How to Use the Substitution Calculator

This guide will walk you through using the Substitution Calculator to determine if replacing an asset is financially beneficial. Follow the step-by-step instructions below to input the necessary data and receive an in-depth analysis of your asset’s value.

Step 1: Enter the Current Value

Start by filling in the “Current Value ($)” field. Enter the current market value of the asset you are assessing. Make sure your entry is a non-negative number, as this is a required field.

Step 2: Input the Depreciation Rate

Next, locate the “Annual Depreciation Rate (%)” field. Input the yearly depreciation rate in percentage form. This field requires a value between 0 and 100, and it must be a positive number. You can use increments of 0.1 for precision.

Step 3: Specify the Asset Age

In the “Asset Age (Years)” field, enter how many years the asset has been in service. This value should be non-negative and can be entered in 0.5-year increments to account for partial year usage.

Step 4: Provide the Replacement Cost

Find the “Replacement Cost ($)” input field and enter the cost to replace the asset with a similar new one. Ensure your entry is non-negative, as this detail is crucial for the final assessment.

Step 5: Detail the Maintenance Cost

Finally, complete the “Annual Maintenance Cost ($)” field with the costs associated with maintaining the asset per year. This field must also contain a non-negative value.

Step 6: Review the Results

  • Once all fields are completed, the calculator will provide results in the following categories:
  • Depreciated Value: This is the current value of the asset after accounting for annual depreciation over its lifetime.
  • Total Maintenance Cost: The sum of maintenance expenses over the asset’s age.
  • Net Replacement Benefit: Calculated as the difference between the depreciated value and the replacement cost, adjusted by the total maintenance cost.
  • Replacement Advised: This field will indicate whether replacing the asset is financially advisable. A result of ‘Yes’ suggests replacement may be beneficial, while ‘No’ suggests retaining the asset is preferable.
