Lease wording for discount for on time payments

[Justin Ford]

Can someone help me with some legal wording for our lease regarding discount for on time payments. We are charging no late fees, but if they are on time, giving a discount. We are upping the rent by $50 and then giving them a discount for paying on time of $50 per month. I just need to know how to word that correctly. If anyone does this, and has it in their lease, I would appreciate you sharing that wording. Thank you!
