The Accumulation Ratio Calculator is designed to measure the growth of investments over a specified period. It calculates the future value of investments based on initial lump sum investments, periodic contributions, or a combination of both. By using this calculator, investors can project how their investments will accumulate, aiding in effective financial planning and investment strategy.
Formula of Accumulation Ratio Calculator
The Accumulation Ratio Calculator uses several formulas depending on the type of investment:
Future Value of a Single Lump Sum Investment
FV = PV * (1 + r)^n
Where:
- FV = Future Value
- PV = Present Value (initial investment)
- r = Periodic interest rate (annual interest rate divided by the number of compounding periods per year)
- n = Total number of compounding periods (number of years multiplied by the number of compounding periods per year)
Future Value of a Series of Equal Periodic Contributions (Ordinary Annuity)
FV = P * ((1 + r)^n - 1) / r
Where:
- P = Periodic payment
- r = Periodic interest rate
- n = Total number of payments
Future Value of a Series of Equal Periodic Contributions (Annuity Due)
FV = P * ((1 + r)^n - 1) / r * (1 + r)
Where:
- FV = Future Value
- P = Periodic payment
- r = Periodic interest rate
- n = Total number of payments
Combined Future Value of Initial Lump Sum Investment and Series of Periodic Contributions
FV_total = PV * (1 + r)^n + P * ((1 + r)^n - 1) / r
Where:
- FV_total = Combined Future Value
- PV = Present Value (initial investment)
- P = Periodic payment
- r = Periodic interest rate
- n = Total number of periods
These formulas help in understanding the future value of different types of investments.
Pre-calculated Values Table
To make it easier for you, here is a table of pre-calculated future values for various scenarios:
Present Value (PV) | Periodic Payment (P) | Periodic Interest Rate (r) | Total Periods (n) | Future Value (FV) |
---|---|---|---|---|
1000 | 0 | 0.05 | 10 | 1628.89 |
0 | 100 | 0.05 | 10 | 1257.79 |
1000 | 100 | 0.05 | 10 | 2886.68 |
2000 | 0 | 0.03 | 15 | 3124.58 |
0 | 200 | 0.03 | 15 | 4190.94 |
This table can be a quick reference for understanding the future value of your investments without needing to perform the calculations manually.
Example of Accumulation Ratio Calculator
Let's walk through some examples to illustrate how to use the Accumulation Ratio Calculator:
Example 1: Future Value of a Single Lump Sum Investment
Assume you invested $1,000 at an annual interest rate of 5%, compounded annually, for 10 years. To calculate the future value, use the formula:
FV = 1000 * (1 + 0.05)^10
FV = 1000 * 1.62889 = 1628.89
This means that your $1,000 investment will grow to $1,628.89 in 10 years.
Example 2: Future Value of a Series of Equal Periodic Contributions (Ordinary Annuity)
Assume you make periodic payments of $100 at an annual interest rate of 5%, compounded annually, for 10 years. To calculate the future value, use the formula:
FV = 100 * ((1 + 0.05)^10 - 1) / 0.05
FV = 100 * 12.5779 = 1257.79
This means that your periodic payments of $100 will accumulate to $1,257.79 in 10 years.
