly payment
- P = Loan amount (principal)
- r = Monthly interest rate
- n = Total number of payments

Example Home Loan Calculation
Let's examine a practical example.
Loan Details
| Loan Detail | Value |
|---|---|
| Loan Amount | $300,000 |
| Interest Rate | 5% |
| Loan Term | 30 Years |
Step 1: Calculate Monthly Rate
5% ÷ 12 = 0.4167% monthly
Step 2: Determine Number of Payments
30 × 12 = 360 payments
Step 3: Calculate Monthly Repayment
Monthly payment ≈ $1,610.46
Step 4: Total Repayment
$1,610.46 × 360
= $579,765.60
Step 5: Total Interest
$579,765.60 − $300,000
= $279,765.60
Results Summary
| Result | Amount |
|---|---|
| Monthly Payment | $1,610.46 |
| Total Repayment | $579,765.60 |
| Total Interest | $279,765.60 |
| Number of Payments | 360 |
This example highlights how interest can significantly increase the total cost of a mortgage over time.
How Interest Rates Affect Repayments
Interest rates have a major impact on mortgage affordability.
Consider a $250,000 loan over 30 years:
| Interest Rate | Monthly Payment |
|---|---|
| 3% | $1,054 |
| 4% | $1,194 |
| 5% | $1,342 |
| 6% | $1,499 |
| 7% | $1,663 |
Even a small increase in interest rates can add hundreds of dollars to monthly payments and tens of thousands to total loan costs.
How Loan Term Affects Repayment
The repayment period also plays a crucial role.
For a $300,000 loan at 5%:
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 15 Years | $2,372 | $127,000 |
| 20 Years | $1,980 | $175,000 |
| 30 Years | $1,610 | $280,000 |
Shorter terms result in:
- Higher monthly payments
- Lower total interest
Longer terms result in:
- Lower monthly payments
- Higher overall borrowing costs
