Using the Project Cost & Timeline Calculator

This guide will walk you through the process of using the Project Cost & Timeline Calculator to estimate the cost and timeline for your project. Follow each step carefully to ensure accurate results.

Step 1: Input Project Details

First, provide the basic information about your project in the input fields provided.

  • Project Type: Select the type of project you are developing. Options include:

    • Simple Website
    • E-commerce Site
    • Custom Web Application
    • Enterprise Solution

    Your selection impacts the project scope and cost multiplier.

  • Number of Pages/Features: Enter the total number of pages or features in your project. This value must be between 1 and 100.
  • Hourly Rate: Specify the hourly rate in USD that will be charged for the work. The rate should be between $10 and $500 per hour.
  • Project Start Date: Choose the start date for your project. Ensure the date falls between January 1, 2024, and December 31, 2026.
  • Project Complexity: Indicate the complexity level of your project. Options include:

    • Simple
    • Moderate
    • Complex
    • Very Complex

    Complexity levels influence the time and effort required to complete your project.

Step 2: Calculating Estimates

Once all input fields are filled out, the calculator will compute several key estimates for your project.

  • Estimated Hours: The total number of hours required to complete your project, calculated using the formula:
    numberOfPages * 8 * projectType * complexityFactor. This figure is displayed with one decimal place and suffixed with “hours”.
  • Total Project Cost: The estimated cost of completing the project, calculated with the formula:
    estimatedHours * hourlyRate. The amount is shown in USD, with two decimal places.
  • Estimated Completion Date: The forecasted date of project completion, derived by adding the project timeline to the start date, using the formula:
    addYears(startDate, estimatedHours / (8 * 20 * 12)). The date is formatted as YYYY-MM-DD.
  • Cost per Page/Feature: The average cost per page or feature, determined by dividing the total project cost by the number of pages:
    totalCost / numberOfPages. This cost is displayed in USD with two decimal places.
  • Project Duration (Days): The total number of working days needed to complete the project, calculated as:
    ceil(estimatedHours / 8). The result is presented as a whole number with a “working days” suffix.

Conclusion

By following these steps and inputting accurate information into the Project Cost & Timeline Calculator, you will obtain detailed estimates of the time and cost involved in executing your project. Use these insights to effectively plan and allocate resources for successful project completion.
