📚 Renovation Budget Knowledge

Where the Money Goes

A typical renovation budget breaks down as: labor and structural work (40–50%) — plumbing, electrical, framing, drywall; materials and finishes (30–40%) — flooring, cabinets, countertops, fixtures; appliances and fixtures (15–25%); design and permits (5–10%). For a 1,000 sq ft space, a basic renovation runs $80–120/sq ft ($80,000–120,000), mid-range $150–250/sq ft, and high-end $300+/sq ft. Kitchens and bathrooms are the most expensive rooms per square foot.

Always Pad Your Budget by 10–20%

Renovations almost always go over budget. Common causes include hidden structural issues discovered during demolition (especially in older homes), material price increases, change orders mid-project, and permit delays. Build a 10–20% contingency into your initial budget. If you plan to spend $50,000, have $55,000–60,000 available. Set a hard spending cap and prioritize your must-haves before starting so you can cut nice-to-haves if costs run high.

Financing Options

If you need to borrow for renovations, compare: Home equity loans or HELOCs (interest rates 6–9%, tax-deductible interest, secured by your home); cash-out refinance (replace your mortgage with a larger one, current rates 6–7.5%); personal loans (APR 7–20%, unsecured, no home equity needed); credit cards with 0% intro APR (good for projects under $15,000 paid off within 12–18 months). HELOCs and home equity loans usually offer the lowest rates but put your home at risk if you default.

💡 Tip: Get at least 3 written bids from licensed contractors and check references thoroughly. Never pay more than 10–15% upfront. A clear contract specifying materials, timeline, and payment schedule prevents most disputes. This tool is for reference only.

❓ FAQ

How much does a 100 sqm renovation cost?
At reference tiers: Budget ~$12k, Standard ~$19k, Premium ~$30k (hardworks, materials, furniture, appliances). Add 10-20% for major cities.
Why include a contingency reserve?
90%+ renovations hit surprises. Reserve 3-5% so mid-project discoveries do not stop work.
Why a demolition surcharge for existing homes?
Removing tile, ceilings, or walls costs ~10-15% of hardworks. Skipping it is the #1 reason for "lowball then markup".
