How to Use the REG Calculator

Using the REG Calculator is simple and requires just three pieces of information. Here’s a quick guide:

  1. Enter Total Amount (Principal):
    • Input the amount of money you are investing, depositing, or lending.
    • Example: 10,000.
  2. Enter Rate (%):
    • Provide the annual interest rate percentage.
    • Example: 5.
  3. Enter Years (Time Period):
    • Specify how long the money will remain invested or borrowed.
    • Example: 3 years.
  4. Click on “Calculate”:
    • The tool will display the total interest earned and the final amount (principal + interest).
  5. Click on “Reset”:
    • Clears all inputs and reloads the calculator for a new calculation.

Practical Example

Let’s say you invest $20,000 at an annual rate of 6% for 5 years.

  • Step 1: Enter 20000 in the Total Amount field.
  • Step 2: Enter 6 in the Rate (%) field.
  • Step 3: Enter 5 in the Years field.
  • Step 4: Click Calculate.

Result:

  • Total Interest = (20,000 × 6 × 5) ÷ 100 = $6,000
  • Final Amount = 20,000 + 6,000 = $26,000

This gives you a clear estimate of what your investment will be worth at the end of the given period.
