Debt Accumulation

each year, we create this percentage of our GDP as new debt

each year, we pay off this percentage of our total debt

each dollar of new credit creates this many pennies of GDP

since we are not modeling inflation, this should be the 'real' interest rate


Your results:

(New Credit Use: 40%; Debt Repayment: 10%; GDP Boost from New Credit Use: 80%; Interest Rate: 3%)
