Formula

Loaded price from direct cost, markup and contingency — markup dollars and per-unit price beside the headline.

price = cost × (1 + markup%) × (1 + cont%)

Alternative Form

per unit = price ÷ quantity

Variables

Symbol	Name	Unit	Description
V1	Direct cost	$	Labor + material + subs
V2	Markup	%	Overhead + profit
V3	Contingency	%	Unknowns
V4	Billable units	count	For per-unit
Q	Result	$	Headline answer at full precision.

Explanation

Inputs convert to consistent units first, the formula runs at full precision, then waste and rounding produce the order figure. Cost multiplies by your unit price.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Loaded price = cost x markup x contingency.

P = 100000 x 1.150 x 1.050

Result: 120,750.00

Step 2

Markup dollars plus per-unit over the quantity.

mk = 100000 x 15.00%

Result: 15,000.00 markup; 120,750.00 each

Final Answer

120,750.00

Worked Examples

Scenario

The live inputs above run through the full path below — not just the headline answer.

Inputs

Direct cost:100000 $

Markup:15 %

Contingency:5 %

Billable units:1 count

Calculation

1. Loaded price = cost x markup x contingency. → 120,750.00 2. Markup dollars plus per-unit over the quantity. → 15,000.00 markup; 120,750.00 each

Result

120,750.00 $

Interpretation

Order the uplifted figure, never the net: cuts, defects, rounding and code minimums consume the allowance.

Understanding Your Result

Your Result: Loaded price: 120,750.00 $

Typical range: See the comparisons table below for everyday benchmarks.

What This Means

Your result is 120,750.00 $ (loaded price). That is the engineered figure — verify it against the code table before buying.

Why It Matters

Sizing drives budget, schedule, deliveries and inspections. Small input errors compound across runs, so modelling before buying is the cheapest due diligence.

Professional Interpretation

Plan around 15,000.00 $ (markup dollars), about $120,750.00 at your unit price. Keep same-lot spares for repairs.

How this is calculated

price = cost × (1 + markup%) × (1 + cont%). Loaded price from direct cost, markup and contingency — markup dollars and per-unit price beside the headline.

What drives the result

Input size, the selected option, waste % and whole-unit rounding. Unit price never changes quantity — only cost.

Recommendations

•Split irregular scopes into measurable runs and add the sections.
•Add waste before ordering: x1.10 straight, x1.15 cut-up, x1.20 complex.
•Measure twice — lasers beat tapes past 20 ft; photograph nameplates.
•Keep spares: lots, dye and grain shift between batches.

Educational Content

Introduction

Loaded price from direct cost, markup and contingency — markup dollars and per-unit price beside the headline.

Concept Explanation

Every calculation reduces to price = cost × (1 + markup%) × (1 + cont%), evaluated at full precision after unit conversion. The Steps section shows each substitution so the path is auditable.

Applications

▸Bid pricing and leveling

▸Overhead and margin proofing

▸Pay-app and invoice backup

▸Job reviews and forecasts

▸Lender and owner documentation

Benefits

•One live calculation — no separate tools per size or material
•Steps show every substitution for bid backup
•Waste and rounding separated from net math
•Instant cost, charts and lists from the same numbers

Limitations

•Planning math only — it does not replace stamped design where required
•Allowances use national planning rates; confirm local stock and prices
•Irregular geometry should be split into measurable sections

Best Practices

•Confirm nameplate and table values before ordering
•Keep one unit per field; watch the steps for conversions
•Photograph measurements and labels for dispute-proof records
•Add the trade waste factor before ordering, not after

Common Misconceptions

Myth: Order exactly the computed figure.

Truth: Cuts, defects, fittings and rounding consume 10-20%. Ordering net guarantees a second trip.

Myth: Sticker price picks the cheapest option.

Truth: True cost is installed cost per net unit after waste, labor and contingency — compare that line.

Myth: One rule fits every job.

Truth: Straight runs, retrofits and complex layouts need different allowances — use the sensitivity example.

Practical Tips

•Run one calculation per run, room or phase, then add the order lines.
•Pick stock sizes that divide your runs evenly to cut waste several points.
•Photograph each measurement next to the tape for bid backup.
•Enter your actual unit price to turn the takeoff into a budget in one step.

Common Mistakes

Ordering the net figure with no waste.

Use the order line: net x (1 + waste%) rounded up to whole units.

Mixing units in one run.

