This free e-Griffin Construction Cost Calculator will provide you with a Professional Preliminary Estimate Estimate for your project in just a few minutes.

It uses approximate quantities which are calculated for you from the information you provide and prices from its database which is regularly updated. The input form will take a few minutes to complete but the more data you enter the more accurate your estimate will be. Don't worry if you don't have all the information, the calculator will fill in any missing data with averages from its database. You can always re-enter your actual figures when you know them and the calculator will adjust your building cost estimate.

For those of you in a hurry or just want a very basic estimate there is also a Ball Park Estimate available.

Both calculators are free to use.

To continue all you need to do is read and accept our terms and conditions by ticking the terms and conditions box below; then choose which Estimate you would like to use.

I have read, and accept, the Terms and Conditions relating to the use of this system.


After completing the input form, your estimate will be generated and available to print or download.

If you want another estimate just click on' Return To Input' and alter your data and an amended estimate will be calculated instantly.
