Wood Fence vs Vinyl Fence: 25-Year Cost Calculator

How the wood vs vinyl comparison works

A fence has three costs over 25 years, not one: the upfront build, the replacement, and the resale value at the end. Wood is built twice over 25 years — at year 0 and again at year 15 — because it lasts about 15 years. Vinyl is built once, because it lasts about 30 years. Wood is also worth about $2,000 to the house when it sells, while vinyl is worth about $3,000; the net cost is the gross cost minus that resale value. Divide by 25 and you have the net cost per year.

At the defaults — 150 ft, wood $30.00/ft installed, vinyl $45.00/ft installed, wood $2,000 resale, vinyl $3,000 resale — the wood upfront is 150 × $30.00 = $4,500.00 and the vinyl upfront is 150 × $45.00 = $6,750.00, so wood wins upfront by $2,250.00. The wood gross is $9,000.00 and the vinyl gross is $6,750.00, so vinyl wins gross by $2,250.00. And the wood net is $9,000.00 − $2,000.00 = $7,000.00 while the vinyl net is $6,750.00 − $3,000.00 = $3,750.00 — so vinyl wins net by $3,250.00, or $280.00 a year against $150.00.

The worked example, line by line

Setup: 150 ft; wood $30.00/ft installed, $2,000 resale; vinyl $45.00/ft installed, $3,000 resale; 25-year horizon.

Line 1 — the upfront cost. Wood: 150 × $30.00 = $4,500.00. Vinyl: 150 × $45.00 = $6,750.00. Wood wins by $2,250.00.

Line 2 — the applications. Wood lasts 15 years, so over a 25-year horizon it is built twice (years 0 and 15). Vinyl lasts 30 years, so it is built once.

Line 3 — the 25-year gross. Wood: 2 × $4,500.00 = $9,000.00. Vinyl: 1 × $6,750.00 = $6,750.00. Vinyl wins by $2,250.00.

Line 4 — the 25-year net. Wood: $9,000.00 − $2,000.00 = $7,000.00. Vinyl: $6,750.00 − $3,000.00 = $3,750.00. Vinyl wins by $3,250.00.

Line 5 — the net cost per year. Wood: $7,000.00 ÷ 25 = $280.00/yr. Vinyl: $3,750.00 ÷ 25 = $150.00/yr.

Line 6 — the break-even vinyl price. Vinyl ties wood on net cost when its installed price is ($7,000.00 + $3,000.00) ÷ 150 = $66.67/ft. Buy vinyl below that and vinyl wins net; above it, wood wins net. At $66.67 a foot the vinyl net is $7,000.50 — fifty cents above the tie, because $66.67 is the break-even rounded up from $66.6667.

Every branch, checked

100 ft: the wood upfront is 100 × $30.00 = $3,000.00 and the vinyl upfront is 100 × $45.00 = $4,500.00 (wood by $1,500.00); the gross is $6,000.00 against $4,500.00 (vinyl by $1,500.00); and the net is $4,000.00 against $1,500.00 (vinyl by $2,500.00), or $160.00 a year against $60.00. A shorter fence shrinks every number by a third, but the winner is the same at every length.

Wood at $20.00/ft: the wood upfront falls to 150 × $20.00 = $3,000.00, so the gross is $6,000.00 and the net is $6,000.00 − $2,000.00 = $4,000.00 against $3,750.00 for vinyl — vinyl wins net by $250.00, or $160.00 a year against $150.00. Cheap wood wins gross by $750.00, but it still loses net: two cheap fences still cost more than one dear one.

Vinyl at $35.00/ft: the vinyl upfront falls to 150 × $35.00 = $5,250.00, so the gross is $5,250.00 and the net is $5,250.00 − $3,000.00 = $2,250.00 against $7,000.00 for wood — vinyl wins net by $4,750.00, or $90.00 a year against $280.00. Cheap vinyl wins at every stage except upfront, where wood still wins by $750.00.

Resale $0: with no resale value, the wood net is the gross cost: $9,000.00 against $6,750.00 for vinyl, so vinyl wins net by $2,250.00, or $360.00 a year against $270.00. Vinyl does not need the resale value to win: one vinyl fence is cheaper than two wood fences on its own.

200 ft: the wood upfront is 200 × $30.00 = $6,000.00 and the vinyl upfront is 200 × $45.00 = $9,000.00 (wood by $3,000.00); the gross is $12,000.00 against $9,000.00 (vinyl by $3,000.00); and the net is $10,000.00 against $6,000.00 (vinyl by $4,000.00), or $400.00 a year against $240.00. A longer fence widens the gap in dollars, but the winner is the same at every length.

Reverse — the break-even vinyl price: vinyl ties wood on net cost when its installed price is ($7,000.00 + $3,000.00) ÷ 150 = $66.67/ft. At $45.00 a foot vinyl is well below that, so vinyl wins net by $3,250.00; at $70.00 a foot it is above, so wood wins net. The $66.67 line is where the two fences are exactly equal over 25 years.

What the defaults assume

The model counts build, replacement, and resale only: it does not count the cost of removing the old fence, the grading, the gates, the staining or the painting. It assumes wood lasts 15 years and is replaced once at the same price — in reality a wood fence in a wet climate can rot in 10 years, and a stained fence can last 20. It assumes vinyl lasts 30 years and is never replaced — in reality a vinyl fence in a storm can crack a panel, which this model does not count. It assumes the resale values hold: vinyl adds about $3,000 to a house and wood about $2,000, but the real numbers depend on the buyer and the market. It assumes prices stay flat for 25 years, which they will not. Rounding convention: money is rounded to cents and all figures are computed from unrounded values, rounded only for display.

Who uses this

• The homeowner replacing a rotting wood fence: they learn vinyl costs $3,750.00 net over 25 years against $7,000.00 for wood — and vinyl never needs painting, so the fence that looks better is also the cheaper one.
• The landlord fencing a rental yard: they will never see the resale value, but with resale at $0 vinyl still wins net by $2,250.00 — so they build vinyl, knowing the wood would need replacing before the tenant moves out.
• The homeowner who found cheap wood: at $20.00 a foot installed, wood wins gross by $750.00 — but vinyl still wins net by $250.00, so they check the net before they buy the cheap boards.
• The renovator fencing a long lot: at 200 ft vinyl wins net by $4,000.00 — so they price the whole lot, not the first 50 ft, before they decide.

Accuracy & limitations

The math is exact for the numbers you enter: the upfront is the length times the installed price, the gross adds the replacement, and the net subtracts the resale value. What the model cannot do is know your yard: wood in a wet climate can rot in 10 years, and vinyl in a storm can crack a panel. It leaves out removal of the old fence, grading, gates, staining, and painting — ask the contractor whether the quote includes those. It assumes the resale values hold, but the real numbers depend on the buyer and the market, and a buyer who plans to re-fence will pay nothing for it. It assumes prices stay flat for 25 years, which they will not: wood and vinyl prices move with lumber and with resin.
