This assistant creates a loan repayment scheduled transaction. When used to setup a scheduled transaction, the assistant creates a variable formula so that the compounding interest is correctly calculated. To start this assistant manually go to Actions → Scheduled Transactions → Mortgage and Loan Repayment. .

It does not support zero-interest loans, but one doesn't really need an assistant for that: Just create a scheduled transaction for the principal divided by the number of payments that lasts for the number of payments. For example, if one has borrowed $1200 for a year at no interest and promised to pay it back in monthly installments, the repayment schedule is $100 monthly for twelve months.

The Mortgage and Loan Repayment assistant opens with a screen that briefly describes what this assistant does. The three buttons at the very bottom of the screen will not change while using the assistant.

• The Cancel button is used to exit the assistant and cancel creating the scheduled transaction. Any selections you have made in this assistant up to this point will be lost.
• The Back button will bring up the previous screen so you can change a selection made on that screen.
• The Forward button will bring up the next screen so you can continue though the assistant.

The next screen allows you to enter the basic loan information. This is usually the information provided by the bank when loan and disclosure documents are given to the borrower. Here you can also setup an account that the scheduled transaction will use to enter the payment transaction.

• Loan Account Choose an account for the loan payment transactions or use New. to setup a new account for the transactions.
• Loan Amount Enter the amount of the loan.
• Interest Rate Enter the loan interest rate in percent per compounding period. The Assistant supports rates between .001% and 100%.
• Type Choose the type of loan. If an adjustable rate is used the frequency screen is enabled.
• Interest Rate Change Frequency Choose the frequency for the rate change and the start date of the rate change.
• Start Date Choose the date the loan is starting on.
• Length Enter the length of the loan with the number and period, e.g. 60 months or 5 years.
• Months Remaining This tells the Assistant how many months remain on the loan. The default value assumes that the loan is paid up through today. For example, if a 5-year loan started on 1 January 2012 and today is 12 July 2015, the default months remaining is 18. If you want to create past payment transactions you'll set the months remaining accordingly: In our example, if you wanted to create all of the payments you'd set "months remaining" to 60; if you wanted to start tracking the payments at the beginning of 2015 you'd enter 24.