Keep one unit per field; the steps show every conversion explicitly.

Forgetting fittings, slack and extras.

Add equivalents and slack first, then apply waste — in that order.

Ignoring lot/batch differences on the second trip.

Order spares from the same lot up front.

Skipping the verification step.

Recompute one line by hand using the FAQ method before paying.

Assumptions

This calculator makes the following assumptions to provide estimates:

Consistent units: Each field uses its stated unit; conversions run before the formula.

Standard conditions: Water at ~60 F; copper electrical at 75 C terminations unless noted.

Code minimums: Results at or above model-code minimums; local amendments may require more.

Limitations

Be aware of these limitations when using this calculator:

Not a stamped design: Planning and takeoff math; get licensed design where the AHJ requires it.

Estimates, not quotes: Cost plans use allowances and your unit price — get 2-3 local quotes.

Frequently Asked Questions

Answers to common questions about this calculator.

What does the Subcontractor Markup Calculator do?

The Subcontractor Markup Calculator covers: loaded price from direct cost, markup and contingency — markup dollars and per-unit price beside the headline. Enter your values above and every result, step, chart and plan updates live.

What is the formula behind the Subcontractor Markup Calculator?

The core formula is price = cost × (1 + markup%) × (1 + cont%). The alternate form shown on the page is per unit = price ÷ quantity. All math runs at full precision; only the display is rounded.

What inputs does the Subcontractor Markup Calculator need?

Enter Direct cost ($, default 100000) and Markup (%, default 15), plus Contingency (%) and Billable units (count). Live steps show each substitution.

What units does the Subcontractor Markup Calculator report?

The headline result is reported in $ (loaded price), with markup dollars in $ and per unit in $ beside it. Keep one consistent input unit per field.

How accurate is the Subcontractor Markup Calculator?

Arithmetic follows directly from your inputs using price = cost × (1 + markup%) × (1 + cont%), so accuracy equals measurement quality. Verify one line by hand (see the verification FAQ), confirm nameplate values, and check against the governing code table before buying.

Can you walk through an example with the Subcontractor Markup Calculator?

With the defaults (direct cost 100000 $, markup 15 %), the calculator substitutes each value into price = cost × (1 + markup%) × (1 + cont%) in the Steps section and lands on the dashboard headline. Change any input to replay the path with your numbers.

Which code or standard governs the Subcontractor Markup Calculator?

AGC/AACE estimating practice and local lien/retainage statutes frame the work; the calculator implements the standard math, and your local amendment has the final word.

How does the Subcontractor Markup Calculator price the job?

Enter any unit price and the dashboard, cost plan and pie chart split materials, labor allowances and a 10% contingency instantly. Leave price blank for an engineering-only answer.

What is the most common mistake with the Subcontractor Markup Calculator?

Mixing units (inches vs feet, kW vs BTU/h, yards vs bags) and skipping waste, coverage and rounding allowances. The Steps section exposes every conversion so a slipped unit is visible immediately.

When should I hire a pro instead of trusting the Subcontractor Markup Calculator?

Use the calculator for planning, takeoffs and quote checks; hire a licensed professional estimator for permitted work, structural/roof changes, fuel and power connections, and anything the inspector must see. Bring the printed steps — pros quote faster with documented numbers.

What is the difference between markup and margin in the Subcontractor Markup Calculator?

A: markup = profit/cost; margin = profit/price. A 20% markup is a 16.7% margin — the Subcontractor Markup Calculator converts both ways so bids quoted either way cross-check before signing.

How much overhead per the Subcontractor Markup Calculator?

A: small contractors run 10-20% overhead, mid-size 15-30% (office, insurance, vehicles, supervision). Overhead $ = direct costs x overhead % — the Subcontractor Markup Calculator spreads it per job or per hour.

How do labor costs build in the Subcontractor Markup Calculator?

A: burdened rate = base wage x 1.25-1.4 (taxes, insurance, benefits); labor $ = hours x rate x crew. The Subcontractor Markup Calculator burdens base rates so bids never carry raw wages.

How do I build a unit price in the Subcontractor Markup Calculator?

A: unit price = (labor + material + equipment)/quantity x (1 + overhead %) x (1 + markup %). The Subcontractor Markup Calculator assembles each layer from your crew rate, production rate and material price.

How do equipment costs work in the Subcontractor Markup Calculator?

