You go to a car dealership on your day off and end up buying a car that you love. You get financing at the dealership and get a call from a bank introducing itself as your lender. They tell you that your loan is due on the day of the month that you happened to buy the car, even though it’s 8 days from your payday. And they mention that they’ll send you a letter in the middle of each month reminding you to pay, but your payday is at the end of the month, and you don’t actually read your mail very often. Repaying your car loan seems like it could be easier…
Prior research has found that financial shortfalls – particularly payday loans and bank overdrafts – are more common when there is a greater mismatch between the timing of someone’s income and the bills they owe.
We also hypothesized that it is easier for people to pay money automatically and in smaller amounts timed with when they get paid.
We encouraged a number of process changes, which included:
- Allowing changes to loan due date before first loan payment
- Encouraging changing loan due date to align with income at onboarding
- Text message payment reminders
- Emailing automatic payment forms at the pre-funding verification call
- Pre-populating known information on the automatic payment forms
Additionally we ran an experiment which randomized over 700 people into either:
- An experimental condition in which they were texted an automatic payment form encouraging them to set up automatic payments when they are paid;
- A control condition in which they were only asked about their interest in this type of service.
Our process changes contributed in part to a 69% reduction in loan charge-offs year-over-year in a rising subprime auto loan default environment.
Our experiment doubled the number of people enrolling in automatic payments and increased the number of people making more than 1 payment per month from 6% to about 25%.
