This calculator vs. a flat $99 dryer vent special
A "$99 dryer vent special" is not a price for a dryer vent clean — it is a coupon-page number, and on this calculator's own arithmetic it doesn't even clear the one-story wall cap it's named for.
What a flat $99 special is
A flat dollar figure is the fastest thing to put on a flyer or a coupon site: one number, easy to remember, and the number a caller holding a competitor's ad will ask you to match on their own house.
The number behind it was set to sound cheap, not to cover the shortest job it could describe — and then quoted again for every house afterward, whether or not the next one has a second story, a longer duct run, an extra dryer, a camera pass, crushed flex to replace, a nest to clear, or a roof cap to access.
What this calculator is
This page keeps no account and sends nothing to a server. You enter the job type, stories, duct run, extra dryers, a camera pass, flex replacement, a nest or blockage, occupied-home access, and your own wage, material, and overhead rates. It prices the base setup, every story and foot beyond it, extra dryers, and each extra separately, and returns a break-even price and price per dryer below which the job loses money — for this house, not a flyer number.
| Job | $99 special | Break-even price | Verdict |
|---|---|---|---|
| 1-story wall cap, 8 ft run, 1 dryer (the flat special's own job) | $99.00 | $128.39 | Short $29.39 |
| 2-story wall or soffit, 18 ft run, 1 dryer | $99.00 | $196.45 | Short $97.45 |
| Roof cap, 2 stories, 28 ft run, camera pass, occupied home | $99.00 | $392.14 | Short $293.14 |
| Duplex laundry, 2 extra dryers, 22 ft run, camera, flex, nest, occupied | $99.00 | $507.23 | Short $408.23 |
Worked using this calculator's own shipped defaults: a $38 hourly wage, 32% payroll burden, 16% overhead on direct cost, and the job type's own suggested base-setup hours — not numbers invented for this page. Open the calculator to check any row yourself.
Notice the first row: it is the exact job the flat rate is named for — the shortest wall-cap run this calculator can describe — and it is already $29.39 short of break-even before a second story, an extra foot of duct, or a single extra is added. Every row after that only widens the gap.
| What a flat $99 special does | What this calculator does instead |
|---|---|
| Charges the same figure whether the job is a one-story wall cap with eight feet of pipe or a two-story roof cap with a 28-foot run and a camera pass. | Prices a base setup, then adds hours for every story and foot of run beyond it, so a longer, higher job costs more than a short one. |
| Has no separate line for a second or third dryer sharing the same laundry closet. | Adds hours per extra dryer beyond the first, and reports the price per dryer alongside the total. |
| Prices "a dryer vent" the same whether or not a camera pass, crushed-flex replacement, or a nest is involved. | Adds hours and a materials fee for a camera pass, flex replacement, and a nest or blockage only when each applies. |
| Has no line for a roof-cap termination's safety kit or the extra care an occupied home needs. | Adds a roof safety kit on roof-cap jobs and extra hours for occupied-home access when either applies. |
| Gives the homeowner a number to shop, not a figure to check a quote against when their house turns out to be two stories with a nest in the vent after the flat rate was already promised. | Reports the break-even price and price per dryer for the job as entered, so a shopped rate can be scored against real cost before it is confirmed. |
A flat $99 special is not wrong because it is simple — it is wrong when it is quoted for a job it was never priced on, and "a dryer vent" alone never tells you that has happened. This calculator does not replace judgment about your market; it replaces the arithmetic a flat rate skips.
Common questions
Why doesn't a flat $99 dryer vent special cover its own job?
Because the $99 figure is usually set to sound cheap on a flyer, not derived from loaded labor, brush and rod material, and overhead for the exact one-story wall-cap job it is named for. On this calculator's own defaults — a $38 hourly wage, 32% burden, 16% overhead, and the job's own base-setup and travel hours — the simplest possible job it could describe, a one-story wall cap with an eight-foot run and one dryer, already breaks even at $128.39: $29.39 more than the flat rate before a single extra story, foot, or dryer is added.
What does a flat $99 special usually leave out entirely?
Every story and foot of run beyond the shortest possible setup, extra dryers, a camera pass, crushed-flex replacement in the laundry closet, a bird nest or heavy blockage, occupied-home access, and a roof-cap termination's safety kit. A published flat number is set on one configuration — usually the shortest wall-cap run a coupon page can advertise — and has no separate line for any of those.
How much do extra stories, run feet, and extras actually add over a flat special?
On this calculator's own worked examples, at a $38 hourly wage, 32% burden, 16% overhead, and the form's own shipped rates: a two-story wall or soffit job with an 18-foot run and one dryer breaks even at $196.45, $97.45 short of a $99 special. A roof-cap termination with two stories, a 28-foot run, a camera pass, and occupied-home access breaks even at $392.14, $293.14 short. A duplex laundry with two extra dryers, a camera pass, flex replacement, a nest, and occupied access breaks even at $507.23, $408.23 short.
Is a flat $99 special ever the right way to price a dryer vent job?
On this calculator's own numbers, not even the shortest job it can describe clears it: a one-story wall cap with an eight-foot run and one dryer already breaks even $29.39 above the flat rate. The gap only widens from there as stories, run feet, extra dryers, a camera pass, flex replacement, a nest, or occupied-home access are added, because a flat per-job number has no way to see any of them until the tech is already on the ladder.
Does this calculator know what to charge in my market?
No. It has no data on local labor rates or what competitors charge. It takes the job type, stories, run feet, extra dryers, camera pass, flex replacement, nest, occupied access, and your own wage, burden, and overhead, and turns them into a break-even price for the job you describe — the arithmetic a flat special skips, not a market survey.
Nothing here says or implies that quoting a flat $99 special is a bad-faith practice — it is a common, honest shortcut that works until the job stops matching the shortest run it was set on. This page describes where that shortcut breaks down, not a fault in anyone who uses it.
