IPE vs Composite Calculator
The premium-tier wood-vs-synthetic decision tool — IPE Brazilian Walnut (or Cumaru / Tigerwood variants) against capped composite (Trex / TimberTech / Fiberon / Deckorators). 10-dimension scoreboard: installed cost · 25-yr TCO · lifespan · Janka hardness · heat retention · warranty · color options · sustainability + FSC availability · weight · DIY friendliness. Janka hardness bar visualizes IPE 3,680 lb (5× harder than oak) vs composite ~1,100 lb. Sustainability flag forces composite if FSC-IPE supply is constrained (Cumaru 22% / IPE 28% / Tigerwood 35%). Will-you-oil toggle adjusts TCO by $1,500-2,500 depending on the silver-vs-brown decision.

IPE (Brazilian Walnut) vs Premium capped composite · 192 sqft · PA (Northeast)
Install premium for IPE is $5,040 (32% of composite cost). Without 25+ year ownership to amortize, composite is the rational choice. 35-yr fade & stain warranty + Trex Transcend's recognized brand at resale. 12 engineered colors vs IPE's 3 natural tones. Self-tap clip install in 50-80 hr vs IPE's 80-150 hr.
Caveat: Composite picked, but IPE (Brazilian Walnut)'s Janka 3680 lb is 3.1× harder than composite. For high-traffic commercial decks, dock surfaces, or where chair-leg/pet-claw scratching matters, IPE's hardness advantage may justify the premium.

Janka hardness (lb)
Janka measures force (lbs) to embed a 11.28 mm steel ball halfway into wood. Red oak (1,290 lb) is the reference. Higher = harder = better dent / scratch resistance. IPE 3,680 lb is among the hardest commercial woods globally; composite cap is ~1,100-1,200 — equivalent to soft maple.
10-dimension scoreboard
| Dimension | IPE | Composite | Winner |
|---|---|---|---|
Installed cost IPE labor runs $18-30/sqft (pre-drill required) vs composite $14-24. IPE board $/lf 30-40% higher. Total install gap typically $3,500-7,000 on a 200-sqft deck. | $20,645 | $15,605 | Comp |
25-yr TCO Install + 25-yr maintenance + 6 oil applications. IPE silvering (skip oil) cuts the gap. Over 50 yr IPE wins decisively — composite needs replacement at year 28-32, IPE lasts 40-50. | $22,834 | $15,845 | Comp |
Expected lifespan IPE's density (69 lb/cf) and natural extractives resist rot indefinitely. Composite cap eventually wears or fades beyond warranty. Real-world: 50-yr IPE decks in Brazil still in service; 25-yr-old Trex decks typically show cap micro-abrasion. | 50 yr | 32 yr | IPE |
Janka hardness Janka 3,680 (IPE) means 5× harder than red oak. Resists chair-leg dents, pet-claw scratches, dropped tools. Composite cap is ~1,100-1,200 — equivalent to soft maple. Critical for high-traffic commercial decks. | 3680 lb | ~1200 lb | IPE |
Heat retention (sunny 90°F) Real-wood surface (IPE) retains less radiant heat than composite organic-fiber cap. IPE in summer sun ~98°F vs composite ~108°F at 90°F ambient. Light-color composite (Trex Toasted Sand) closes the gap. | +8°F | +15°F | IPE |
Warranty coverage Composite gets manufacturer warranty — fade/stain coverage typically 25-35 yr + structural 25-50 yr. IPE has zero warranty; you bet on the lumber yard's grade selection. Premium dealers (AdvantageLumber, BuyTropicalWood) offer return windows but no long-term coverage. | None (natural wood) | 35-yr fade & stain | Comp |
Color / finish options Composite offers 12-13 engineered colors (Trex Transcend has 13). IPE has 3 natural tones (light olive, walnut-brown, silver-grey). Stain IPE = possible but uncommon. Skip oil and IPE silvers within 1 yr — popular cottage look. | 3 natural tones | 12 colors | Comp |
Sustainability + FSC Composite captures ~85% recycled content. FSC-certified IPE represents 22-35% of market supply (variant-dependent). Without FSC certification, IPE supports illegal logging in Brazilian Amazon. Sustainability-flag toggle forces composite if FSC unavailable. | FSC 28% of supply | 85% recycled | Comp |
Board weight IPE's 69 lb/cf density makes boards heavier than composite (~5.5-6 lb/sqft). Slightly more PT framing required. Practical impact: 2-person carry per board; install slower; substructure spec slightly stiffer. | 6.2 lb/sqft | 5.85 lb/sqft | Comp |
DIY friendliness IPE's hardness means EVERY screw needs pre-drilling — 3 holes per fastening point with carbide bits. 3-4× longer install time than composite. Pre-drilled IPE deck = 80-150 hr DIY for 200 sqft; composite = 50-80 hr. Specialty hidden clips (Tiger Claw IPE) required. | Pre-drill required | Self-tap clips | Comp |
| Total dimension wins | IPE 3·Comp 7 | ||
IPE excels on hardness, lifespan, heat. Composite wins on warranty, DIY-friendliness, sustainability + cost. Sustainability flag overrides ranking if FSC-IPE supply is too constrained (28% of US market).

