Lease vs Buy Calculator

Free Lease vs Buy Calculator: calculate lease vs buy instantly with transparent formula, worked examples and tips. No signup.

A lease vs buy calculator compares the total cost of obtaining a vehicle through a personal contract hire (PCH) or finance lease against outright purchase or hire-purchase (HP) financing. With a lease, you pay a fixed monthly lease payment covering depreciation and a finance charge over the contract term, then return the vehicle with no ownership and no residual value risk. Buying (on loan or outright) means you own the asset and accumulate equity in its residual value, but you bear the full depreciation and any negative equity risk if values fall faster than expected. Loan Payment Calculator models the depreciation component in isolation to inform this comparison.

The correct comparison is total cost of access over the same period, not monthly payments: lease total (deposits plus all monthly lease payments plus any excess mileage penalties) versus buy net cost (purchase price plus finance charges minus residual value at sale or part-exchange).

Enter the vehicle's list or agreed purchase price (the cap cost that determines the monthly lease payment).
For leasing, enter the monthly lease payment, initial rental (deposit equivalent), and contract term in months.
For buying on finance, enter your deposit, interest rate (APR), and loan term.
Enter the expected residual value at end of period for the buy option — what you would sell or part-exchange it for.
Compare total costs: sum of all lease payments vs net buy cost (purchase price plus total interest paid minus residual value).

Lease vs buy cost formulas

Total lease cost = Initial rental + (Monthly lease payment × Term in months) + Excess mileage charges + End-of-contract fees

Total buy cost = Purchase price + Total interest paid − Residual value at sale

Monthly lease payment ≈ (Net cap cost − Residual value) ÷ Term + Monthly finance charge

Worked example: Car list price $35,000. Lease: $3,000 initial rental + $450/month × 36 months = $19,200 total. Buy: $35,000 + $2,100 interest − $15,000 residual value = $22,100 net cost. Leasing saves $2,900 over 3 years in this scenario before factoring in mileage penalties.

When leasing wins vs buying

Key decision factors

Leasing typically wins when: you want a fixed predictable monthly lease payment with no residual value risk; you change vehicles frequently (every 2–4 years); eligible business users can deduct lease costs under their local tax rules. Buying wins when: long-term ownership (5+ years) reduces per-year depreciation cost; you drive high annual mileage (excess mileage penalties eliminate the lease cost advantage); you want equity for the next vehicle. Loan Payment Calculator and Mortgage Calculator model individual cost components to support this decision.

Finance tips and best practices

Negotiate the cap cost (the agreed vehicle price feeding into the lease) just as you would negotiate a purchase — every $1,000 reduction in cap cost reduces the monthly lease payment by approximately $20–28/month on a 36-month term.
Compare total cost of access over the same period, not monthly payments — a lower monthly lease payment over 48 months often costs more in total than a higher payment over 36 months.
Understand your mileage allowance carefully — many lease contracts charge about $0.15–$0.30 per excess mile; high-mileage drivers frequently find buying significantly cheaper over three years.
Check for purchase option fees at the end of a PCP deal — the option-to-purchase fee plus balloon payment can make keeping the car more expensive than part-exchanging or re-leasing.

Many new private cars are acquired with finance; compare the financed amount, total interest, lease term, and residual value rather than relying on the monthly payment alone.
A mid-size family car lease may be quoted around $300–500/month before taxes, fees, mileage limits, and upfront payments; compare the complete contract.
Excess-mileage charges are commonly stated per mile, so even a small rate can materially change a high-mileage driver's total cost.
Business tax treatment of lease payments varies by jurisdiction and private use; confirm eligible deductions with a local tax adviser.

Common mistakes to avoid

Comparing monthly lease payment to monthly loan payment as though they were equivalent — loan payments build ownership equity; lease payments do not; always compare total cost of access.
Underestimating annual mileage — exceeding the contracted mileage allowance triggers per-mile penalty charges that can eliminate the cost advantage of leasing entirely.
Ignoring fair wear-and-tear standards — vehicles returned with damage beyond manufacturer-accepted wear incur refurbishment charges; repair obvious damage before contract end.
Not factoring GAP insurance — if a leased vehicle is written off, standard insurance pays market value which may be less than outstanding lease liability; GAP cover bridges this shortfall.

Vehicle leases and finance agreements are regulated products whose disclosures, consumer protections, tax treatment, and early-termination rules vary by jurisdiction. Always read the full terms and conditions, including mileage allowance, fair-wear standards, fees, and end-of-contract charges before signing. Business deductions depend on local rules and private use; consult a qualified tax adviser. Early termination charges can be significant, so check the contractual calculation before exiting a lease early.
