5. Frequently Asked Questions (FAQ)

Q1: Why is 2400 used in the conversion?
A: 2400 combines two conversions: multiplying by 100 (to convert decimal to percentage) and by 24 (to convert monthly rate to annual).

Q2: What is a good Money Factor?
A: A good MF depends on credit. Excellent credit might get 0.0010 (2.4% APR), while average might be 0.0025 (6% APR).

Q3: Can Money Factor be negotiated?
A: Yes, though dealers may call it "buy rate." Those with good credit can often negotiate lower Money Factors.

Q4: Why do leases use Money Factor instead of APR?
A: It's an industry standard that makes lease calculations simpler, though it can obscure the true interest cost.

Q5: How does Money Factor affect monthly payments?
A: Higher Money Factor directly increases the finance portion of your lease payment. A difference of 0.001 can add $20-$40/month to a typical car lease.