How to use
How to use the Ipe vs composite comparison in 5 steps.
- 1
Enter deck size + state
Length × width in feet, shape (rect / L-shape). 2-letter state for regional labor (NE 1.22× / W 1.28× / S 0.92× / MW 1.00×). IPE labor runs $18-30/sqft vs composite $14-24 — labor delta drives much of the install gap.
- 2
Pick IPE variant
IPE ($13.50/lf, Janka 3,680, FSC 28%) is the benchmark. Cumaru ($11/lf, Janka 3,540, FSC 22%) is the 18%-cheaper alternative with 96% the hardness. Tigerwood ($10.25/lf, Janka 2,160, FSC 35%) trades hardness for the most readily-FSC-certified variant and the most visually distinctive grain (bold dark stripes).
- 3
Pick composite tier
Entry ($3.75/lf), mid ($6.25/lf — Trex Select), or premium ($9.25/lf — Trex Transcend, TimberTech LEGACY). The premium tier is the realistic IPE alternative — entry composite isn't in the same quality league.
- 4
Will you re-oil IPE?
Yes (default) = $1.45-1.65/sqft × area every 4 yr to preserve color. No = let IPE silver naturally within 12-18 months. Skipping oil saves significant TCO. Decide before install — silvered IPE doesn't return to brown without sanding + oiling.
- 5
Sustainability flag
ON forces composite if FSC-IPE availability is low (IPE 28%, Cumaru 22%, Tigerwood 35%). Without FSC chain-of-custody, IPE may originate from Amazon illegal logging. Composite captures 85% recycled content. If FSC-certified IPE matters but you don't want composite, verify your dealer's certificate before purchase.
How we calculate
How DeckMath calculates this — IRC 2021 sources.
The IPE vs Composite Calculator is the premium-tier wood-vs-synthetic decision tool. Compares IPE Brazilian Walnut (or Cumaru / Tigerwood variants) against capped composite (Trex / TimberTech / Fiberon / Deckorators). 10-dimension scoreboard: installed cost · 25-yr TCO · lifespan · Janka hardness · heat retention · warranty · color options · sustainability + FSC availability · weight · DIY friendliness. Sustainability flag forces composite when FSC-certified IPE availability is low (Cumaru 22%, IPE 28%, Tigerwood 35% of market). Will-you-oil-IPE toggle removes the $1.45-1.65/sqft re-oiling cost if you accept the natural silver-grey patina. Built on 2026-Q1 retail + AdvantageLumber/BuyTropicalWood premium dealer pricing. Pairs with 25-Year Deck Cost Calculator (lifecycle) and Composite vs PVC Calculator (synthetic-class decision).

2026-Q1 retail pricing. IPE $13.50/lf, Cumaru $11.00/lf, Tigerwood $10.25/lf — AdvantageLumber + BuyTropicalWood premium dealer averages. Composite $3.75-9.25/lf retail (Home Depot/Lowe's). IPE labor $18-30/sqft vs composite $14-24/sqft (pre-drill-every-screw requirement). Janka hardness from USDA Forest Products Lab. FSC availability percentages from FSC International + Rainforest Alliance market reports.
