What Is a Sum of Money?

A specific amount of money, usually in the form of coins or banknotes that can range from small amounts to vast fortunes. This term is often used in financial transactions, budgeting, economics, and any context involving monetary exchange or calculation.

A sum certain is an amount of money that is directly stated in a contract or other negotiable instrument at the time it is written. This eliminates room for misunderstanding or misinterpretation in terms of what is owed. For example, a contract that stipulates, “Alice will pay Bob $8,000 for painting her house including all costs” is a sum certain.

The time value of money is the concept that a single dollar today has more value and utility than a similar amount received at some future date, because it can be spent or invested now. This is the reason why you should always consider the time value of money when making financial decisions, especially ones involving investments and loans. The time value of money can be calculated using a variety of formulas depending on whether you want to know the present or future value of the cash flow, and in which direction (forward or backward) you want to evaluate it. For example, if you are considering whether to invest or accept a lump-sum payment from a lottery winning, you will need to take into account the tax situation, interest rates, and how long you want to receive the payments (i.e., lump sum or yearly). סכו״ם כסף
