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

Recurring:

You can schedule two automatic recurring payments per month.  Automatic recurring payments will occur on the same day every month. If you choose to set up bi-monthly 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 automatic bi-monthly payments 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.
