Lease Vs Buy Car Calculator
The Lease vs Buy Calculator is a decision-making tool that compares the true cost of leasing a vehicle versus purchasing it with a loan. It factors in:
- Vehicle price
- Sales tax
- Interest rates
- Loan or lease terms
- Down payments
- Residual value
- Equity when buying
Instead of looking at monthly payments alone, the calculator highlights the real financial impact of each option over the same time period.
Why Comparing Lease vs Buy Matters
Many people choose a car option based only on the monthly payment. This can be misleading.
- Leasing usually offers lower monthly payments
- Buying builds long-term ownership and equity
- Leasing has mileage limits and no ownership
- Buying costs more upfront but saves money long term
This calculator eliminates confusion by showing both options side by side, helping you avoid costly mistakes.

Example Comparison
Let’s look at a realistic example.
Car Price: $30,000
Sales Tax: 7%
Lease Option
- Term: 36 months
- Interest rate: 5%
- Residual value: 55%
- Down payment: $2,000
Result:
- Monthly lease payment: ~$420
- Total lease cost: ~$17,100
Buy Option
- Loan term: 60 months
- Interest rate: 4.5%
- Down payment: $2,000
Result after 36 months:
- Monthly loan payment: ~$560
- Net cost after equity: ~$14,800
- Equity value: ~$16,500
Although leasing looks cheaper monthly, buying costs less over time due to ownership value.
Understanding Key Terms
Residual Value
Residual value is the estimated worth of the vehicle at the end of the lease. A higher residual lowers lease payments but reduces flexibility.
Equity
When buying, equity is the portion of the car you own as you pay down the loan. This equity reduces the true cost of ownership.
Net Cost
Net cost accounts for money paid minus the vehicle’s remaining value. This gives a more accurate comparison than payments alone.
