The smart way to plan your renovation budget


Is figuring out the cost of your dream renovation keeping you up at night? You're not alone - and you’re not wrong to be concerned.


One of the biggest mistakes homeowners make is jumping into a renovation without a clear, realistic budget. That’s why I’ve created a simple, straightforward guide to help you plan with confidence - whether you're redesigning a kitchen, transforming a primary suite, or updating your entire home, a well-planned budget is essential to achieving timeless results without costly surprises. Inside this renovation budget planner, I'll walk you step-by-step through the same process I use with my private clients to build clear, realistic budgets, before any work begins.


One of the biggest challenges I see? Most homeowners have absolutely no idea what kind of investment they're stepping into. It could be $30,000. It could be $300,000. And without a starting point, it’s nearly impossible to make informed decisions or move forward comfortably.


Ready to budget like a pro?


Step 1: Envision Your Ideal Space

Okay, so maybe you’re not a designer, builder, or architect - and no one’s asking you to sketch blueprints on a cocktail napkin. But let’s be honest: you probably already have a very clear idea of what you want.


Whether it’s that dreamy chef’s kitchen you’ve saved 47 times on Pinterest, a spa-like bathroom escape, or a closet that would make a fashion editor weep, this is the time to start imagining your ideal space in full detail.


Don’t worry about the technical stuff yet. Just focus on the feeling, the function, and the features you can’t live without. That vision will be the foundation of every smart decision (and dollar) that follows.


Step 2: Curate the vision


Now it’s time to start collecting visual inspiration - the fun part!


Head to Pinterest (my personal favorite for this), Houzz, or wherever you like to gather ideas, and start saving images that reflect what you want in your future space. But here’s the key: this isn’t about hoarding—it’s about curating.


If you’ve been pinning obsessively for four years and have a board with 500 kitchen ideas... this is your moment to edit. Create a new board, section, or folder with only your favorites - the images that truly capture your wishlist.


As you go, jot down a quick note about what you love in each photo. (Pinterest and Houzz both let you add comments directly on your saves.) You’ll thank yourself later when you’re trying to explain to your designer why that cabinet color or those pendant lights just feel right.


Trust me - this step will save you so many headaches down the road.

Step 3: Itemize your materials and merchandise: aka Where Dream Meets Reality


Now we’re going to start translating your design vision into real numbers.


With your inspiration images at the ready, mentally walk through the space and begin listing every visible element you’ll need to bring that room to life. Start at the door and move around the perimeter - no detail is too small.


Take a primary bathroom, for example. You might include:

  • A custom vanity

  • Cabinet hardware

  • Stone countertops

  • Two sinks + two faucets

  • Medicine cabinets

  • Three sconces

  • A freestanding tub + tub filler

  • A heated towel rack

  • Floor tile, wall tile, and shower tile

  • Accessories like towels, bathmats, a soap pump, artwork...


And don’t forget to include the features typically handled by your contractor or builder—things like heated floors, a steam shower, recessed lighting, ceiling speakers, or specialty ventilation. These items may not show up on your Pinterest board, but they’re essential to pricing the full picture.


Start with pen and paper if it’s easier, but I highly recommend moving your list into a spreadsheet - Google Sheets or Excel - so you can stay organized and eventually attach pricing.


You’re essentially creating the first draft of your design specifications - and this list will become the foundation for both your budget and your conversations with vendors and trades as you move forward.


If you’re the type who loves a well-organized list (or would rather not start from a blank page), I’ve also created a free resource to help. My Design & Renovation Cost Estimator includes printable, editable product lists for every major room, so you can jump right into Step 4 with a clear, organized framework.


Step 4: Quick Estimates, Smart Strategy: don’t overthink it—just get in the zone


Well done! You’ve defined your vision and created a detailed list of all the elements in your space. Now it’s time to start assigning some ballpark numbers to those items.


A couple sitting together with a laptop, spreadsheet, and a few samples in front of them, smiling as the numbers come together and they see their plan start to take shape.

Yes, this step will take a little time and research - but I promise, this is not a PhD thesis, and you don’t need to channel Sherlock Holmes. You’re not trying to build a final quote - you’re simply getting a sense of scale so you can make smart decisions moving forward.


What kind of transformation are you planning? Before diving in, take a moment to consider the overall scope and quality level you’re aiming for. Is this project:


  • Value-driven and just looking for a refresh?

  • Mid-range with a few standout features?

  • Or creating a truly elevated space that you’ll love for decades?


Let your answers guide your estimates. The level of finish you’re envisioning should be reflected in the prices you use - at least approximately.


How to research fixtures, furnishings, and accessories


Head to Google, Houzz, Perigold, or manufacturer and retailer websites. Don’t get sucked into hunting for THE perfect faucet, or attempting to recreate your Pinterest inspiration space - that will come later as you collaborate with your design professional!


Your only objective here is to find items that look similar in style and quality to what you want, then plug those placeholder prices into your spreadsheet.

A few quick notes:

  • The internet has become saturated with low-cost junk, and that’s often what pops up first.

  • That $150 faucet? Likely plastic, will leak in a year, and won’t include all the parts needed for installation.

  • As in all things, you get what you pay for.

  • Keep this process quick, keep it easy, and don’t get caught in the weeds.


