# Time Value of Money Calculator

Calculate present value, future value, rate, or periods using the time value of money formula. Free TVM calculator for finance students and professionals.

## What this calculates

Solve any time value of money problem by choosing which variable to calculate. Enter three of the four TVM variables (present value, future value, rate, periods) and this calculator will find the missing one.

## Inputs

- **Solve For** — options: Future Value (FV), Present Value (PV), Interest Rate (r), Number of Periods (n) — Which variable do you want to calculate?
- **Present Value (PV)** ($) — min 0 — The current value or starting amount.
- **Future Value (FV)** ($) — min 0 — The amount you want or expect in the future.
- **Annual Interest Rate** (%) — min 0, max 100 — The annual rate of return or discount rate.
- **Number of Years** — min 0.5, max 100 — Number of years (or periods) for the calculation.
- **Compounding Frequency** — options: Annually, Semi-annually, Quarterly, Monthly, Daily — How often interest is compounded per year.

## Outputs

- **Result** — formatted as currency — The calculated value based on your selected variable.
- **Solving For** — formatted as text — The variable being calculated.
- **Total Interest / Growth** — formatted as currency — The difference between future value and present value.
- **Growth Multiple** — How many times the present value grows (FV / PV).

## Details

The time value of money is the foundation of all finance. The core principle: a dollar today is worth more than a dollar tomorrow because today's dollar can be invested and earn a return. The basic TVM formula is FV = PV x (1 + r)^n, where PV is present value, FV is future value, r is the interest rate per period, and n is the number of periods.

This calculator lets you solve for any of the four variables. Want to know what $10,000 invested at 5% for 10 years will be worth? Solve for FV. Have a $50,000 goal and want to know what to invest today? Solve for PV. Know the start and end values but want to find the implied return? Solve for rate.

Compounding frequency matters. The same 5% annual rate compounds differently depending on whether interest is added annually, quarterly, monthly, or daily. More frequent compounding produces a higher effective annual rate. A 5% rate compounded monthly has an effective annual rate of about 5.12%.

The TVM concept extends beyond investments. It applies to loan payments, lease valuations, retirement planning, business valuations, and any situation where money changes value over time.

## Frequently Asked Questions

**Q: What is the time value of money?**

A: The time value of money (TVM) is the principle that money available now is worth more than the same amount in the future due to its potential to earn returns. If you have $1,000 today and invest it at 5%, you will have $1,050 in a year. Therefore, $1,000 today is worth more than $1,000 received a year from now. This concept is the basis for interest rates, investment valuation, loan pricing, and virtually all financial decision-making.

**Q: How does compounding frequency affect the result?**

A: More frequent compounding produces slightly higher future values because interest starts earning interest sooner. At 5% annual interest, $10,000 grows to $16,289 after 10 years with annual compounding, $16,436 with monthly compounding, and $16,487 with daily compounding. The difference between annual and daily compounding at typical rates is usually small, but it becomes more significant with higher rates and longer time periods.

**Q: When would I solve for the interest rate?**

A: You would solve for the interest rate when you know the starting amount, ending amount, and time period, and want to find the implied return. Common examples: you bought a stock for $5,000 and it is now worth $8,000 after 4 years, what was your annual return? Or: an investment promises to double your money in 7 years, what rate is that? Solving for rate helps you compare different investments on an equal basis.

**Q: What is the difference between this and a compound interest calculator?**

A: A compound interest calculator is essentially a subset of TVM that solves only for future value. The time value of money calculator is more flexible because it lets you solve for any of the four variables: present value, future value, interest rate, or number of periods. It also does not include periodic contributions, which makes it the pure TVM formula. For scenarios with regular deposits or withdrawals, use a savings or annuity calculator instead.
