The classic renovation joke: "Budget $30K, finished at $55K." Going over budget isn't bad luck — it's a missing allocation plan. Here's how renovation money is really spent, what to expect per square foot, and how to split the budget so you finish on plan.
The Four Buckets of Renovation Cost
- Hard costs: plumbing, electrical, walls, floors, ceilings, kitchen/bath — the biggest bucket, ~45-55% of budget
- Soft costs: furniture, curtains, lighting, décor — ~25-30%
- Appliances: refrigerator, washer, AC, etc. — ~10-15%
- Contingency: for change orders and surprises — keep 10-15%, this is your overspend insurance
Per-Square-Foot References
| Tier | Hard + soft cost | What you get |
|---|---|---|
| Economy | $80-130 / sq ft | Functional, mid-range materials |
| Mid-range quality | $130-200 / sq ft | Design polish + branded materials |
| Premium | $200-320+ / sq ft | Custom cabinetry, premium finishes |
A 1,000 sq ft home at mid-range runs roughly $130-200K. Reality varies hugely by city, layout, and materials — treat these as guides, not gospel.
Suggested Allocation Ratios
On a $200K total budget:
| Bucket | Amount | Share |
|---|---|---|
| Hard costs | $100K | 50% |
| Soft costs | $50K | 25% |
| Appliances | $25K | 12.5% |
| Contingency | $25K | 12.5% |
Use the percentage calculator to turn these ratios into exact dollar figures before you sign anything.
Three Traps to Avoid
- Low-ball contract, endless change orders: itemize the quote, confirm whether it's "fixed" or "time & materials" — contingency exists precisely for change orders
- Watch the materials: tile, flooring, and boards are change-order hot spots; pin down brands and models in the contract
- Price materials with discounts: during sales, use the discount calculator to find the true rate — don't chase "spend-and-save" headlines; compare the same brand and model
Bottom Line
The secret to finishing a renovation on budget: set a total, split it by ratio, and keep a healthy contingency. Break the budget with the percentage calculator and compare materials with the discount calculator — then every dollar is spent on purpose, and you can actually enjoy the finish line.
