The imputed interest rate is an unstated interest rate and it can cover many different scenarios. To calculate an imputed interest rate, you need to input the actual cash flows and then you can solve for the interest rate.

The magic of compounding can work to your advantage when it comes to your investments and can be a potent factor in wealth creation. While simple and compound interest are basic financial concepts, becoming thoroughly familiar with them will help you make better decisions when taking out a loan or making an investment, which may save you thousands of dollars over the long term.  When investing, compounding is critical. You'll start earning interest on your initial deposit and you'll earn interest on the interest you just earned.

Occasionally a customer asks whether making half monthly payments instead of monthly payments will pay off their mortgage quicker.  The answer is no.   Let’s assume a 30-year loan. You will only save part of one month’s interest over the 30 years so it is probably not worth it and this is assuming that your bank will process your partial half month payments timely.

Often, we have no activity on a loan or an investment but we want to know the amount of interest that is accruing or compounding. You can trigger the interest to appear by adding events such as a Payment or Invest for a $0 amount. This causes TValue to calculate the interest and, depending on the compute method, either add it to the principal if you are using Normal (compound interest) or to the accrued interest balance if you are using US Rule (simple interest).

There are some penalties that are pretty straight forward and then there is the IRS Failure to File (FTF) penalty 6651(a)(1).  The FTF is a 5% per month penalty to a maximum of 5 months or 25% from the due date or the extension date, whichever is later. If the FTF and the Failure to Pay (FTP) penalty run simultaneously, you only pay 4.5% for the FTF penalty and it caps out at 22.5% as the IRS is limiting the combination of the two penalties to 5% overall.  That is the good news.
