About this app

The Car Loan Payment Calculator turns you into a master negotiator when shopping for a car, truck, boat or RV by quickly and easily calculating a monthly loan payment or an affordable purchase price on location with your mobile device. This will work for a loan on any automobile (auto) or other motor vehicle that can be financed, including RVs and boats.

NEW FEATURE: The app can now calculate a Lease Monthly Payment!

Fully Supports Tablets and screens of all sizes and resolutions (a.k.a., pixel density).

The app can be moved to the SD card. This is the free version of our car payment calculator app.

SAFE - We DO NOT collect any personal information with this app. It only requests the minimum permissions necessary to perform its functions.

At the start screen, you simply choose what you want to calculate:
1. Monthly Loan Payment if buying from a Dealer.
2. Monthly Loan Payment if buying from an Individual.
3. The Price of a Car/Truck/RV that you can afford based on the monthly payment of your choice.

Just enter the required information (e.g., price, interest rate, term of loan), plus any optional information (e.g., trade-in, sales tax rate, rebate, loan payoff, etc.), and then press the calculate button. The trade-In and down payment amounts are separated. This is essential for a good car payment calculator app.

3 main options are available to the user from the start screen:

1. Calculate a Monthly Loan Payment if buying from a Dealer. This option offers allows the user to input all items that a dealer finance manager would input into their system to calculate a monthly loan payment.
User can enter:
1. Price of Car/Truck/RV (required)
2. Trade-In Value (optional)
3. Instant Cash Rebate (optional)
4. Down Payment (optional)
5. Dealer Fees (optional)
6. Miscellaneous - extended warranty, dealer add-ons, etc. (optional)
7. Sales Tax Rate (optional)
8. Interest Rate (required)
9. Loan Payoff (optional)
10. Term of Loan in months (required)

You can also select whether to apply sales tax to the trade-in and/or rebate. You may also choose whether to finance the total sales tax (i.e., include it in the loan). Our car payment calculator app gives you this choice.

The app then calculates the monthly loan payment of the car based on the information above. It will also display the total amount financed and the total sales tax.

2. Calculate a Monthly Loan Payment if buying from an Individual. This is the simplified version.
User can enter:
1. Price of Car/Truck/RV (required)
2. Down Payment (optional)
3. Sales Tax Rate (optional) - used only for informational purposes.
4. Interest Rate (required)
5. Term of Loan in months (required)

The app then calculates the monthly loan payment of the car based on the information above.

3. Calculate the Affordable Purchase Price of a car based on the monthly loan payment interest rate, term of loan and any other optional information.
User can enter:
1. Monthly Payment of Car/Truck/RV (required)
2. Trade-In Value (optional)
3. Down Payment (optional)
4. Dealer Fees (optional)
5. Miscellaneous - extended warranty, dealer add-ons, etc. (optional)
6. Sales Tax Rate (optional)
7. Interest Rate (required)
8. Loan Payoff (optional)
9. Term of Loan in months (required)

You can also select whether to apply sales tax to the trade-in. You may also choose whether to finance the total sales tax (i.e., include it in the loan). Not all car payment calculator apps give you this choice.

The app then calculates the affordable purchase price of the car based on the information above. It will also display the total amount financed and the total sales tax.

Thank you for your feedback. You can close the pop-up ads after they finish showing their video. It won't show again for at least 4 hours. Or you could buy the pro version. You have a choice. The ads are unfortunately necessary but I will look into how the ads work and display. Indie devs have to eat. Have a nice day!

This is a very useful, and cost free financial calculator. It basically eliminates the need to understand the math to calculate car payments. With this app It's very simple to quickly test different financial scenarios by adjusting the length of the loan, the initial deposit, the interest rate, total purchase price, or any trade in value that may be applied to the cost of the new purchase.
