How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Investment amount ($) = 10000, Loan term (months) = 36, Gross interest rate (%) = 12, Expected default rate (%) = 4 = 8 input(s) provided
  2. Calculate Net return
    Net return = grossInterestIncome - netDefaultLoss - lostInterest - platformFees - cashDrag...
    1485.99 = $1,485.99
  3. Calculate Annualized net return
    Annualized net return = loanTermMonths > 0
    4.95 = 4.95%
  4. Calculate Excess return vs. alt
    Excess return vs. alt = netReturn - altReturn
    -14.01 = $-14.01
  5. Calculate Gross interest income
    Gross interest income = totalPayments - investmentAmount
    1957.15 = $1,957.15
