> The money factor calculator converts a car lease money factor into the equivalent annual interest rate (APR) and back, and estimates the monthly finance charge on a lease.

## Inputs

- Money factor
- Net capitalized cost
- Residual value

## Results

- Equivalent APR
- Monthly finance charge

## Formula

```
APR = money factor × 2,400
Money factor = APR ÷ 2,400
Monthly finance charge = (net capitalized cost + residual value) × money factor
```

## Explanation

Car dealers quote lease financing as a money factor – a small decimal like 0.00250 – which hides the fact that it equals a 6% interest rate. Multiplying by 2,400 makes it easy to compare with loan rates.

### How to use the Money Factor Calculator

- **Money factor**
- **Net capitalized cost**
- **Residual value**
- Every result field is editable: type into **Equivalent APR** and **Money factor** plus every other field update to match.

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the money factor (or type an APR into the result), and optionally the capitalized cost and residual value.

### Tips

- Use the nominal annual rate and pick the compounding frequency your bank or broker states.
- Small differences in return or fees compound into large differences over decades.
- Run the calculation with a cautious, a central and an optimistic return to see the range of outcomes.
- Past returns do not guarantee future returns – nothing here is investment advice.

### Common mistakes to avoid

- Comparing an APR with an APY or effective rate.
- Ignoring inflation, taxes and fees when judging a real return.
- Entering a percentage as a decimal (5 instead of 0.05 is correct here).