Board LF = area / 0.458 × 10% waste (slightly higher than composite due to IPE grade-sorting). Fasteners $0.95/sqft (Tiger Claw IPE clips). Framing $7.50/sqft. Railing IPE $95/lf vs composite $65/lf. IPE stairs 20% premium (pre-drill stringers). Labor: IPE $18-30/sqft (pre-drill every screw with carbide bit) × regional × 0.88-1.12 spread. Composite labor $14-24/sqft × region. Contingency 8%. IPE install premium ~$3,500-7,000 on 200-sqft deck.
Maintenance both: $0.05-0.07/sqft/yr cleaning. IPE adds re-oil every 4 yr if willOilIpe = true (6 events over 25 yr × $1.45-1.65/sqft × area). On a 200-sqft deck: oil cost = 6 × $1.65 × 200 = $1,980 added to IPE TCO. Skipping oil saves this — IPE silvers within 12 months. Composite never oils; cleaning only.
IPE's density (60-69 lb/cf) + natural rot-resistance compounds (lapachol in IPE) give 40-50 yr lifespan with minimal care. Composite cap eventually wears or fades beyond warranty (25-35 yr fade/stain). Over a 50-yr horizon IPE wins decisively — no replacement needed; composite needs 1 full replacement at year 28-32. Over a 25-yr horizon composite ties or wins on TCO.
IPE 3,680 lb (Janka). Cumaru 3,540. Tigerwood 2,160. Red oak 1,290 (reference). Composite cap ~1,100-1,200. Hardness matters for: chair-leg dents, pet-claw scratches, dropped tools, heavy foot traffic. Commercial decks specify Janka 2,000+ minimum — only IPE and Cumaru meet this without exception. Composite at Janka 1,100 dents under chair legs over decades.
Forest Stewardship Council certification verifies the harvest doesn't involve illegal logging or unsustainable practices. IPE 28% of US market supply is FSC-certified. Cumaru 22%. Tigerwood 35% (best). Non-FSC IPE may originate from Brazilian Amazon illegal logging — environmentally damaging + legally risky if Lacey Act enforcement strengthens. Verify dealer's FSC chain-of-custody certificate (look for FSC-C number) before purchase.

Ipe vs composite questions, answered.
On lifespan + hardness + heat — yes. IPE lasts 40-50 yr vs composite 25-32 yr. IPE Janka 3,680 lb is 3× harder than composite cap. IPE retains 8°F less heat than premium composite. On cost + warranty + sustainability + DIY-friendliness — composite wins. Composite install is $3,500-7,000 cheaper. Composite has 25-35 yr fade/stain warranty (IPE has none). Composite is 85% recycled content vs IPE's variable FSC supply. Composite installs in 50-80 hr DIY vs IPE 80-150 hr. Pick IPE for forever-home premium build; pick composite for warranty + budget + sustainability + faster install.
For a 200-sqft (16×12) deck installed in the Northeast (1.22× labor) at 2026-Q1 pricing: IPE total $14,500-16,800 high estimate. Premium composite (Trex Transcend) $9,800-11,200 high. Mid composite (Trex Select) $7,400-8,800 high. Entry composite (Trex Enhance) $5,200-6,400 high. IPE costs roughly 1.5-2× premium composite, 2× mid composite. Cumaru saves 18% vs IPE; Tigerwood saves 24% vs IPE while still beating premium composite on hardness.
Optional, but recommended every 3-4 years if you want to preserve color. Penetrating oil (Penofin Hardwood, Cabot Australian Timber, Messmer's UV Plus for Hardwood) costs $1.45-1.65/sqft per application. Skip the oil and IPE silvers to uniform grey within 12-18 months — a popular coastal/cottage look. Decision must be made before install (or in the first oil cycle): silvered IPE doesn't return to brown without sanding + oiling. Over 25 yr the oil cycle adds ~$2,000 to TCO on a 200-sqft deck. Cumaru and Tigerwood need same oil cycle as IPE.
