This calculator vs. a flat $189 broken-spring special
Broken-spring service is advertised as one flat number — $189, $249, "we beat any quote." That rate cannot see door class, spring cycle, or the drive, and the same special that clears a small profit six miles from the shop loses money outright forty minutes away.
What a flat broken-spring special is
It is the fastest number to put on a postcard or a search ad: one price, no questions asked, whatever the door turns out to be when the tech arrives. It is learned on a job that was easy to price — usually a single door, a standard-cycle spring, and a short drive — and then quoted again on the next call that comes in.
Nothing about the phone call tells the shop whether the next door is a single or a double, whether the spring is standard or high-cycle, or how far the van has to drive. The special does not ask, because it was never built to answer.
What this calculator is
This page keeps no account and sends nothing to a server. You enter the job type, door width and height, spring kit cost, shop hours, and round-trip miles, plus your own wage, payroll burden, vehicle cost per mile, overhead, and target margin. It prices the ticket from what this specific door and this specific drive actually cost, not a number learned on the last call.
| What a flat $189 special does | What this calculator does instead |
|---|---|
| Charges the same rate for a single 8×7 door and a double 16×7 door, even though the double takes a heavier spring kit and more shop minutes. | Prices the spring kit and shop hours from the door's own class (single or double), so a double door costs more without anyone eyeballing a surcharge. |
| Has no line for spring cycle — a standard-cycle kit and a high-cycle kit, which this calculator's own defaults price 1.6x apart, get the same rate. | Prices a high-cycle spring kit at its own higher parts cost, entered directly rather than guessed. |
| Has no line for travel — a 6-mile round trip and a 42-mile round trip get the same rate. | Prices drive time and vehicle miles separately, and reports the travel share of the price so a short hop and a long haul are never quoted the same. |
| Gives the tech a number to quote over the phone, not a number to check a quote against. | Flags the ticket when travel eats the job — when travel cost is at least 35% of a spring-only ticket's price, or exceeds the shop labor cost outright. |
| Cannot tell you when $189 is a loss rather than a thin margin. | Reports the break-even cost and the price at your target margin, so a flat special can be scored against real cost before you match it. |
Same special, two different tickets
Using this calculator's own shipped cost inputs — $28 hourly wage, 30% payroll burden, $0.75 a mile, 15% overhead, 25% target margin:
A nearby single 8×7 door with a standard-cycle spring kit and a 6-mile round trip (0.2 drive hours) costs $164.66 to run, with travel at $11.78 — 5.4% of the price — and this calculator prices the ticket at $219.54. A flat $189 special still clears $24.34 here, a 12.9% margin, below the 25% target but not a loss.
The same $189 special quoted on a distant double 16×7 door with a high-cycle spring kit and a 42-mile round trip (1.4 drive hours) is a different story. That ticket costs $469.15 to run — travel alone is $82.46, 13.2% of the price and more than the $45.50 of shop labor, which is exactly what trips this calculator's own travel-eats-the-job flag. This calculator prices the ticket at $625.54. The flat $189 special is $280.15 below the job's own break-even cost — a loss, not a thin margin — and $436.54 below what this calculator would charge at a 25% margin. Same advertised number, one ticket profitable and one underwater, and nothing about the phone call that took the booking told the shop which one was coming.
Common questions
Why does a flat $189 broken-spring special get a bid wrong?
Because the number is learned on one job -- typically a nearby single door with a standard-cycle spring -- and then quoted sight unseen on the next call, whatever the door class, spring cycle, or drive turns out to be. This calculator's own shipped defaults price a nearby single-door standard-spring ticket at $219.54 against a total cost of $164.66, so a $189 special still clears $24.34 there. The same $189 special quoted on a distant double door with a high-cycle spring is $280.15 below that job's $469.15 break-even cost -- a loss, not a thin margin, on a job this calculator prices at $625.54.
What does a flat broken-spring special usually miss entirely?
Door class (a double door takes a heavier torsion kit and more shop minutes than a single), spring cycle (a high-cycle kit runs 1.6x a standard kit's cost), and travel (drive time and vehicle miles do not shrink because the ticket is a spring, not a door). A flat rate has no line for any of them -- it is one number learned on one job and reused for the next call that comes in, regardless of how far the van has to go.
How big is the pricing gap in practice?
Using this calculator's own shipped cost inputs -- $28 hourly wage, 30% burden, $0.75 a mile, 15% overhead, 25% target margin: a nearby single 8x7 door with a standard-cycle spring and a 6-mile round trip costs $164.66 to run and this calculator prices it at $219.54. A distant double 16x7 door with a high-cycle spring and a 42-mile round trip costs $469.15 to run and prices at $625.54. Quoting both at the same $189 flat special leaves $24.34 on the near job and a $280.15 loss on the far one -- a swing of over $500 hidden inside one advertised number.
Is a flat broken-spring special ever a reasonable shorthand?
For calls that stay close to the shop, on single doors with a standard-cycle spring, a flat number can land close to cost. The risk is quoting a double door, a high-cycle kit, or a long drive the same way over the phone, because the advertised rate does not know any of that until the tech is already on site -- and by then the $189 has often already been promised.
Does this calculator know my local labor rates or parts pricing?
No. It has no data on your local labor market or your supplier's kit pricing. It takes the job type, door size, spring kit, shop hours, and round-trip miles, plus your own wage, payroll burden, vehicle cost per mile, overhead, and target margin, and turns that into a price for this ticket -- the arithmetic a flat special skips, not a market survey.
