A lease is a legal agreement that fixes the terms for using a property, such as a flat or a car, over a set period. Rent is the payment a tenant makes for that use, and renting can also describe a shorter, more flexible arrangement without a fixed term. You sign a two-year lease on an apartment, but you might rent a car for just a week.
The core difference
A lease is the formal agreement and its fixed term; rent is the payment made, and can also mean a looser, shorter arrangement.
- lease — a legal agreement to use property for a set time in exchange for payment: They signed a two-year lease on the apartment.
- rent — the regular payment a tenant makes, or the act of paying for temporary use: We rented a car for the week we were in Spain.
How to tell them apart
Both words can act as verbs for the same transaction, which is where the confusion creeps in. A company can lease office space, meaning it signs a fixed-term contract, while renting often implies something shorter or more casual, like renting a car for a week or a room to a student.
A quick memory hook: lease comes from an old root meaning to let go or loosen, tied to a fixed release of property for a period, while rent traces back to a root meaning to give back, matching the regular payment handed back to the owner. Rent is also, unrelatedly, a word for a tear in fabric.
