The single biggest mistake new sellers make is pricing wrong. Too high: it sits for months. Too low: you’ve left money on the table.
Here’s the formula, by category, that’ll get you within 10% of the optimal price almost every time.
The base formula
Sale price ≈ Original retail × Brand multiplier × Condition multiplier × Age multiplierThat’s it. The trick is knowing the multipliers. Let’s break them down.
Brand multipliers
Brand multipliers reflect how well a brand holds value in the secondary market.
| Brand tier | Examples | Multiplier |
|---|---|---|
| Premium | Stickley, Heywood-Wakefield, Knoll, Herman Miller, Eames originals, Roche Bobois | 0.55–0.75 |
| Designer | Restoration Hardware, West Elm, Crate & Barrel, Room & Board, Ethan Allen | 0.30–0.45 |
| Mass-market quality | Pottery Barn, Williams-Sonoma, Z Gallerie | 0.25–0.35 |
| Big box | IKEA, Wayfair, Ashley | 0.10–0.20 |
| Department store | Macy’s, JCPenney generic | 0.10–0.15 |
A $4,000 Stickley sideboard in good condition: $4,000 × 0.65 = $2,600. A $4,000 IKEA Pax wardrobe: $4,000 × 0.15 = $600. (And IKEA buyers know retail price.)
Condition multipliers
| Condition | Multiplier |
|---|---|
| New (with tags / unused) | 0.85 |
| Like new (almost no wear) | 0.70 |
| Good (light wear, no major damage) | 0.55 |
| Fair (visibly used, fully functional) | 0.35 |
| For parts | 0.10 |
Age multipliers
| Age | Multiplier |
|---|---|
| < 1 year | 0.85 |
| 1–3 years | 0.70 |
| 4–7 years | 0.55 |
| 8–15 years | 0.45 |
| 16–30 years | 0.50 (the dip — modern enough to lose value, not old enough to be vintage) |
| 30+ years | 0.65 (vintage premium kicks in for quality pieces) |
Notice the dip: a 25-year-old Pottery Barn sofa is worth less than a 5-year-old one. But once it crosses ~30 years, mid-century-modern fans drive value back up.
Worked example: Mid-century teak dresser
- Original retail (1972, Danish import): $400 (about $2,800 in 2026 dollars)
- Brand: Mid-tier Danish (call it 0.55)
- Condition: Good (0.55)
- Age: 50+ years (vintage premium 0.85)
Price = $2,800 × 0.55 × 0.55 × 0.85 = $720
That’s pretty close to what these actually sell for in the Gig Harbor market.
Quick cheat sheet by category
For when you don’t want to do the math:
| Category | Original price | Sell-it-fast | Sweet spot | Hold-out |
|---|---|---|---|---|
| Sofa / sectional (5 yrs old, good condition) | $1,500 | $300 | $450 | $650 |
| Dining table (5 yrs old, good) | $800 | $150 | $250 | $400 |
| Bed frame (5 yrs old, good) | $600 | $100 | $200 | $325 |
| Treadmill (3 yrs old, working) | $1,200 | $300 | $475 | $650 |
| Mountain bike (5 yrs old, decent shape) | $1,800 | $350 | $600 | $900 |
| Stand-up paddleboard (3 yrs old) | $700 | $250 | $375 | $475 |
| Patio set (5 pc, 4 yrs old) | $1,000 | $200 | $325 | $475 |
| Lawn mower (5 yrs old, working) | $400 | $80 | $150 | $225 |
What “sell-it-fast” vs “sweet spot” vs “hold-out” mean
- Sell-it-fast: Listed at this price, you’ll have it sold in 1–3 days. Great if you’re moving or just want it gone.
- Sweet spot: Best risk-adjusted return. Sells in 5–10 days, fair to both sides.
- Hold-out: Will sell eventually — could be 2 weeks, could be 8. Right price if you don’t need the space and can wait.
Negotiation buffer
Whatever number you decide on, add 10–15% to your listed price to leave negotiation room. Most buyers will offer 80–90% of asking. If you’re firm at $400, list at $450.
The signals that change the formula
Things that bump price up:
- Original receipt or box
- Original packaging
- Original purchase date documented
- Any unique features (limited edition, custom upholstery, signed)
- Smoke-free / pet-free home
- Multiple high-quality photos showing it’s well-maintained
Things that drop price:
- “Smoking section” smell
- Pet hair / pet damage
- Sun-faded fabric
- Missing parts (“but I have most of it” doesn’t help)
- Need for assembly
Use AI to validate
Our listing wizard uses AI photo recognition to auto-suggest a price range based on similar Gig Harbor sales. It looks at the photos, identifies brand and model when possible, factors in condition, and benches against what’s actually sold locally in the past 90 days. Free, takes 10 seconds. Worth a sanity-check even if you’ve done the math yourself.