And remember - this process is not about nailing down exact numbers. It’s about getting into the right financial territory so you can move forward with confidence, reduce anxiety, and enjoy the process of bringing your dream space to life.


How to estimate material costs


For materials like flooring, tile, countertops, and wallcoverings, you’ll need to make some educated guesses.


Let’s say you’re planning new hardwood floors - estimate the square footage, find an approximate price point based on your quality level (value, mid-range, or luxury), and do the math. Don’t worry if you don’t have final measurements because the space hasn’t been designed yet. For example, if your dream is to expand the bath into the unused guest room behind it, total the square footage for both spaces and use that for your rough number. The same would apply for enlarging the shower, or adding an addition.


Ballpark is better than blank.


Accounting for the invisible


Once you’ve estimated your merchandise and materials, you’ll have a subtotal - but there’s more to consider. This is where many budgets go sideways.


There are elements you won’t see in Pinterest photos or even have the ability to search for. For example:

  • Rough-in valves for plumbing

  • Heated floors

  • Specialty lighting and control systems

  • Custom fabrics, cushions or window treatments

  • Specialty hardware, brackets, and trim kits


…basically all the invisible things that make the visible things work beautifully - and can quietly drive up costs if unaccounted for.


To account for these unseen or specialty costs, I recommend adding 10–30% to your subtotal depending on your project’s level of customization and your budget flexibility. Luxury projects tend to include more upgrades and specialty items, while renovations with fixed budgets may want to pad more aggressively to avoid surprises.

Final thoughts before we move on


Don’t overthink this process. You’re not building out the final budget - you’re creating a smart starting point. As we work together, I (or your design professional) will help refine your numbers for accuracy, ensure your pricing aligns with your quality expectations, and fill in any gaps to make sure you’re not blindsided by unexpected costs.


But for now? You’ve done the heavy lifting. And look at you - already making smarter decisions than half of HGTV.


Which brings us to Step 5...


Step 5: Pricing the Design & Execution


So far, we’ve focused on estimating the cost of the materials and fixtures that will shape your finished space. But a beautiful design doesn’t install itself—and pricing your project accurately means accounting for the professionals who will bring it all to life.


This includes the creative expertise that ensures your space is cohesive, functional, and tailored to your lifestyle, as well as the behind-the-scenes coordination, skilled trades, and craftsmanship required to execute it flawlessly.


The design and execution phase will typically include:

  • Interior design fees

  • Architectural or drafting services (if needed)

  • Project management or general contracting

  • Labor for all trades (demo, build, install, electrical, plumbing, etc.)

  • Delivery, receiving, and installation


Depending on the complexity of your project, this phase may very well represent the majority of your overall investment.


This is the point where you’ll want to bring your designer on board—because finalizing the design is what unlocks the rest of the puzzle. Once your vision is refined, your materials and finishes are selected, and your space is fully planned, your designer can begin coordinating with the necessary professionals to bring it all to life.

From architects and general contractors to cabinetmakers, tile installers, and specialty trades, your designer likely has trusted, long-standing relationships with exactly the people your project will require. That kind of network is a major advantage - saving you time, guesswork, and the trial-and-error of hiring on your own.


Even more importantly, your designer becomes the point person who ensures everyone is aligned, every detail is accounted for, and nothing gets lost in translation.


This phase is where things can either become chaotic - or beautifully choreographed. And that orchestration? It starts with a complete, professionally-led design plan.


How to estimate the cost of design and execution


The cost of design, labor, and project management doesn’t scale perfectly with the price of your merchandise. In fact, it often requires just as much time - and sometimes more - to plan and install a well-executed space with budget-conscious materials as it does with high-end ones.


A few things to keep in mind:

  • Installation labor is based on complexity and scope, not brand labels. A faucet is a faucet, whether it cost $200 or $2,200 - it still requires a licensed plumber, time, and coordination.

  • Design time doesn’t shrink just because you’re spending less. In fact, working within a tight budget often requires more strategic planning, more sourcing, and more creative problem-solving. Designing on a tighter budget can sometimes feel like trying to create a Michelin-star meal on a grocery store budget - possible, but it takes skill, patience, and a few secret ingredients.

  • Project management is essential at every level. Whether your renovation is modest or luxurious, someone needs to oversee timelines, deliveries, trade schedules, and quality control.


With that in mind, here’s a good general rule to finish out your budget planning:

  • If you’re working on a light or value-conscious remodel, plan to add as much as - or more than - your merchandise budget to cover design, labor, and project oversight.

  • For mid-range to luxury projects, design and execution can represent 40–60% of your total investment once all elements are accounted for.


Still feeling unsure where to land? Add a buffer. It’s far better to be pleasantly surprised than stretched thin halfway through your project.


Congratulations!


You’ve just done something most homeowners never do: you’ve taken the time to thoughtfully explore your vision and determine what it will realistically require to bring your project to life.


By taking time to thoughtfully explore your vision and investment, you’ve set yourself up for a smoother, more enjoyable remodeling experience. You’re not just hoping it will work - you’re making informed, confident decisions before the first hammer swings.


When you’re ready to turn your vision into a fully realized plan - with expert design, trusted professionals, and calm, coordinated execution - I’d be honored to guide you through every step.
