Finance Calculator (Time Value of Money - TVM) Guide
The Finance Calculator is a tool used to solve problems related to the Time Value of Money (TVM), which explains how money changes value over time due to interest, inflation, and investment opportunities.
In simple terms, money today is worth more than the same money in the future because it can be invested and earn returns.
1. Time Value of Money (TVM)
The Time Value of Money concept is based on the idea that receiving money today is better than receiving it later.
- Money today can be invested
- It can earn interest
- It loses value over time due to inflation
Basic Example
If you have $100 today and the interest rate is 10% per year:
| Year | Amount | Explanation |
|---|---|---|
| 0 | $100 | Present Value (PV) |
| 1 | $110 | After 10% interest |
| 2 | $121 | Compound growth |
2. Key Components of Finance Calculator
- PV (Present Value): Current value of money
- FV (Future Value): Value of money in future
- I/Y (Interest Rate): Rate of return per year
- N (Number of Periods): Time duration
- PMT (Payment): Regular payments (monthly/yearly)
Formula Example
Future Value formula:
FV = PV × (1 + r)n
Where:
- PV = Present Value
- r = Interest Rate
- n = Number of periods
3. Compounding Example
If $500 is invested at 8% annual interest for 3 years:
| Year | Calculation | Result |
|---|---|---|
| 1 | 500 × 1.08 | 540 |
| 2 | 540 × 1.08 | 583.2 |
| 3 | 583.2 × 1.08 | 629.86 |
4. PMT (Periodic Payment)
PMT refers to regular payments made or received at fixed intervals such as monthly savings, rent, or loan payments.
- Monthly salary deposits
- Loan repayments
- Rental income
Example
If you receive $1000 monthly rent for 12 months:
Total = 1000 × 12 = $12,000
5. Real-Life Applications
- Bank savings and fixed deposits
- Home and car loans
- Investment planning
- Retirement planning
