Calculation Examples
Example 1: $600 Budget, $150 Fixed Costs
Input Values
Calculation Steps
- Monthly budget: $600
- Fixed costs: $150/month (insurance, parking, registration)
- Available for loan payment: $600 - $150 = $450/month
- Down payment: $5,000
- Loan APR: 5.5%
- Loan term: 60 months
- Calculation: With $450/month payment at 5.5% APR for 60 months, maximum loan amount ≈ $23,000
- Max affordable car price: $23,000 (loan) + $5,000 (down payment) = $28,000
- Monthly loan payment: ~$450
- Total monthly cost: $450 (payment) + $150 (fixed) = $600 (within budget)
Calculated Results
Example 2: Net Income Rule (Moderate)
Input Values
Calculation Steps
- Monthly net income: $5,000
- Income rule: 15% (moderate recommendation)
- Car budget calculation: $5,000 × 15% = $750/month
- Fixed costs: $200/month
- Available for loan payment: $750 - $200 = $550/month
- Down payment: $3,000
- Loan APR: 6.0%
- Loan term: 72 months (6 years)
- Calculation: With $550/month payment at 6.0% APR for 72 months, maximum loan amount ≈ $32,000
- Max affordable car price: $32,000 (loan) + $3,000 (down payment) = $35,000
- Monthly loan payment: ~$550
- Total monthly cost: $550 (payment) + $200 (fixed) = $750 (15% of income)
Calculated Results
Example 3: Bigger Down Payment Impact
Input Values
Calculation Steps
- Monthly budget: $600
- Fixed costs: $150/month
- Available for loan payment: $600 - $150 = $450/month
- Down payment: $10,000 (larger than Example 1)
- Loan APR: 5.5%
- Loan term: 60 months
- Calculation: With $450/month payment at 5.5% APR for 60 months, maximum loan amount ≈ $23,000
- Max affordable car price: $23,000 (loan) + $10,000 (down payment) = $33,000
- Comparison: With $5,000 down = $28,000 affordable. With $10,000 down = $33,000 affordable
- Impact: Extra $5,000 down payment increases affordable price by $5,000
- Monthly loan payment: ~$450 (same as Example 1)
- Total monthly cost: $450 (payment) + $150 (fixed) = $600 (same budget, more car)
Calculated Results
Example 4: High APR Impact
Input Values
Calculation Steps
- Monthly budget: $600
- Fixed costs: $150/month
- Available for loan payment: $600 - $150 = $450/month
- Down payment: $5,000
- Loan APR: 8.0% (higher than Example 1's 5.5%)
- Loan term: 60 months
- Calculation: With $450/month payment at 8.0% APR for 60 months, maximum loan amount ≈ $20,000
- Max affordable car price: $20,000 (loan) + $5,000 (down payment) = $25,000
- Comparison: At 5.5% APR = $28,000 affordable. At 8.0% APR = $25,000 affordable
- Impact: Higher APR (8% vs 5.5%) reduces affordable price by $3,000
- Monthly loan payment: ~$450 (same payment, but less car)
- Total monthly cost: $450 (payment) + $150 (fixed) = $600
Calculated Results
Example 5: Income Rule Conservative (10%)
Input Values
Calculation Steps
- Monthly net income: $4,000
- Income rule: 10% (conservative recommendation)
- Car budget calculation: $4,000 × 10% = $400/month
- Fixed costs: $120/month
- Available for loan payment: $400 - $120 = $280/month
- Down payment: $2,000
- Loan APR: 4.5% (good credit)
- Loan term: 48 months (4 years, shorter term)
- Calculation: With $280/month payment at 4.5% APR for 48 months, maximum loan amount ≈ $12,000
- Max affordable car price: $12,000 (loan) + $2,000 (down payment) = $14,000
- Monthly loan payment: ~$280
- Total monthly cost: $280 (payment) + $120 (fixed) = $400 (10% of income, conservative approach)
