Renovation Budget - How to Establish a Realistic Project

Embarking on a renovation project can’t be done without establishing a realistic budget from the get-go. How in the world are you supposed to budget the cost of all the work planned down to the last dime? There are two common methods used to calculate renovation costs: the square foot calculation method and the full-cost method. 

Which of these two methods is best for getting an accurate estimate? What are the advantages and disadvantages of each, and how do you choose the one that’s best suited to your project? Below are some tips to help you establish a detailed renovation budget meant to revamp your space to your liking.

How to Determine a Realistic Home Renovation Budget

Square Foot Calculation Method: Insufficient in Itself

This method gauges the total renovation cost based on the surface to renovate, according to the price of materials per square foot.

However, some experts have reservations about this method for very obvious reasons. Hence, as the square footage increases, the cost of materials decreases proportionally. As such, it’s difficult to gauge whether the amount calculated is realistic against the work at hand.

It seems this method may be insufficient in itself but is nevertheless useful to gauge potential project expenses. Indeed, this leaves little room to consider renovation project-specific peculiarities, as unforeseen circumstances may occur along the way.

Full-Cost Calculation Method

As for the full-cost method, it breakdowns the costs of each aspect of the project, such as:

• Materials

• Labour

• Necessary equipment

• And more

It also includes indirect costs, such as administrative fees. 

Only a qualified expert estimating the costs associated with residential renovation projects can consider all project ramifications to establish a realistic budget.

Beware of Project Contingencies Skewing Your Renovation Budget

Even if you manage to work out a budget that looks as good as possible against the amount to be paid out on completion of the work, it’s nevertheless imperative to budget for some leeway rather than be caught flat-footed by unforeseen circumstances.

To offset such an issue, budget roughly 15% of the total cost of your renovation project for that purpose.

Helpful Tips to Establish a Realistic Home Reno Budget

There are just too many parameters to consider when calculating a budget to allow you to establish an accurate estimate at a glance. Material price differences or the state of the area for renovation risks distorting your assessment.
