IvanhoeFurniture Company started construction of a combination office and warehouse building for its own use at an estimated cost of $ 4,000,000 on January 1, 2020. Ivanhoe expected to complete the building by December 31, 2020. Ivanhoe has the following debt obligations outstanding during the construction period.

Construction loan- 12% interest, payable semiannually, issued December 31, 2019		$ 1,600,000
Short-term loan- 10% interest, payable monthly, and principal payable at maturity on May 30, 2021		1,200,000
Long-term loan- 11% interest, payable on January 1 of each year. Principal payable on January 1, 2024		800,000

Assume that Ivanhoe completed the office and warehouse building on December 31, 2020, as planned at a total cost of $ 4,160,000, and the weighted-average amount of accumulated expenditures was $ 2,880,000. Compute the avoidable interest on this project. (Use interest rates rounded to 2 decimal places, e.g. 7.58% for computational purposes and round final answers to 0 decimal places, e.g. 5,275.)
