Leasing or Financing? Run This Comparison Before You Decide

Leasing·April 2026·8 min read

There is no one right answer to lease vs. finance. The math turns on how much you drive, how long you keep cars, whether business-use tax rules apply to you, and where the residual value sits on the specific deal in front of you.

Two Structures, Two Different Deals

Financing means buying the car with borrowed money. Each payment retires principal and interest; when the loan ends, the car is yours free and clear, and every month after that costs nothing. Equity builds the whole way.

Leasing means paying for the slice of value the car loses while you have it — the spread between its starting value and its projected residual at term end — plus a finance charge. Ownership never transfers. When the term is up, you hand it back, start another lease, or exercise the purchase option at the residual.

The Conditions That Favor a Lease

The lease math works when several things line up: your driving stays reliably under the mileage cap, you like replacing your car every two or three years, the manufacturer has set a generous residual (which shrinks the payment relative to the car's price), and the money factor sits at or close to the published buy rate.

Business owners get an extra edge: lease payments on a business-use vehicle are generally deductible in full or in part, while purchased vehicles fall under more complicated depreciation rules. Run your specifics past a CPA.

One caveat — cheap manufacturer financing can flip the answer. When 0.9% APR purchase money is on the table, interest costs nearly vanish and the equity you build is real. Always compare total cost across both structures, never just the payments.

The Conditions That Favor Buying

Financing pulls ahead when you pile on miles (lease overage runs $0.15–$0.30 for every mile past the cap), keep cars for eight to ten years, want to modify or customize, or put more wear on a vehicle than a lease inspection will forgive.

Stretch the timeline far enough and ownership nearly always costs less than leasing on repeat. A perpetual lessee makes payments forever; a paid-off car keeps driving for free.

How to Run the Numbers Properly

The honest comparison holds the time horizon constant — six years is the standard frame.

On the lease side: two back-to-back 36-month leases. Add up all payments plus both drive-off amounts; residual equity at turn-in is usually zero.

On the purchase side: one 60–72 month loan. Total the payments and the down payment, then subtract what a six-year-old example of that car is worth on the market today — that's your remaining asset.

Over six-plus years the purchase almost always wins on raw cost. The lease wins on lower monthly outlay and a permanently new, permanently warranted car. Decide based on which of those you actually value — not on whichever monthly payment looks smaller.

Where Meridian Adds Value on Each Path

On leases, we check the money factor against the published buy rate, confirm the residual matches the current factory program, and negotiate the cap cost down before any payment math runs. Working both sides of the formula typically takes $50–$150 off the monthly on a midrange lease.

On purchases, we negotiate the out-the-door price, compare the quoted rate to your actual approval, and go through the F&I paperwork before signature. The rate markup by itself commonly hides $800–$1,500 over the life of a typical loan.
