Frequently Asked Questions

What is a contingency buffer?

A contingency buffer is a percentage added to your project cost to account for unexpected expenses, scope changes, or delays. Industry standard is typically 10-20% depending on project complexity and risk level.

How is the profit margin calculated?

The profit margin is applied as a markup on top of the subtotal plus contingency. For example, if your costs after contingency are $5,000 and you set a 15% margin, the markup adds $750 to your total.

When should I include tax?

Include tax if your jurisdiction requires you to charge sales tax or VAT on services. Set the tax rate to 0% if taxes are not applicable to your situation.

Can I save my estimates?

Currently, estimates are calculated in real time within your browser. You can take a screenshot or copy the values for your records. All data stays in your browser and is not stored on any server.

Privacy Note: Your project data never leaves your device, ensuring complete confidentiality of your estimates.

How do I choose the right hourly rate?

Consider your experience level, market rates for your skill set, location, and the complexity of the project. Research industry benchmarks and adjust based on the value you bring to the client.
