Marginal Revenue Vs. Marginal Cost In Construction

Every day Your Get Bombarded with ways to spend your hard earned money. Instead of saying no all the time here is a key strategy you can use to separate the good from the bad.

Organize them into three simple piles:

  1. Simple one-time investments

  2. Large purchases with a down payment and subsequent monthly payments

  3. Initial purchases followed by monthly or yearly maintenance payments

Apply three investment formulas

  1. Present value calculations

  2. Internal Rate Of Return (IIR)

  3. Discounted cash flows

  4. Opportunity costs

Here is how we do it for our clients

They provide three bits of information and we generate the report for them

  1. The cost (exact or rough estimate / whatever they have)

  2. How long they expect the tool / equipment will last (weeks / months /years)

  3. How much time they estimate it will save (minutes / hours / days)

From three bits of information and some custom reports we put into their QuickBooks For Contractors file we generate a one page summary report with support sub-documents as needed for them to make intelligent informed decisions.

Shown Below - Is a very simple formula to give you some insights on investing in a one-time office equipment upgrade. The principle applies just as easily with field tools and equipment using Office Labor Cost Calculations.

One-Time Investment:

Step 01 Initial Investment - Projected cost of the opportunity

Step 02 Alternate Use of Funds - Projected loss of interest or cost of borrowing initial investment

Step 03 Marginal Cost - Projected total Initial Investment plus Alternate Use Of Funds

Step 04 Marginal Revenue - Projected NEW revenue or savings from the opportunity

Step 05 ROI - Projected Return On Investment as a percentage

Step 06 Payback - Projected number of years for the opportunity to payback the Marginal Cost

Step 07 Annual Dividend - Projected NEW revenue or savings each year

Step 08 Life Span - Projected number of years the company will generate dividends

Step 09 Lifetime Value - Projected lifetime Value = (Annual Dividend X Life Span)

Step 10 Lifetime ROI - Projected lifetime Return On Investment as a percentage

Step 11 Construction Company - Annual profit as a percentage

Step 12 New Sales - Needed to generate same profit

Construction Bookkeeping Example: 

The Problem

  • Bookkeeper has one 19" RGB monitor on the desk

  • Hard to see numbers which causes eye strain

  • Bookkeeper is wasting 30 minutes a day due to poor equipment

Estimated Fully Burdened Costs To Hire A Bookkeeper In Your Office

Cost For 30 Minutes A Day Bookkeeper Time Wasted

The Solution

Invest In Dual 27" DVI monitors for your bookkeeper's computer at a rough cost of $600.00

  • Bookkeeper has two 27" DVI monitors on the desk

  • Numbers has no eye strain

  • Bookkeeper is not wasting time

Marginal Revenue Greater Than Marginal Cost For Investing In Dual Monitors For Your Bookkeeper Fast Easy Accounting

Increase Sales Or Reduce Costs - The two main drivers of profit. Best practices from successful construction companies are to do both. The key is a thorough analysis on a case-by-case basis for each opportunity.

The Example Shown Above - Should take about fifteen minutes if your QuickBooks setup is correct for construction and properly maintained so that it generates accurate useful reports.

If Your QuickBooks - Is not generating accurate reports contact us immediately because most business failures can be traced back to a lack of Key Performance Reports and bad bookkeeping. Download the free contractor bookkeeping checklist to find out for yourself if everything is on track.
