St George Loan Repayment Calculator
Understanding Loan Repayment Calculations
The St George Bank repayment calculator uses a standard amortization formula to determine your home loan repayment, car loan repayment, or personal loan repayment. This mathematical model ensures accurate estimates of your monthly obligations and total interest costs over the life of your loan.
Loan Repayment Formula (EMI):
\[ M = P \times \frac{r(1+r)^n}{(1+r)^n - 1} \]
Where \(M\) is the monthly payment, \(P\) is the principal, \(r\) is the monthly interest rate, and \(n\) is the total number of payments
Formula Components Explained
The St George mortgage repayment calculator breaks down the formula into these key variables:
- \(M\) = Monthly repayment amount (EMI - Equated Monthly Installment)
- \(P\) = Principal loan amount (the amount you borrow)
- \(r\) = Monthly interest rate = Annual Interest Rate ÷ 12 ÷ 100
- \(n\) = Total number of monthly payments = Loan Term (years) × 12
Monthly Interest Rate Calculation
To convert the annual interest rate to a monthly rate for the St George home loan repayment calculator:
\[ r = \frac{\text{Annual Interest Rate}}{12 \times 100} \]
Example: If your St George Bank home loan has an annual interest rate of 6.5%:
\[ r = \frac{6.5}{12 \times 100} = \frac{6.5}{1200} = 0.00541667 \]
Detailed Repayment Example
Let's calculate St George mortgage repayments for a typical home loan scenario using the St George Bank mortgage repayment calculator:
Sample Calculation: $500,000 Home Loan
Loan Details:
- Principal (\(P\)) = $500,000
- Annual Interest Rate = 6.5%
- Loan Term = 30 years
- Repayment Frequency = Monthly
Step 1: Calculate Monthly Interest Rate
\[ r = \frac{6.5}{12 \times 100} = 0.00541667 \]
Step 2: Calculate Total Number of Payments
\[ n = 30 \times 12 = 360 \text{ months} \]
Step 3: Apply the Repayment Formula
\[ M = 500{,}000 \times \frac{0.00541667(1+0.00541667)^{360}}{(1+0.00541667)^{360} - 1} \]
\[ M = 500{,}000 \times \frac{0.00541667 \times 7.244}{7.244 - 1} = 500{,}000 \times \frac{0.03924}{6.244} \]
\[ M = 500{,}000 \times 0.006283 = \$3{,}141.50 \]
Result: Monthly repayment = $3,141.50
Total interest paid over 30 years = $630,940
Total amount repaid = $1,130,940
Extra Repayment Benefits
The extra repayment calculator St George feature demonstrates how additional payments can dramatically reduce your loan term and interest costs. Even small extra payments make a significant impact over time.
Extra Repayment Formula
When making extra repayments on your St George Bank loan, the formula adjusts to:
\[ M_{\text{total}} = M_{\text{standard}} + E \]
Where \(E\) is your extra repayment amount. This reduces the principal faster, leading to:
Revised Loan Term Calculation:
\[ n_{\text{new}} = \frac{\log\left(\frac{M_{\text{total}}}{M_{\text{total}} - P \times r}\right)}{\log(1 + r)} \]
Impact of Extra Repayments Example
Extra $500/Month on $500,000 Loan
| Scenario | Standard Repayment | With $500 Extra |
| Monthly Payment | $3,141.50 | $3,641.50 |
| Loan Term | 30 years | 22.5 years |
| Total Interest | $630,940 | $435,203 |
| Savings | $195,737 saved + 7.5 years faster payoff! | |

Repayment Frequency Comparison
The St George repayment calculator allows you to choose different payment frequencies. Each option has distinct advantages:
Monthly vs. Fortnightly vs. Weekly Repayments
Repayment Frequency Conversion Formula
From Monthly to Fortnightly:
\[ \text{Fortnightly Payment} = \frac{\text{Monthly Payment} \times 12}{26} \]
From Monthly to Weekly:
\[ \text{Weekly Payment} = \frac{\text{Monthly Payment} \times 12}{52} \]
Example: $3,000 Monthly Repayment
- Monthly: $3,000 × 12 = $36,000/year
- Fortnightly: $3,000 × 12 ÷ 26 = $1,384.62 (pays $36,000/year)
- Weekly: $3,000 × 12 ÷ 52 = $692.31 (pays $36,000/year)
Accelerated Fortnightly Payments
An accelerated fortnightly payment strategy with the St George Bank loan repayment calculator involves paying half your monthly amount every two weeks:
Accelerated Fortnightly Formula:
\[ \text{Accelerated Fortnightly} = \frac{\text{Monthly Payment}}{2} \]
This results in 26 payments/year = 13 monthly equivalents (1 extra month/year)
Amortization Schedule Breakdown
Understanding how your St George home loan repayment splits between principal and interest over time is crucial for financial planning:
Principal vs. Interest Over Time
In the early years of your loan, most of each payment goes toward interest. The St George mortgage repayment calculator shows this relationship:
Interest Component (Month 1):
\[ I_1 = P \times r \]
Principal Component (Month 1):
\[ P_1 = M - I_1 \]
Remaining Balance (After Month 1):
\[ B_1 = P - P_1 \]
Amortization Example: First Payment
$500,000 loan at 6.5% p.a., Monthly payment = $3,141.50
Month 1 Breakdown:
- Interest: $500,000 × 0.00541667 = $2,708.34
- Principal: $3,141.50 - $2,708.34 = $433.16
- Remaining Balance: $500,000 - $433.16 = $499,566.84
Year 10 (Month 120) Breakdown:
- Remaining Balance: $429,614
- Interest: $429,614 × 0.00541667 = $2,326.99
- Principal: $3,141.50 - $2,326.99 = $814.51
Year 25 (Month 300) Breakdown:
- Remaining Balance: $134,252
- Interest: $134,252 × 0.00541667 = $727.03
- Principal: $3,141.50 - $727.03 = $2,414.47
