When calculating your roofing contract price, you want a formula favorable to your profit margins. However, what construction contract should you go for if you are confident about keeping below estimated costs and within the given time schedule?

Cost-plus variable fee contracts offer incentives either on top of a fixed fee or as a percentage of the cost. This can afford you a handsome bonus in your pocket. In this guide, we walk you through how you can capitalize on a cost-plus variable fee contract.

How to set your roofing contractor price Roofing Construction Projects

Cost-plus variable fee contracts have a simple premise:

  1. Do the work at a fixed fee and keep costs below estimated budget costs. Share the cost savings with the project owner based on a percentage ratio (reward). Exceed estimated budget costs, deduct overruns from your fixed fee (penalty). This is the cost plus fixed fee and award variant of the cost plus variable fee contract.
  2. Do the work to meet a target cost and earn a target fee, with a minimum and maximum deviation from the target cost and target fee. If you complete the project below target costs, share cost savings with the project owner. If you exceed maximum allowable costs, there is a decrease in the target fee paid to the contractor. A pre-defined slider-rule formula is used to determine costs. This is the cost-plus incentive fee variant of the cost plus variable fee contract.

As a competent contractor with a solid track record of completing projects on schedule and within budget, you can, therefore, stand to earn a neat bonus. Moreover, the general rule for the cost plus award fee contract is that you will share the cost savings fifty/fifty with the project owner. For every dollar you save on the roof construction costs, you keep 50 cents.

As a rule, the percentage for sharing the penalty/ bonus is usually 50/50. Generally speaking, the law does not recognize a penalty-only contract.

What are the drawbacks?

When you set your roofing contractor price, if your budget estimates are off, or if for reasons beyond your control you cannot complete the project on schedule. Thereafter, you will most likely receive a penalty and lose money.

What should you consider when negotiating a roofing contract price?

A cost-plus variable contract can widen your profit margin on your roofing contract price. However, if materials and labor costs are volatile in an unstable supply market, you may wish to consider another contract type. Furthermore, since your margins are dependent on cost estimates, a sudden increase in materials costs before construction is completed, may put you above budget and attract penalties,
