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
Earned to date = contract x % complete.
earned = 400000 x 40%
Result: 160,000.00
Step 2
This draw = earned minus prior billings minus retainage.
draw = earned - 120,000.00 - 16,000.00
Result: 24,000.00
Final Answer
24,000.00

Scenario
The live inputs above run through the full path below — not just the headline answer.
Inputs
Contract:400000 $
% complete:40 %
Prior billed:120000 $
Retainage:10 %
Calculation
1. Earned to date = contract x % complete. → 160,000.00 2. This draw = earned minus prior billings minus retainage. → 24,000.00
Result
24,000.00 $
Interpretation
Order the uplifted figure, never the net: cuts, defects, rounding and code minimums consume the allowance.
Understanding Your Result
Your Result: This draw: 24,000.00 $
Typical range: Bill honest percent-complete · mobilization first · subs paid before next draw.
What This Means
Your result is 24,000.00 $ (this draw). 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 160,000.00 $ (earned to date), about $24,000.00 at your unit price. Keep same-lot spares for repairs.
How this is calculated
draw = contract x % - prior - retainage. Progress payment draw from contract, completion, priors and retainage — with billing notes.
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
Progress payment draw from contract, completion, priors and retainage — with billing notes.
Concept Explanation
Every calculation reduces to draw = contract x % - prior - retainage, evaluated at full precision after unit conversion. The Steps section shows each substitution so the path is auditable.
Applications
▸Pay apps
▸Lien waivers
▸Sub payments
▸Cash forecasts
▸Closeout holds
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 Progress Payment Calculator do?
The Progress Payment Calculator covers: progress payment draw from contract, completion, priors and retainage — with billing notes. Enter your values above and every result, step, chart and plan updates live.
What is the formula behind the Progress Payment Calculator?
The core formula is draw = contract x % - prior - retainage. The alternate form shown on the page is front-load mobilization honestly. All math runs at full precision; only the display is rounded.
What inputs does the Progress Payment Calculator need?
Enter Contract ($, default 400000) and % complete (%, default 40), plus Prior billed ($) and Retainage (%). Live steps show each substitution.
What units does the Progress Payment Calculator report?
The headline result is reported in $ (this draw), with earned to date in $ and retained in $ beside it. Keep one consistent input unit per field.
How accurate is the Progress Payment Calculator?
Arithmetic follows directly from your inputs using draw = contract x % - prior - retainage, 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 Progress Payment Calculator?
With the defaults (contract 400000 $, % complete 40 %), the calculator substitutes each value into draw = contract x % - prior - retainage 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 Progress Payment 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 Progress Payment 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 Progress Payment 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 Progress Payment 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.
How do I estimate a job in the Progress Payment Calculator?
A: quantity takeoff x unit price, plus labor hours x burdened rate, plus equipment and subs, plus overhead %, plus markup %, plus contingency %. The Progress Payment Calculator chains each layer so one changed price re-prices the bid.
What is the difference between markup and margin in the Progress Payment Calculator?
A: markup = profit/cost; margin = profit/price. A 20% markup is a 16.7% margin — the Progress Payment Calculator converts both ways so bids quoted either way cross-check.
How much overhead per the Progress Payment Calculator?
A: small contractors run 10-20% overhead, mid-size 15-30% (office, insurance, vehicles, supervision). Overhead $ recovered = direct costs x overhead % — the Progress Payment Calculator spreads it per job or per hour.
How much markup and profit per the Progress Payment Calculator?
A: 10-20% markup is typical for competitive bid work; 20-35% for negotiated/design-build. Profit $ = cost x markup % — the Progress Payment Calculator separates markup dollars from margin percent.
How much contingency per the Progress Payment Calculator?
A: 5% for well-defined repeat work, 10% standard bid contingency, 15-20% for renovation/unknowns. Contingency $ = base x % — the Progress Payment Calculator holds it outside markup so it is not double-counted.
How do I build a unit price in the Progress Payment Calculator?
A: unit price = (labor + material + equipment)/quantity x (1 + overhead %) x (1 + markup %). The Progress Payment Calculator assembles each layer from your crew rate, production rate and material price.
How do labor hours price in the Progress Payment Calculator?
A: burdened rate = base wage x 1.25-1.4 (taxes, insurance, benefits); labor $ = hours x rate x crew. The Progress Payment Calculator burdens base rates automatically at 25% plus your crew multiplier.
How do I check productivity in the Progress Payment Calculator?
A: productivity = quantity/hours (sq ft per crew-hour, units per day). Compare against historical rates — a 20% miss on labor sinks fixed-price bids. The Progress Payment Calculator ratios planned vs actual.
How do material takeoffs work in the Progress Payment Calculator?
A: net quantity from plans, plus waste % (10% straight, 15% cut-up, 20% complex), rounded to whole purchasable units. The Progress Payment Calculator uplifts net to order quantity with waste and rounding.
How do change orders price in the Progress Payment Calculator?
A: direct cost of the change x (1 + overhead %) x (1 + markup %) plus schedule impact. Document before doing the work — the Progress Payment Calculator prices adds and credits symmetrically.
How does retainage work in the Progress Payment Calculator?
A: owners typically hold 5-10% per pay app until substantial completion; release halves at 50% on many jobs. Retainage $ = billed x % — the Progress Payment Calculator tracks held vs released cash.
How do progress payments work in the Progress Payment Calculator?
A: percent-complete x contract value minus prior billings minus retainage = this draw. Front-load mobilization honestly or cash flow goes negative mid-job — the Progress Payment Calculator phases draws across milestones.
How do I forecast final cost in the Progress Payment Calculator?
A: estimate at completion = actual to date + (remaining qty x current unit rate). Variance = budget - forecast — the Progress Payment Calculator extrapolates burn rate to completion.
What is break-even in the Progress Payment Calculator?
A: break-even revenue = fixed overhead/(1 - variable-cost ratio). Below it the company loses money even on busy jobs — the Progress Payment Calculator ratios overhead against margin.
How do I compare bids in the Progress Payment Calculator?
A: line up scope, alternates, exclusions and unit prices before comparing bottom lines; the low bid usually excludes something. Saving = high bid - low bid; % spread flags unbalanced bids.
How does escalation work in the Progress Payment Calculator?
A: escalated cost = base x (1 + rate %)^years. Materials at 3-6%/yr compound fast on multi-year jobs — the Progress Payment Calculator compounds your rate across the schedule.
How do I handle budget variance in the Progress Payment Calculator?
A: variance $ = actual - budget; variance % = variance/budget x 100. Over 5% triggers reforecast — the Progress Payment Calculator flags overruns by cost code.
How do I verify the Progress Payment Calculator by hand?
A: total = (labor + material + equipment + subs) x (1 + overhead %) x (1 + markup %) + contingency; per-unit = total/qty. If hand math differs, check markup-vs-margin and net-vs-order quantities.
What is the biggest mistake the Progress Payment 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 Progress Payment Calculator burdens, separates and phases each.
When should I hire a pro per the Progress Payment Calculator?
A: use a professional estimator for bonded, design-build and multi-prime work; get CPA review of overhead rates yearly. Use the Progress Payment Calculator for planning and checks; use pros for bids that can sink the company.
How do I document the Progress Payment 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.
What records apply to the Progress Payment Calculator job?
A: keep daily logs, delivery tickets, timecards, sub invoices and change-order signatures for 7+ years (lien and tax windows). Certified payroll applies on prevailing-wage jobs.
