Furnishing a home is exciting because it’s what turns a house into a reflection of you. The pieces you choose often stay with you through various moves and seasons of life until you are ready to replace them. Whether you're starting from scratch or thoughtfully layering new pieces into an existing space, how much you invest will depend on your lifestyle and long-term vision.
Some clients value high-quality, long-lasting furnishings that are timeless and built to last. Others take a more budget-conscious approach, focusing on flexible options that allow for quicker updates and more changes down the line. Most projects land somewhere in the middle: a balanced mix of investment pieces and smart savings that work together to create a cohesive, comfortable home.
No matter your approach, the key is to understand what matters the most to you—whether that’s durability and customization or flexibility and affordability—and let those values guide how your budget is allocated.
The cost of furnishing a home often adds up faster than anticipated, leaving homeowners surprised by how quickly their budget is exceeded. To plan more effectively, it’s important to understand two hidden key factors that often times drive up the overall cost: the silent overspending of piecemeal decorating, and the importance of the 60-25-15 budgeting rule, a budgeting approach we created to guide our clients.
When you've slowly added pieces to your home over time, spreading purchases across months or years, it's easy to lose sight of the total investment. Each individual purchase feels manageable, but the cumulative cost often exceeds what you would have spent on a complete room design from the outset.
Complete room design, where everything is planned and purchased together, provides full cost transparency upfront. While seeing the total number can feel overwhelming initially, this approach actually delivers better value through coordinated purchasing, avoiding costly mistakes, and ensuring every element works together. If you're considering working with a designer to achieve a professionally completed space, the overall results and long-term savings will far outweigh the hidden costs and limitations of piecemeal decorating.
One of the biggest budgeting mistakes homeowners make is assuming their "furniture budget" equals their "room budget." In reality, furniture typically accounts for only about 60% of a complete room transformation. The remaining 40% covers essential finishing pieces, such as rugs, lighting, window treatments, art, and accessories, plus necessary costs, including tax, shipping, and installation.
These finishing touches aren't optional extras—they're what transform a collection of furniture into a cohesive, functional, and inviting room. Yet they're frequently overlooked in initial planning, leading to budget overruns and the frustrating feeling of having spent more than intended. By using the 60-25-15 rule and factoring in all elements from the start, you'll have a realistic understanding of what it truly costs to complete your space.
Understanding these key cost drivers and how they interact with each other provides a more realistic view of what it takes to fully furnish your home. Let’s take a closer look at each one to help you estimate your budget with confidence.
If you’ve only considered the cost of furniture when thinking about your home furnishing budget, and use that as the sole framework for your interior design project, it can significantly affect both the scope of what’s achievable and the final investment required to complete the space fully and successfully.
For example, if you communicate to an interior designer that your total project budget is $50,000, that amount will typically be allocated across the three key categories as follows:
However, if that same $50,000 was intended solely for furniture, without accounting for the additional costs of accessories, tax, and shipping, the actual total investment would be significantly higher:
This shift in how you define your budget is a common source of confusion. Without a clear understanding of what’s included in the total budget, it’s easy to underestimate the true cost of completing a space. That’s why clarity and upfront planning are essential for setting accurate expectations and avoiding surprises later in the project.
Accessories are often one of the most underestimated elements in a design project, both in terms of quantity and cost. This common oversight can lead to rooms that feel unfinished and can create frustration when the final budget exceeds initial expectations.
A helpful starting point is to assess your current space: count the number of accessories you already have, and ask yourself whether the room feels visually complete or lacking in warmth, personality, or detail.
In most cases, completing a smaller living room requires a minimum of 30 accessories to achieve a layered, finished look. Depending on the size of the room and the presence of built-ins, shelving, or open surfaces, that number can easily double or even triple.
Accessories such as decorative objects, artwork, area rugs, lighting, books, and greenery all play an important role in creating balance, texture, and visual interest. Transforming it from simply furnished to intentionally finished.
Below is a foundational list of 30 accessories needed to complete a living room.
This list of 30 accessories illustrates why accessories can represent a significant portion of your overall budget.
If you’re planning a room refresh and want a quick estimate for the cost of accessories, consider the average price points for the 30 items:
This total aligns closely with the accessory allocation from our first example based on a $30,000 furniture budget. With this example, you can quickly see how these costs can add up, and why it’s essential to include accessories in your initial furnishing budget strategy, and not consider it as an afterthought.
A well-rounded furnishing budget strategy should always account for the added costs of tax and shipping, expenses that are often underestimated or overlooked. With many pieces being purchased online or through trade sources, it’s wise to allocate at least 15% of your total budget for these charges. Typically, tax and shipping are each around 7–8%, so a 15% buffer helps cover both, including any variations based on item size, weight, or delivery complexity.
If you're working with an interior designer, it’s recommended to set aside closer to 20%. This higher estimate reflects the elevated level of service you’ll receive. Designers often manage the full logistics of sourcing, ordering, receiving, and inspecting items, ensuring that everything arrives in perfect condition and is installed seamlessly. This “white glove” approach is designed to give you a streamlined, stress-free experience, with no surprises on delivery day.
Furnishing a home involves more than selecting beautiful pieces; it requires a thoughtful, well-structured budget to avoid surprises and ensure a cohesive, finished space. A clear and realistic furnishing budget strategy is the foundation of a successful design project. When you understand what’s truly involved and plan accordingly, you set yourself up for a smoother experience and a beautifully completed space.
