Home builders and remodelers usually allocate between 5% and 10% of a project budget for a construction contingency. This amount creates enough breathing room for unexpected costs. Anyone tracking estimates and costs manually will calculate a contingency percentage on top of all costs before profit margins are applied.
It provides a safety net for unexpected expenses and ensures the project stays on track, both in terms of budget and timeline. The recommended percentage for a contingency fund is between 5-10% of the total budget, but this may vary depending on project complexity and past experiences.
This contingency is normally calculated as a percentage. If the phase is 100 days of effort, contingency at 20% would be another 20 days. As the project progresses, the level of risk reduces as the requirements and issues become known, so the percentage will be reduced.
The Architect's Handbook of Professional Practice clarifies a contingency allowance as the amount, or percentage, included in the project budget to cover unpredictable changes in the work or items of work. It serves three core purposes: To account for errors and omissions in the construction documents.

The average contingency rate falls between 20-40%, with most lawyers charging around 33% to 35% of the total amount recovered in a case. The exact percentage can vary depending on the complexity of the case, the lawyer's experience, and the stage at which the case is resolved.
The contingency allowance is the time allocated during planning for unscheduled events. Technical and personal disruptions result in changes in the indirect production costs. The contingency allowance is calculated in special contingency time studies, the results of which yield rates for indirect production costs.
The most basic way to calculate a contingency reserve is to add a fixed percentage to the total project budget, known as the Flat Rate method. Alternatively, if different percentages are applied to unique budget line items, this would be called a Mixed Rate method to establish the reserve.
Typically, most construction projects use a contingency rate of 5% to 10% from the total project budget. This is typically enough to cover any unexpected costs that may arise throughout the project.
