The Edge's 3 year residual value has been set at 51%, meaning after 3 years, the Edge is anticipated to retain 51% of its original value. When you finance a vehicle, you are paying for the entire vehicle and building equity at the same time, so when you are finished paying it off you own the vehicle in return. When you lease a vehicle, you're paying essentially only for the depreciation but you never build any equity unless you decide to purchase it at the end of the lease term. So if the residual is 51%, that means the depreciation is 49%. The lower the amount of depreciation (higher residual), the lower your payments will be with all other things being equal. When a vehicle's depreciation is high (residual value is low), your lease payments will be higher. There is a way around that where the manufacturer can subvent (subsidize) the lease. In this case, the manufacturer artificially increases the residual value of the car for the purposes of the lease in an attempt to make the lease affordable. Of course, the manufacturer basically eats it at the end because they have essentially paid extra to get you to lease the car, but when the car is returned after the lease is up, they cannot sell it for the artificially increased price. So when the residual value is relatively high, it is a Win-Win situation for the person leasing and for the manufacturer. You get a lease at a good monthly payment, and the manufacturer doesn't have to spend extra money to give you a good deal on the lease.
