PIK Interest, or "Paid-in-Kind" interest, is a feature of debt that allows interest expense to be accrued for a set number of years, rather than be paid in cash in the current period. In exchange for the deferred payout of the cash interest expense and the borrower retaining the cash for additional time, the debt principal coming due on the date of maturity increases. (WallStreetPrep)

Unlike normal Interest on Debt, PIK Interest (PIK = “Paid-in-Kind”) accrues to the loan principal rather than being paid in cash, which results in an increasing loan balance and higher interest payments in the future. (Breaking Into Wall Street)

Paid In Kind (PIK) interest, a feature of some debt instruments, refers to the interest expense that is not paid in cash but is accrued (or rolled up) onto the balance of the loan. In the following year after issuance of the debt instrument, interest is charged both on the existing loan and the rolled-up interest. (Financial Edge)
