Renovation Budget Allocator by Percentage
Enter one total renovation budget and see how many dollars land in each category — kitchen, bath, flooring, labor and everything else — using splits you control.
Calculator
On a $60,000.00 budget, kitchen gets $15,000.00 and bath $9,000.00 at your split. These percentages are labeled typical planning splits — move them to fit your project.
A renovation budget is easiest to reason about when you split one big number into the pieces that actually spend it. This allocator does exactly that: you enter the total you are willing to spend, then set what fraction goes to the kitchen, the bath, flooring, labor and everything else. The dollars per category update instantly, so you can see whether a 25% kitchen share is $15,000 or $25,000 before you ever talk to a contractor.
The default percentages are labeled typical planning splits — a common starting point, not a rule. Every home and every project is different, so treat them as a first draft and move them until they match your priorities. The tool also warns you if your shares do not add up to 100%, which is the single most common budgeting slip.
Formula
Each category is a simple share of the total:
category $ = total × category %
and the shares should sum to one:
kitchen% + bath% + flooring% + labor% + other% = 100%
Percentages are entered as fractions (0.25 = 25%). Because the split is pure arithmetic on your own total, the result never depends on current material or labor prices.
Worked example
Say your total budget is $60,000 and you keep the typical split. The kitchen share is $60,000 × 0.25 = $15,000 and the bath share is $60,000 × 0.15 = $9,000. Flooring at 10% is $6,000, labor at 30% is $18,000 and “other” at 20% is $12,000. Those five add back to exactly $60,000, which is the check the tool runs for you.
If you decide the kitchen is the priority, push its share to 0.35 and drop “other” to 0.10: the kitchen line jumps to $21,000 while the total stays fixed. That trade-off — more here means less there — is the whole point of allocating by percentage.
How to use the splits
Treat allocation as a planning conversation, not a verdict. A gut renovation where you are moving walls will carry a much larger labor share than a cosmetic refresh; a kitchen-led remodel naturally tilts toward cabinets and countertops. The percentages exist to make those choices visible, not to prescribe them.
Two habits keep this honest. First, keep the shares summing to 100% — if they do not, the allocator flags it, and you are either under-planning or double-counting. Second, remember that this split does not include a safety buffer: pad the plan separately with the contingency planner, then feed real, itemized quotes back in so the “other” bucket does not quietly absorb every surprise.
When you are ready to build the total from the rooms up rather than the top down, the room-by-room budget works from the opposite direction and meets this tool in the middle.

| Category | Typical share | On your total |
|---|---|---|
| Kitchen | 25% | $15,000.00 |
| Bath | 15% | $9,000.00 |
| Flooring | 10% | $6,000.00 |
| Labor | 30% | $18,000.00 |
| Other | 20% | $12,000.00 |
Frequently asked questions
How should I split a renovation budget?
A common starting point is roughly 25% kitchen, 15% bath, 10% flooring, 30% labor and 20% other, but these are only labeled typicals. Weight the split toward whatever matters most in your project — there is no single correct allocation.
Do the percentages have to add up to 100%?
Yes. If your shares total more or less than 100%, the allocator shows a warning so you can rebalance. Under 100% means part of your budget is unassigned; over 100% means you have promised more than you have.
Where do the default splits come from?
They are widely used planning conventions, labeled as typicals rather than data that ages. Because you can override every share, the tool stays correct no matter how prices move.
Should labor really be almost a third of the budget?
On many remodels labor is the single largest line, especially when trades like plumbing and electrical are involved. On a cosmetic refresh it is far smaller. Adjust the labor share to match your actual scope.
Does the allocator include a contingency buffer?
No. Allocation only divides the money you already have. Add a safety buffer on top with the contingency planner so surprises do not eat a real category.
