Frequently Asked Questions — Finance & Commerce
How does an extra monthly prepayment impact total loan interest?
Extra prepayments go directly toward reducing the loan principal. Because interest is computed on the remaining principal balance, extra payments drastically shorten loan tenure and can save thousands of dollars in interest over the life of the loan.
What is the mathematical difference between markup and profit margin?
Markup is the percentage added to cost price to determine selling price: Markup = (Price - Cost) / Cost. Profit margin is the percentage of selling price that remains as profit: Margin = (Price - Cost) / Price. A 50% markup equals a 33.33% profit margin.