40-50 years with proper care, longer in dry climates. The benchmark is 50-year-old IPE installations in São Paulo still in service. Lapachol (a natural rot-resistance compound in IPE heartwood) + Janka 3,680 density + sapwood-free grade-sorting deliver borderline-indefinite life. Cumaru 45 yr. Tigerwood 40 yr. By comparison composite 25-32 yr (premium tier), then cap wear / fade beyond warranty. IPE outlasts most owners' tenure in the home.
Only when FSC-certified. FSC chain-of-custody verifies harvest from sustainable forest management with no illegal logging. FSC-IPE is 28% of US market supply; non-FSC IPE may originate from Brazilian Amazon illegal logging. The Lacey Act (US 16 U.S.C. § 3371) requires legal-source declarations for imported hardwoods — non-FSC IPE carries some compliance risk. If sustainability is a deciding factor: (1) demand your dealer's FSC chain-of-custody certificate (look for FSC-C number), (2) consider Tigerwood (FSC 35% — best availability), or (3) pick composite (85% recycled content, no sourcing concerns).
Yes, but it's 50-100% harder than composite DIY. Every screw requires pre-drilling 3 holes with carbide-tipped bits (or stainless deck screws). IPE's Janka 3,680 hardness means standard drill bits dull instantly. Hidden-fastener clips need IPE-specific systems (Tiger Claw IPE, Camo Edge HF-IPE) at ~$1.50/sqft fastener cost vs $0.85 for composite. Sawing requires carbide blades. Cuts mineral-rich IPE dust (use respirator). Total DIY hours for 200-sqft IPE deck: 80-150 hr depending on skill, vs 50-80 hr for composite. Pre-drilling is the time sink.
Yes — 96% the hardness at 18% less cost. Cumaru (Dipteryx odorata, also called Brazilian Teak) is the closest IPE substitute. Janka 3,540 (vs IPE 3,680). Lifespan 45 yr (vs IPE 50). Color honey-tan with darker streaks (more varied than IPE's olive-walnut). Same install regimen — pre-drill required, IPE-class hidden fasteners. FSC availability slightly lower than IPE (22% vs 28%). Visually distinct enough that some prefer it. Cost savings on a 200-sqft deck: ~$1,200 vs IPE.
Tigerwood (Gonçalo Alves / Astronium graveolens) is the most visually distinctive tropical hardwood — bold dark-stripe pattern over honey-orange base, like its namesake. Janka 2,160 (less than IPE/Cumaru, still 1.6× harder than red oak). Lifespan 40 yr. FSC availability is highest of the three at 35%. Color is the major sell — striking, varied, no two boards alike. Trades raw hardness for sustainability + cost ($10.25/lf vs IPE $13.50). Best pick if you want a tropical hardwood look that's both visually distinctive and reasonably FSC-available.
Composite or PVC, not IPE. Pool decks face constant chlorinated splashback, occasional saltwater (saltwater pools, coastal homes), and humidity. IPE handles moisture fine (rot-resistant) but the oil cycle gets disrupted (oil doesn't penetrate wet/chlorinated wood well). Composite/PVC's no-maintenance-cleaning regime suits pool environments better. If you want premium-pool look, pick AZEK Vintage PVC or Trex Signature (mineral-polymer) — both deliver hardwood-realistic looks at composite/PVC pool-deck performance. Save IPE for non-pool premium decks.
Yes, slightly. Per Remodeling Cost vs Value Report 2024 (extrapolated for tropical hardwood): IPE recoups ~78% at resale; premium composite ~72%. The 6pp delta reflects: (1) appraisers recognize IPE's premium reputation, (2) luxury-home buyers pay premium for genuine hardwood, (3) IPE photographs better in listings. The recoup advantage doesn't fully offset IPE's install premium for sub-20-yr ownership horizons — composite still wins net cost. For 25+ yr ownership, IPE's higher recoup + longer lifespan + no replacement combine to make it lifecycle-competitive.
