Estimating Actual Project Costs

To use the MacNail construction accounting software to make an estimate of the final project cost:

1. Update the job cost sheet with the most recent numbers available (see previous section).
2. Type your estimate of the percentage completed for each construction division under the pct done column. If the item is about half done, type in 50. If the item is completely finished, type in 100. If the item has not been started yet, leave it blank.completion percentage
3. Notice that for each item, a predicted cost is calculated.
4. The hi low column tells you where it looks like the item will end up, relative to the original estimate.
5. The net balance column tells you how much is left of the original estimate for that item. If the number is negative, the budget has already been overspent.
6. The pct spent column tells you the percentage of the original budget that has been spent. If it is over 100%, you are already over budget for that item.
7. The labor hours column at far right stores actual labor hours for each item, based on the Labor Logs. It will be used by MacNail Customizing to update labor unit prices, improving your future estimates based on the results of your current projects.

NOTE-- In 2000, MacNail was replaced by Goldenseal construction accounting software. Goldenseal is an integrated program that includes general accounting, job costing, payroll and project billing, plus estimating and other features. It provides job costing similar to MacNail, with "estimated vs actual" reports and other job costing info.
