The Formula Behind Auto Loan Calculations
Auto loans typically use amortized loans, where monthly payments cover principal and interest. The monthly payment is calculated with the formula: P=r×PV1−(1+r)−nP = \frac{r \times PV}{1 – (1 + r)^{-n}}P=1−(1+r)−nr×PV
Where:
- PPP = monthly payment
- rrr = monthly interest rate (APR divided by 12 and converted to decimal)
- PVPVPV = present value or loan amount
- nnn = total number of monthly payments (loan term)
Example Calculation
Suppose you want to finance $25,000 with:
- APR: 5% annually
- Loan term: 60 months
Step 1: Convert APR to monthly interest rate
r=5100÷12=0.004167r = \frac{5}{100} \div 12 = 0.004167r=1005÷12=0.004167
Step 2: Plug into the formula
P=0.004167×25,0001−(1+0.004167)−60=104.171−(1.004167)−60P = \frac{0.004167 \times 25,000}{1 – (1 + 0.004167)^{-60}} = \frac{104.17}{1 – (1.004167)^{-60}} P=1−(1+0.004167)−600.004167×25,000=1−(1.004167)−60104.17
Calculating the denominator: 1−(1.004167)−60=1−0.778=0.2221 – (1.004167)^{-60} = 1 – 0.778 = 0.2221−(1.004167)−60=1−0.778=0.222
So: P=104.170.222≈469.70P = \frac{104.17}{0.222} \approx 469.70P=0.222104.17≈469.70
Your monthly payment is approximately $469.70.
