It also for simplicity purposes, assumes that 30% of principal was repaid on all charge off loans before they went late and subsequently charged off.
This is a major problem. "Default rate" is the rate at which loans default, just like "death rate" is the rate at which people die. Now if the government decided one day that they wanted to show you a smaller number for a death rate due to whatever, they might start saying well old people have lived most of their normal life already, so we'll count them as only a fraction of a death. That's what you're describing above.
To use the default rate in the standard calculations of return, one needs a number that is the rate at which loans default. It appears that LC doesn't calculate that.
I could calculate it myself, but it requires some work. LC's web site doesn't allow me to see how many loans are in what state as of a given observation date. Used to, but they removed the observation date feature. Therefore I can no longer grab numbers from their web site and plot curves as I do for prosper. I could of course download the whole database and do some massive crunching, but that increases the cost to me by a lot, so I haven't done it.
What does this mean exactly Fred? Sorry a little confused, a lot of your math has always been beyond me.
The 30% default rate that I "assumed" was based on rough numbers that went something like this when I analyzed their full database last month.
$1,000,000 principal loaned to individuals that had defaulted/charged-off
$300,000 principal and interest combined paid on these charged off/default notes leaving a net loss of 70% on default / charge-offs
I just re-downloaded the data. If you limit the data to all loans originated before April 1, 2009, and limit the loan purpose to Credit Card Payoff and Debt Consolidation, you get the following (rounded to the nearest dollar):
Principal Borrowed : $19,994,575
Remaining Principal : $9,046,909
Payments to Date : $13,572,508
Now, look at charge-offs and defaults.
Principal Borrowed : $2,449,175
Remaining Principal : $1,868,557
Payments to Date : $818,733 (Principal + Interest)
Interest Payments : $238,115
Leaving 76.3% of principal unpaid, however, earned interest of 9.7% (not annually). So I definitely took some liberty rounding these numbers off, and it doesn't help us with an annualized default rate, but it does give an accurate picture of total dollar value defaults.
Roughly 30% of principal lent, is repaid (if you include interest payments) when a loan defaults or charges-off.
By the way (1,868,557/19,994,575 = 0.0934 or
9.34% of total Principal lent prior to April 01, 2009 has charged-off or defaulted. This data does not include any lates.
Not sure if this really helps anyone but the data seems meaningful to me...
