Introduction
This CBA Loan Repayment Calculator shows what a loan will really cost you. Type in your loan amount, term, and interest rate. The calculator shows your weekly, fortnightly, or monthly repayment right away.
It works for personal loans, car loans, and home improvement loans. You can pick a fixed or variable rate. You can also add fees, like an upfront fee or a monthly account fee, to see how much they add to your cost.
You get more than one number. The tool shows your total interest, total fees, comparison rate, and how many repayments you will make. Charts show where each dollar goes and how your balance drops to zero. A full repayment schedule lists every payment, and a step-by-step section shows the math behind the answer.
Want to test two options? Turn on compare mode and check two loans side by side. The calculator tells you which one costs less and by how much. Use it before you apply, so you know what fits your budget. For related tools, try our CBA Repayment Calculator, the Commbank Loan Calculator, or the Commbank Home Loan Calculator for property borrowing.
How to use our CBA Loan Repayment Calculator
Enter your loan amount, term, interest rate and how often you pay. The calculator shows your repayment, total interest, total fees, cost of credit, comparison rate and a full repayment schedule.
Loan purpose: Pick Personal Loan, Car Loan or Home Improvement Loan. This sets the typical rate range shown under the rate box. For a deeper dive on each type, see our Personal Loan Calculator, Auto Loan Calculator and Home Equity Loan Calculator.
Rate type: Choose Fixed if your rate stays the same, or Variable if it can change. Variable adds a note that your real repayments may move. You can test different rates with the Loan Interest Rate Calculator.
Loan amount: Type how much you want to borrow, or drag the slider. You can enter $1,000 up to $100,000. Check what you can safely carry with a DTI Calculator or a Budget Calculator.
Loan term: Choose Years or Months, then type the number or use the slider. The range is 1 to 7 years (12 to 84 months).
Annual interest rate (p.a.): Type your rate, like 6.99%. You can type any rate from 0.01% to 30.00%, and the slider moves in 0.25% steps. To see how interest builds over time, try the Loan Interest Calculator or the Compound Interest Calculator.
Repayment frequency: Pick Weekly, Fortnightly or Monthly. This changes the size and number of your repayments.
Include fees (optional): Click this to add an establishment (upfront) fee and a monthly account-keeping fee. Fees are added to your total cost and lift your comparison rate — the same idea behind our APR Calculator.
Compare a second loan: Turn this on to fill in Loan B and see both loans side by side, with the dollar difference and which one is cheaper. Our Loan Comparison Calculator is another handy way to weigh two offers.
Calculate, Reset and Print: Results update as you type, but you can click Calculate to refresh. Reset puts the default values back, and Print Summary prints your results and schedule.
Loan Repayments Explained
A loan repayment is the set amount you pay back to the bank each week, fortnight, or month. Every repayment is split into two parts: principal (the money you borrowed) and interest (what the bank charges you for lending it). Early on, most of your payment goes to interest. Near the end, most of it goes to principal. This slow shift is called amortisation — you can map it out payment by payment with the Amortization Calculator.
What Changes Your Repayment
- Loan amount: Borrow more and you pay more each time. Use the Loan Payment Calculator to test different sizes.
- Loan term: A longer term lowers each repayment but raises the total interest you pay. A shorter term costs more each month but less overall.
- Interest rate: Even a small rate drop can save you hundreds or thousands of dollars. Our interest rate calculator shows the gap.
- Repayment frequency: Weekly and fortnightly payments chip away at the balance a little faster than monthly ones.
- Fees: An upfront (establishment) fee and a monthly account-keeping fee both add to your real cost.
Fixed vs Variable Rates
A fixed rate stays the same for the whole term, so your repayment never changes. A variable rate can go up or down, which means your repayment can change too. Fixed rates are easier to budget for. Variable rates can save money if rates fall, but they cost more if rates rise. If a rate change is on the table, the Refinance Calculator can show whether switching pays off.
Why the Comparison Rate Matters
The interest rate alone does not show the full cost of a loan. The comparison rate rolls the interest rate and the fees into one number. Two loans can both advertise 6.99% p.a., but the one with big fees will have a higher comparison rate. Always compare loans using this number, not just the headline rate — the Effective Interest Rate Calculator works on the same principle.
Personal, Car, and Home Improvement Loans
Car loans usually have the lowest rates because the car acts as security — the lender can take it back if you stop paying. See what a vehicle deal looks like with the Car Loan Amortization Calculator or the Used Car Loan Calculator. Unsecured personal loans have no security, so rates are higher. Home improvement loans sit in between. Your credit history, income, and the loan size all affect the rate you are actually offered — a quick look at your credit utilization can help before you apply.
Ways to Pay Less Interest
- Pick the shortest term you can comfortably afford.
- Make extra payments when you can — they come straight off the principal. Model this with the Extra Payment Calculator or the Loan Payoff Calculator.
- Switch to weekly or fortnightly repayments if your lender allows it.
- Check for early repayment (break) fees before you pay a loan off ahead of time — see the Early Payoff Calculator.
- If you hold several debts, rolling them together may cut your rate; test it with the Debt Consolidation Calculator or plan an order of attack with the Debt Snowball Calculator.
These figures are estimates to help you plan. Your real repayment will be confirmed by your lender after a credit check.
