Can I model a loan whose interest is added to its balance?
Where to find it: LOANS → Edit → Modify payments
Yes. Open LOANS, select Edit for the loan, then choose Modify payments.
For an amortizing loan, enter 0 as the new payment amount and leave Percentage increase blank. Enter the beginning and end of the period without payments. During that period, no payment is made and unpaid interest is added to the loan balance. Regular payments resume after the period ends.
For a line of credit or credit card, enter -1 instead to stop interest payments and add that interest to the balance. On those forms, 0 means no extra principal repayment; interest is still paid.
Save the change and run TIME MACHINE to see the loan balance and cash flow. For an amortizing loan, you can also select Amortize in LOANS to inspect the payment schedule.
