Get a quick estimate of your interior design budget.
Our Interior Budget Calculator helps you estimate and organise the costs of your home interior design project. Whether you are decorating a bedroom, updating your living room, planning a modular kitchen or renovating your entire home, creating a budget helps you understand your expected expenses before work begins. Use the calculator above to plan your project according to your requirements and available budget.
Start by deciding which rooms you want to design or renovate. List the main requirements for each space, including furniture, storage, lighting, paint, flooring and decorative accessories. Estimate the cost of each item and add the amounts together to understand your expected project expenses.
Compare different materials and product options before making purchases. Prioritise essential work first, such as electrical improvements, storage and major furniture. Decorative items can be selected later if your budget is limited.
A home interior project may include several types of expenses. The following table lists common categories to consider when preparing your budget.
| Category | Examples |
|---|---|
| Furniture | Beds, sofas, tables and chairs |
| Storage | Wardrobes, cabinets and shelves |
| Finishes | Paint, flooring and wall finishes |
| Lighting | Ceiling lights and task lighting |
| Labour | Installation and professional services |
Interior design costs depend on the size of your home, the number of rooms, the materials you choose and the complexity of the work. Custom furniture and modular storage may cost more than standard ready-made options. The location of your property, contractor charges, delivery and installation can also affect the final amount.
Prices can vary between suppliers and change over time, so request current quotations before finalising your budget. It is also sensible to keep a contingency amount for unexpected repairs, additional materials or changes during installation. The calculator provides an estimate, not a guaranteed quotation.
Set a maximum spending limit before selecting materials or furniture. Measure your rooms carefully, compare quotations and focus on the items that matter most to your daily comfort. Choose finishes that suit your lifestyle and are easy to maintain. Keeping a written list of estimated and actual expenses can help you identify overspending early and make better decisions.
