    Understanding how lease payments are calculated gives you the power to evaluate any deal and negotiate from a position of strength.


    The Lease Payment Formula


    Monthly Payment = Depreciation Fee + Finance Fee + Sales Tax


    Step 1: Depreciation Fee

    Depreciation = (Net Cap Cost - Residual Value) ÷ Term in Months


    Step 2: Finance Fee

    Finance Fee = (Net Cap Cost + Residual Value) × Money Factor


    Step 3: Monthly Pre-Tax Payment

    Monthly Payment = Depreciation Fee + Finance Fee


    Step 4: Add Sales Tax

    Total Monthly = Monthly Payment × (1 + Tax Rate)


    Real Example


    Let's calculate the monthly payment for a $40,000 car:

  1. MSRP: $40,000
  2. Negotiated Price (Cap Cost): $38,000
  3. Residual Value (58%): $23,200
  4. Money Factor: 0.00125 (3.0% APR)
  5. Term: 36 months
  6. Tax Rate: 8%

  7. **Depreciation:** ($38,000 - $23,200) ÷ 36 = $411.11

    **Finance Fee:** ($38,000 + $23,200) × 0.00125 = $76.50

    **Pre-Tax Monthly:** $411.11 + $76.50 = $487.61

    **With Tax:** $487.61 × 1.08 = $526.62


    How to Lower Your Payment


  8. Negotiate the cap cost — even $1,000 off saves ~$28/month
  9. Look for manufacturer incentives — rebates reduce cap cost
  10. Choose vehicles with high residuals — less depreciation = lower payment
  11. Compare money factors — a difference of 0.0005 can save $30+/month

  12. The Bottom Line


    Every lease payment breaks down into just two components: depreciation and interest. Understanding this formula lets you evaluate any deal instantly.
