Car Loan Calculator
Most car loan calculators are built to help lenders sell you the biggest loan you'll say yes to. This one is built for you. Enter the loan amount, rate and term, and we'll show you what the repayments really look like in your budget, including how much interest you're handing over if you stretch things too far.
Who it's for
- Drivers comparing new or used car finance and wanting to sanity-check the repayments before signing anything.
- Borrowers sense-checking a dealer quote or bank offer against what their budget can handle.
- Anyone reviewing an existing car loan and wondering if the repayments (and interest bill) still make sense.
What it calculates
- Estimated weekly, fortnightly and monthly repayments for a given loan amount, rate and term.
- Total amount repaid over the life of the loan and total interest cost.
- The impact of changing the loan amount, rate or term on your ongoing repayments and long-term cost.
Why it matters
Knowing your repayments upfront stops you sleepwalking into a deal that only looked cheap at the dealership. It lets you compare offers on more than just the headline rate and helps you spot "low repayment" structures that quietly blow out your total interest.

How this Car Loan Calculator works
The LoanGorilla car loan calculator uses the same core formula lenders use to estimate repayments on a principal and interest car loan. You enter how much you want to borrow, the interest rate, the term and how often you'd like to make repayments. Behind the scenes, the calculator converts your annual rate into a weekly, fortnightly or monthly rate, spreads your loan amount over the number of periods in your chosen term, and calculates the repayment required to clear the balance (and any balloon) by the end. It then sums up how much you'd repay in total and how much of that is interest, so you can see the full cost of the deal, not just the slice that comes out of your account each pay cycle.
How to interpret your results
When the results load, focus on:
- Repayment per period – This is what will leave your account every week, fortnight or month. Ask whether it fits your real-world budget once you include rent/mortgage, food, kids, insurance and everything else, not just in theory.
- Total repaid – This is the all-in price of the loan over the full term. It's your best tool for comparing a short, sharp loan against a long, "easy" one.
- Total interest – This is what you're paying purely for access to the money. If that number makes your eyes widen, you've just spotted the cost of stretching too far on either rate or term. If the deal only looks acceptable when you ignore total interest, it probably isn't a deal you should be excited about.
How to find repayments that fit your budget
- Start with your surplus, not your salary – Work out what's left after essentials and savings, and target a repayment that sits comfortably below that surplus.
- Play with the loan amount – Drop the amount in $1,000–$5,000 steps and watch the repayment and interest fall. Often, a slightly cheaper car makes a big difference to stress levels.
- Test different terms – Shorter term = higher repayment, lower total interest. Longer term = lower repayment, higher total interest. Use the slider to find the shortest term you can reasonably manage without starving the rest of your life.
- Be honest about balloons – A balloon can tidy up the monthly figure but leaves a lump sum to deal with later. Only use it if you have a clear plan (like savings or expected resale value) to cover that final hit.
Once you find a combination of amount, rate and term that gives you a repayment you'd be comfortable paying on a bad month, you're in the right zone.
Calculator assumptions
This tool is a general guide only. It uses the loan amount, rate, term and repayment frequency you enter to estimate repayments and total costs, but it doesn't include all lender fees, charges, government taxes or product features. Actual offers will depend on your credit history, income, expenses, the car you choose and each lender's criteria. The results are not a quote, pre-approval or personal advice, use them as a starting point, then compare real products or speak with an adviser before you decide.