A: rental $ = rate x time + delivery/fuel; ownership $ = purchase + finance + insurance + maintenance spread over billable hours. The Subcontractor Markup Calculator time-cost specs run both so rent-vs-own compares fairly.

How do subcontractor costs work in the Subcontractor Markup Calculator?

A: sub cost = quote + extras + tax, carried with your markup applied symmetrically on adds and credits. The Subcontractor Markup Calculator separates sub dollars from your markup so neither hides.

What should my hourly rate be per the Subcontractor Markup Calculator?

A: billable rate = (base wage x burden + hourly overhead + profit share) — typically 2-3x base wage for small shops. The Subcontractor Markup Calculator rate specs build it from your wage, burden and overhead inputs.

How do change orders price in the Subcontractor Markup Calculator?

A: direct cost of the change x (1 + overhead %) x (1 + markup %) plus schedule impact. Document before doing the work — the Subcontractor Markup Calculator prices adds and credits symmetrically.

How does retainage work in the Subcontractor Markup Calculator?

A: owners typically hold 5-10% per pay app until substantial completion; release halves at 50% on many jobs. Retainage $ = billed x % — the Subcontractor Markup Calculator tracks held vs released cash.

How do progress billings work in the Subcontractor Markup Calculator?

A: this invoice = contract x % complete - prior billings - retainage. The Subcontractor Markup Calculator billing specs phase draws across milestones so cash flow stays positive mid-job.

How do deposits work in the Subcontractor Markup Calculator?

A: deposits (often 10-50% down, within state limits) apply against the contract balance — deposit $ = contract x %. The Subcontractor Markup Calculator deposit specs show the deposit and the balance due side by side.

How do I forecast job cost in the Subcontractor Markup Calculator?

A: estimate at completion = actual to date + remaining qty x current unit rate; variance = budget - forecast. The Subcontractor Markup Calculator extrapolates burn rate so overruns surface while they are fixable.

What is break-even per the Subcontractor Markup Calculator?

A: break-even revenue = fixed overhead/(1 - variable-cost ratio). Below it the company loses money even on busy jobs — the Subcontractor Markup Calculator ratios overhead against margin.

How do I compare bids in the Subcontractor Markup Calculator?

A: line up scope, alternates, exclusions and unit prices before comparing bottom lines; the low bid usually excludes something. The Subcontractor Markup Calculator per-unit lines expose unbalanced bids.

How much contingency per the Subcontractor Markup Calculator?

A: 5% for well-defined repeat work, 10% standard bid contingency, 15-20% for renovation/unknowns. Contingency $ = base x % — the Subcontractor Markup Calculator holds it outside markup so it is not double-counted.

How do I handle cost variance in the Subcontractor Markup Calculator?

A: variance $ = actual - budget; variance % = variance/budget x 100. Over 5% triggers reforecast by cost code — the Subcontractor Markup Calculator flags overruns before closeout.

What does insurance cost per the Subcontractor Markup Calculator?

A: general liability, workers comp (by class code and payroll), auto and builder’s risk run roughly 2-6% of revenue for small contractors. The Subcontractor Markup Calculator applies your rate to payroll or contract value.

What do permits cost per the Subcontractor Markup Calculator?

A: base fee plus valuation-based charges (often ~0.5-1.5% of job value) plus trade permits and re-inspection fees. The Subcontractor Markup Calculator totals fixed fees plus valuation charges.

How do I verify the Subcontractor Markup Calculator by hand?

A: total = (labor + material + equipment + subs) x (1 + overhead %) x (1 + markup %) + contingency; margin = profit/price. If hand math differs, check markup-vs-margin and burdened-vs-base wages.

What is the biggest costing mistake the Subcontractor Markup Calculator prevents?

A: bidding labor at base wage with no burden, confusing markup with margin, and forgetting retainage in cash flow — the classic triple that bankrupts busy contractors. The Subcontractor Markup Calculator burdens, separates and phases each.

When should I hire a pro per the Subcontractor Markup Calculator?

A: use a professional estimator for bonded, design-build and multi-prime work; get CPA review of overhead rates yearly. Use the Subcontractor Markup Calculator for planning and checks; use pros for bids that can sink the company.

How do I document the Subcontractor Markup Calculator for a bid or lender?

A: save the steps with quantity takeoffs, crew rates, sub quotes, overhead calc and markup summary. Lenders and owners approve documented bids; unit-price schedules settle change orders.
