Calculating monthly car payment
Input
Car price: $35,000, Down: $5,000, Rate: 5.9%, Term: 60 months
→
Output
Loan amount: $30,000
Monthly payment: $579.98
Total interest: $4,798.80
Total cost: $39,798.80
Monthly payment uses the standard amortization formula. At 5.9% for 60 months, you pay $4,799 in interest on a $30K loan.
Comparing 48 vs 72 month terms
Input
Loan: $25,000, Rate: 6%, Terms: 48 and 72 months

- An investment strategy where a fixed amount is invested at regular intervals regardless of price. This approach reduces the impact of market volatility over time.
- Return on Investment (ROI)
- A performance measure that evaluates the efficiency of an investment by dividing net profit by the cost of investment, expressed as a percentage.
- Net Worth
