How the car affordability calculator works
Start with a total monthly car budget, subtract running costs, then estimate the vehicle price that fits the remaining loan payment.
Payment budget = total monthly budget − monthly running costs. Loan capacity = payment × (1 − (1 + r)^−n) ÷ r; at 0%, payment × n. Tax, fees, down payment and trade assumptions then determine purchase-price capacity.
Read our calculation methodology and limitations.
Turn a payment limit into a durable car budget
Affordability should leave room for ownership costs and financial surprises, not merely satisfy a lender’s maximum.
Reserve ownership costs
Insurance, fuel, maintenance, parking, and registration compete with the loan payment every month. Model them before setting the vehicle-price ceiling.
Treat trade equity carefully
Positive equity can reduce borrowing; negative equity consumes buying power. Verify both the trade offer and payoff amount on the same date.
Keep a cash buffer
Do not automatically commit every available dollar to the down payment. Preserve the emergency reserve your household needs after delivery.
Example
An $800 monthly budget with $300 reserved for insurance, fuel and upkeep leaves $500 for the loan. At 0% for 60 months that supports $30,000 financed—not necessarily a $30,000 sticker price after taxes, fees and down payment.
What affects the result
- Include insurance, fuel and maintenance before assigning the remainder to financing.
- A longer term raises borrowing capacity but can raise interest and negative-equity risk.
- Use current tax and fee quotes; the calculator does not look up local vehicle rules.

Frequently asked questions
Is the answer a lender approval?
No. It is a budget-based estimate using your inputs. Credit, underwriting and the vehicle can change an actual offer.
Why is affordable price different from loan amount?
Cash down, trade equity, tax and fees change how a vehicle price becomes an amount financed.
Should I spend the full estimated limit?
Treat it as a ceiling under your assumptions, not a recommendation. Test higher running costs and leave a reserve.
