Yes, you can make your monthly payment in two installments. 

AutoPay:

You can schedule two AutoPay payments per month.  Automatic payments will occur on the same day every month. If you choose to set up twice a month payments, you will need to do so at least 15 days before your next due date.  Please allow 3 business days for changes to your recurring payments to take effect.

Manual:

If you are not eligible for twice a month AutoPay or you prefer to make manual ACH payments, you can make a split payment on your Upstart dashboard by scheduling 2 one time payments using the “Make a Payment” button. 

As a reminder, your promissory note states a 10 day grace period and Upstart offers 5 additional days as a courtesy before assessing a late fee, for a total of a 15 day grace period. A late fee will assess if your account falls 16 days past due.
