Math Problem Statement
Purchase Costs Down payment $ 1,700 Loan payment $ 440 for 36 months Estimated value at end of loan $ 5,800 Opportunity cost interest rate 8 percent Leasing Costs Security deposit $ 890 Lease payment $ 550 for 36 months End of lease charges $ 870 Based on the costs listed in the table above, calculate the costs of buying and of leasing a motor vehicle.
Solution
To calculate the total costs of buying and leasing the motor vehicle, let's break it down step by step.
1. Cost of Buying:
-
Down payment: $1,700
-
Loan payments: $440 per month for 36 months.
Total loan payments =
-
Estimated value at end of loan: $5,800 (this is the residual value of the vehicle, which reduces the total cost of ownership)
However, we need to account for the opportunity cost of tying up money in the down payment and loan payments. To do this, we apply the opportunity cost interest rate of 8%.
Formula to calculate opportunity cost on loan payments:
The opportunity cost of money that could have been invested elsewhere can be estimated using the future value formula for the down payment and monthly loan payments.
-
Down payment opportunity cost:
The future value of the down payment (FV) can be calculated as: where:
- = $1,700 (initial down payment),
- = 0.08 (annual interest rate),
- = 3 years (duration of the loan).
The opportunity cost here is .
-
Loan payment opportunity cost:
Since these are monthly payments, we'll use the future value of an annuity formula: where:
- = $440 (monthly loan payment),
- (monthly interest rate),
- months (number of payments).
Plugging in the values: The opportunity cost here is .
-
Total opportunity cost for buying:
Now, subtract the residual value of the vehicle from the total cost:
2. Cost of Leasing:
-
Security deposit: $890
-
Lease payments: $550 per month for 36 months.
Total lease payments =
-
End of lease charges: $870
Adding these together:
3. Final Comparison:
- Cost of buying: $14,049.75
- Cost of leasing: $21,560
Therefore, buying the vehicle is more cost-effective than leasing by a difference of:
Conclusion:
Buying the vehicle would cost approximately $14,049.75, while leasing it would cost about $21,560 over the 36-month period. Thus, buying would save you $7,510.25 compared to leasing.
