Which term refers to changes in the cost or price of specific goods or services over a period of time?

• A. Time Value of Money
• B. Cost Escalation
• C. Marginal Tax Rate
• D. Net Present Worth

Answer: (B)

Cost escalation is the term used for changes in the cost or price of specific goods or services over a period of time. It captures how materials, labor, and subcontracted items can become more expensive as time passes due to inflation, market dynamics, or supply constraints. In budgeting and procurement, applying escalation factors to future costs helps create realistic budgets and manage financial risk over the project’s timeline. For contrast, the time value of money is about money’s relative worth changing over time because it can earn interest. Net present worth (present value) reflects discounting future cash flows to their value today. Marginal tax rate refers to the tax rate applied to the last dollar of income. None of these describe how the prices of specific goods or services are expected to move over time in cost estimates.
