Debt service refers to the total amount of money paid by a borrower to a lender, including both interest payments and principal repayments, over a specific period of time. This term is commonly used in finance and accounting to describe the cost of borrowing and is a critical metric for assessing the sustainability of a borrower's debt load.

Debt rescheduling is a formal agreement between a debtor nation and its creditors to adjust the original terms of a loan. This is usually triggered when a country faces a liquidity crisis and cannot meet its scheduled payments. The process may involve extending the maturity date, lowering interest rates, or providing a grace period to prevent default.

Debt retirement refers to the process of paying off a debt obligation in full. Once the principal amount and any accrued interest are paid back to the creditors, the debt is considered retired or extinguished. This is distinct from rescheduling or refinancing, as it represents the final settlement and removal of the liability from the balance sheet.

The marginal tax rate is the tax percentage applied to the last dollar of income earned. Because individuals make decisions about working an extra hour or investing more capital based on the return they keep after taxes, the marginal rate is the critical factor that distorts economic choices. It directly impacts the incentive to earn additional income, whereas average rates reflect the total tax burden.
