Swifty expected to complete the building by December 31, 2020. Swifty has the following debt obligations outstanding during the construction period. Construction loan-12% interest, payable semiannually, issued December 31, 2019 $5,000,000 Short-term loan-10% interest, payable monthly, and principal payable at maturity on May 30, 2021 3,500,000 Long-term loan-11% interest, payable on January 1 of each year.

Compute the avoidable interest on this project. (Use interest rates rounded to 4 decimal places, e.g. 7.5825% for computational purposes and round final answers to decimal places, eg, 5,275.)
