Money's value changes over time due to factors like , , and . This concept forms the basis of financial decision-making, with quantifying the . Higher rates indicate greater time value.
and are key concepts in time value calculations. represents money's worth at a future date, while present value is the current worth of future money. These calculations are crucial for evaluating investments and financial planning.

Money has a time value due to:
involves the potential earnings lost by not investing money available now (savings account, stocks)
Inflation erodes the purchasing power of money over time as prices increase (consumer goods, services)
Risk and make future cash flows less certain than present cash flows (economic conditions, market volatility)
rates quantify the time value of money
Higher interest rates indicate a greater time value of money (10% vs 2% annual return)
The relationship between time and money value forms the foundation of financial decision-making ( choices, budgeting)
Future value vs present value
Future value (FV) represents the value of a sum of money at a specific future date
Calculated by applying to a present sum over a given time period (5 years, 10 years)
Formula: FV=PV(1+r)n
PV = Present value (initial investment)
r = Interest rate per period (annual, quarterly)
n = Number of periods (years, months)
affects the growth rate of investments (daily, monthly, annually)
Present value (PV) represents the current value of a future sum of money
Calculated by a future sum at a given interest rate over a specific time period
Formula: PV=(1+r)nFV
Key differences between future value and present value:
Direction of time
Future value projects a present sum forward in time (growth)
Present value discounts a future sum back to the present (shrinkage)
Effect of interest rates
Higher interest rates lead to higher future values and lower present values (compounding, discounting)
Significance of lump sum cash flows
are single, one-time payments or receipts
Examples include investments (real estate purchase), loans (mortgage), and asset purchases or sales (business acquisition)
Lump sum cash flows serve as building blocks for more complex financial calculations
and are series of equal, periodic lump sum cash flows (monthly rent, annual dividends)
The timing of lump sum cash flows is crucial in determining their value
Cash flows occurring at different times must be adjusted for the time value of money to be comparable (net present value analysis)
Lump sum cash flows are used in various financial applications:
decisions compare the present value of future cash flows to the initial investment (project viability)
determines the periodic payments required to pay off a lump sum loan (car financing, student loans)
Retirement planning estimates the future value of current lump sum investments (401(k) contributions, IRA deposits)
Interest rates and investment evaluation
is the stated rate on financial instruments, not accounting for compounding or inflation
represents the true annual cost of borrowing or return on investment, considering compounding
Net present value (NPV) is used to evaluate investments by comparing the present value of all cash inflows to the present value of all cash outflows
is the discount rate that makes the NPV of all cash flows equal to zero
