Interest Rate on $1 Table Creator
Create a printable interest rate table to lookup the interest rate required to grow $1 to a future value amount.
Interest Rate Table (Percentage)
How to Use This Table
This table shows the interest rate (in percentage) required to grow $1 to various future values over different time periods.
Example: You want to invest $10,000 and triple your investment over time. How many years will it take for you to triple your investment and at what interest rate?
1. Look for FV = $3.00 in the table columns.
2. In the $3.00 column, you can lookup interest rates and the corresponding number of periods (n) it will take to triple your investment.
3. For example, if you find that at n=10 periods, the interest rate is 11.61%, this means that at an 11.61% annual interest rate, your $10,000 investment will grow to $30,000 in 10 years.
Formula used: I = (FV^(1/n) – 1) * 100, where FV is the future value and n is the number of periods.
Interest Rate on $1 Table Creator
An Interest Rate on $1 Table lets you quickly find the rate of return required for $1 to grow to a chosen future value (FV) over a set number of time periods. This is a practical tool for investment planning and understanding compound growth.
Formula for Future Value
The basic future value formula is:
FV = PV (1 + i)^n
Where:
- FV = future value
- PV = present value (starting amount)
- i = interest rate per period (in decimal form)
- n = number of periods
To calculate the interest rate (i), solve for i:
i = (FV / PV)^(1/n) - 1
Applying to a $1 Investment
If the present value (PV) is $1, the formula becomes:
i = (FV / 1)^(1/n) - 1
To express this as a percentage rate (I):
I = (FV^(1/n) - 1) * 100
Where:
- I = interest rate in percentage form
- FV = chosen future value
- n = number of periods
Example: Tripling an Investment
Say you want to invest $10,000 and triple it. Since the table is based on $1, you set FV = 3.
- Go to the FV = 3 column in the table.
- Look down the rows for different n values (number of periods).
- The table gives the corresponding interest rates needed.
This shows how many years and what rate of return are required to triple your money.
This table helps you quickly reference rates across compounding intervals — explore more tools to calculate them precisely:
- Compute your rate directly with the Nominal Interest Rate Calculator.
- Convert to periodic or annual forms with the Periodic Interest Rate Calculator and Effective Annual Rate Calculator.
- Evaluate compound growth in the Compound Interest Calculator or Periodic Compound Interest Calculator.
Building the Interest Rate on $1 Table
To make the table:
- Future Values (columns): Start at FV = 2.0 and increase by 0.5 (2.0, 2.5, 3.0, 3.5, etc.).
- Periods (rows): Start with n = 10 and increase by 1 for at least 20 rows.
- Fill in Interest Rates: Use the formula:
I = (FV^(1/n) - 1) * 100
This creates a simple lookup table that shows the interest rate required for $1 to grow to any chosen FV over n periods.
