Questions this tool helps answer
Compare the result, cost, and tradeoffs.
- How much cash down is needed to reach the selected monthly payment?
- How do trade equity and rebates reduce the financed balance?
- Does the transaction already fit within the selected payment capacity?
Method
How the calculation works
The calculator converts the target payment into the maximum principal supported by the rate and term. It then compares that capacity with the complete transaction balance after trade equity and rebates.
Important definitions
Understand the result.
- Maximum supported principal
- The financed balance that corresponds to the selected payment, annual rate, and term.
- Effective down payment
- Cash down plus positive trade equity and rebates.
- Payment capacity
- Unused supported principal when the transaction already fits below the selected payment.
Important limitations
Verify material decisions.
The result is not a lender approval or required minimum down payment. Taxes, fees, trade values, negative equity, lender limits, and final contract terms may change the actual cash required.
Use the calculator as an educational comparison tool and confirm important figures with source documents, providers, lenders, taxing authorities, or qualified professionals as appropriate.
