Implicit costs can also be thought of as intangible costs that are not easily accounted for. For example, the time and effort that an owner puts into the maintenance of the company, rather than working on expansion, can be viewed as an implicit cost of running the business.
For example, if you borrow $100,000 from your brother and promise to pay him back all the money plus an extra $25,000 in 5 years, you are paying an implicit interest rate. There are other situations in every day life where you will encounter implicit interest rates.
