How Do I Estimate Interior Design Costs?

9 Aug, 2022

Whether you’re planning to start a side business or simply want to renovate an existing space, estimating costs for interior design projects can be a real headache. But don’t worry! We’re going to walk through my easy-to-use, step-by-step method that will ensure you’ll get a realistic estimate that you can actually afford.

What Is The Average Interior Design Fee?

A design fee functions as a service charge for the time and effort the interior designer invested in planning and designing the arrangement of your home. It can be in the form of a pre-set rate, an hourly rate, a flat rate, or a percentage of the project. Having said that, if the company requests a deposit of more than 20% to 30%, requests payment in cash, or requests that you make checks payable to someone other than the interior design firm you are hiring, this may be a clue that they are phony.

The design expenses will also be impacted by the floor area, labor, materials, and other incidentals. For either a HDB or a condominium, general design fees would range from about $1,500 to $6,000. You could wish to request free interior design consultations so you can assess their skills before choosing to hire them. The cost of Singapore home design varies depending on the company. The charge increases with the level of experience of the designers.

How to Calculate Cost of Interior Design?

Calculating your interior design budget might be difficult. There are various methods to determine your interior design cost depending on your designer.

Flat Fee

The flat or set cost, which is currently the most common type of interior design price, can also be the most difficult to determine. When you provide your charge, you frequently don’t know if the customer will need a lot of extra guidance and be uncooperative, prolonging the project’s scope and timetable, or if they will be cogent and everything will proceed as planned. You can always include a provision to your contract that guards against such unforeseen events.

If you’ve been in business for a while and can predict what a job will require, choosing the appropriate fixed or flat price is frequently easier. In order to safeguard yourself from unanticipated overruns, you might base it on hours and then add a 15% or higher buffer. The flat rate is charged according to the factors:

  • Budget
  • Experience
  • Time taken
  • Per sqft

Hourly Cost

Each minute they spend will be deducted from your account. Emails, calls, problems, ordering, logistics, shopping, installation, designing, driving, returning sample, etc. are all included in this. Be aware that this choice is not the least expensive one because the project might not be finished on schedule. 

You would be required to pay $6,750, for instance, if they worked on your project for a total of 45 hours at a rate of $150 per hour.

Project Cost Percentage

The percentage of the project cost method should be used to determine interior design fees. From an invoicing standpoint, it is really straightforward and involves total transparency, something that many designers find difficult to do. Give the client a project estimate that takes into account all project components, such as furniture, fixtures, finishes, installation, contractors, and more. If you are worried that they would disassemble it, you can set a minimum project value to guarantee you receive a minimum payment. The percentage you decide on is added on top of the project costs; interior design fees typically range from 30% to 45%.

Square Footage Cost

This approach is incredibly straightforward and effective when remodeling a large room, such as a great room, master bedroom, or enormous kitchen. If you were taking on a 15 by 20-foot room, your cost would range from $3000 to $5100 depending on whether you charged $10 or $17 per square foot. 

If this is a renovation or remodel, you might choose to utilize this only for Singapore home design services and add a percentage to cover all furniture that were chosen and acquired. You might also want to include a percentage to fund contractor management.

Retail Fee

similar to markup fee, but slightly different. You will pay the retail price while your designer will pay the net price of the goods. The cost will change based on the discount you obtain as well. 

For instance, your designer’s purchases from you cost $9,000. Due to a 40% designer discount, their final price was $5,400. You will be paying $3,600 because it is the retail price.

Combination Method

It is uncommon for a designer to be paid just on an hourly basis; instead, most hourly rates are combined with a percentage of sales that can be anywhere between 25 and 35 percent above cost. Another option is for a designer to forgo adding a markup and instead split trade reductions with their client. 

Your ability to command a high fee is less influenced by your skill and expertise than it is by your confidence, positioning, and capacity for gaining and retaining trust. I’ve dealt with both established designers who charge what a new designer would charge and emerging designers who are prepared to enter the market at a more established rate.
