Every time you login to Lending Club you are greeted with your Net Annualized Return number on the home screen. But is this the actual return you are getting on your money? Let me share my results with you to give you an idea.
I began investing in Lending Club July 2009 with just $500, split between two notes (one of which defaulted after 9 months). As I mentioned in a previous post this lack of diversification was a big mistake. I invested another $10,000 in August 2009 (more diversified this time) and since then I have invested no new money in this account. Last year I did rollover my wife’s IRA into a Lending Club IRA but that account is only six months old so it is too young to really give us a good indication of actual vs stated return. My account on Prosper has been open less than six months as well so I won’t be including either account in this analysis.
My main Lending Club account has 304 notes, primarily grades A, B, and C with a median loan age of 15 months. On December 31st, 2010, Lending Club maintained that my Net Annualized Return (NAR) was 7.64%. So, I calculated what my real world return was. It was a very simple process because I had not added or withdrawn money from my account in 2010. My starting balance on January 1, 2010 was $10,792 and my ending balance on December 31, 2010 was $11,547. This equates to a return of exactly 7.0%, or 0.64% less than Lending Club states.
The Difference Between Real and Stated NAR
Why is there a difference between my actual return and the return that Lending Club states? The main reason can be summed up in one word: cash. The Lending Club formula assumes that all your money is 100% invested in notes all the time. But in reality that can’t happen. Once you decide to invest in a note it will take several days for the funds to be released to the borrower. Meanwhile that money is just sitting there earning 0% interest. Then once you have some loans in place, if you have more than a handful of loans you are receiving interest and principal payments on a daily basis. This money stays in your account earning o% as well until you reinvest it.
Lending Club does take into account loan defaults in calculating your NAR, so whenever you have one you will notice a dip in your NAR. Your NAR will change regularly because it is calculated every day for you. If you go for several days or weeks without a default you will likely see it creep up. As you invest in new notes, particularly higher interest notes, you will also see it creep up.
Prosper Takes a Different Approach
With Prosper you are not greeted with a big NAR number staring at you when you login like you are at Lending Club. Prosper sends out monthly emails with your “Prosper ROI” but they don’t display it on their web site for you. From the monthly email they share how your NAR is calculated:
Returns include all payments received net of principal repayment, credit losses, and servicing costs for Notes not bought or sold on Folio. Returns are divided by the average daily amount of principal outstanding to get a simple rate of return. This rate is annualized by dividing by the dollar weighted average Note age of your portfolio in days and multiplying by 365.
It is a slightly different formula to Lending Club, but I am not an expert mathematician so I can’t provide much feedback as to which one is more accurate. They both take into account defaults and service fees. Anyway, you shouldn’t rely on either company’s metrics, you really should do you own calculation to determine your actual NAR.
How to Calculate Your NAR for Lending Club or Prosper
The good news is that it is relatively easy to calculate your own real world NAR in an Excel spreadsheet. You can use the XIRR function within Excel to do the hard work for you. All you need is a list of all the deposits and withdrawals you made on your account and their respective dates as well as the starting and ending balance. You put the deposits in as negative numbers and the withdrawals as a positive number, then the final balance should be a positive number. Lets’s take a look at this simple example here. On January 1, 2010 $10,000 was invested; three further deposits were made on 2/1/10, 5/5/10 and 6/30/10. A $300 withdrawal was made on 11/15/10 and the closing balance of $11,489 results in a 11.48% annual return. There are examples and further explanations of XIRR() in Excel’s help as well as here.
Past Performance is No Guarantee of Future Returns
You see this disclaimer throughout the financial services industry and it certainly applies here as well. The thing about NAR is that it is always going to be best when most loans in your portfolio are young. As of right now the median age of loans on Lending Club is slightly less than nine months. This means that the majority of loans are still very young and haven’t even had much of a chance to default. So, even though the Lending Club claim of 9.68% average returns and Prosper’s claim of 10.4% is technically correct, it is somewhat misleading. In the real world your returns will be less than that as I demonstrated in my example above. Also, the average return for all p2p investors will likely be lower than claimed once all loans have been held to maturity and all defaults have been taken into account.
If you really want an accurate picture of your returns on your p2p investments it is important to calculate it yourself. It appears that Lending Club overstates the return by between 0.5% and 1%, and my guess is that Prosper does this as well. It is also a good idea to temper your expectations, because your returns may well go down as your loans age and some defaults become a reality. Even with these lower expectations and overstated returns, I still believe that with p2p lending you can a great return on your money.
