What the Ganarpro Cleaning Calculator 2025 calls “the brain that processes everything.”

That “brain” is the core calculation engine, This is where every input — area, type, labor rate, add-ons, phases, etc. — is unified into a single pricing output.

Here’s a complete breakdown of what it does, step-by-step 👇

🧠 1. Calculates Base Hours

“Calculates base hours using area, productivity, and passes”

The calculator first determines how many labor hours are needed before any money is calculated.

const roughHrsBase = (areaM2 * wR) / effProd.rough_m2_hr;
const finalHrsBase = (areaM2 * wF) / effProd.final_m2_hr;
const fluffHrsBase = (areaM2 * wFl) / effProd.fluff_m2_hr;

Then it scales each phase (rough, final, fluff) by the number of passes entered:

const roughHrs = roughHrsBase * phasePasses.rough;
const finalHrs = finalHrsBase * phasePasses.final;
const fluffHrs = fluffHrsBase * phasePasses.fluff;

Finally, it totals everything:

const laborHours = roughHrs + finalHrs + fluffHrs;

✅ Result: the raw cleaning time for the building based on its size and how many passes each phase needs.

⚙️ 2. Applies All Multipliers

“Applies all multipliers”

Before turning hours into money, the calculator modifies productivity and rates using several real-world factors:

• Location factor (e.g., California = +15%, Alabama = -11%)
• Building type factor (e.g., Healthcare slower, Warehouse faster)
• Size factor (smaller buildings take proportionally more time)
• Level penalty (+3% per floor)
• Phase premium (+15% for each additional active phase)

Example:

const phaseFactor = 1 + (enabledPhasesCount - 1) * 0.15;
const lvlMult = 1 + (levels - 1) * 0.03;

These ensure the calculator adjusts pricing for complexity, logistics, and access.

✅ Result: realistic scaling for building difficulty, height, and region.

💰 3. Computes Labor-Based and Area-Based Pricing

“Computes both labor-based and area-based pricing”

The system runs two parallel pricing models and then uses whichever yields the higher result:

1. Labor-based pricing const laborCost = laborHours * labor.rate_per_hour; const basePreMargin = laborCost * phaseFactor + allAddOns;
2. Area-based pricing const effectiveSqftRate = nationalBaseSqft × locRateMult × typeRateMult; const minByArea = areaFt2 × effectiveSqftRate;

It then takes the larger:

const adjustedBaseCost = Math.max(basePreMargin, minByArea);

Then applies profit margins:

totals = {
  market_win: adjustedBaseCost * 1.07,
  lean: adjustedBaseCost * 1.15,
  profit_heavy: adjustedBaseCost * 1.28,
};

✅ Result: ensures pricing never drops below a fair per-ft² minimum, even if labor math produces a lower figure.

🔌 4. Integrates All Add-Ons

“Integrates all add-ons”

Each optional add-on (Windows, Pressure Wash, Flooring, Units, etc.) is calculated separately and added into the total.

Add-on examples:

pressureCost = pressure.enabled ? pressure.area × pressure.rate_per_unit : 0;
flooringCost = flooring.enabled ? flooring.area × coats × price_per_coat : 0;
windowCost = windows.enabled ? panes × price_per_pane × levelFactor : 0;

All of them feed back into the main total:

basePreMargin = (laborCost * phaseFactor) + pressureCost + flooringCost + unitsBathsCost + windowCost;

✅ Result: You get one unified total that accounts for every enabled option in the UI.

🧩 5. Produces the Final “Selected Bid”

Finally, the “brain” decides what number to display as your Selected Bid, based on what’s active:

• If T&M Override is on → uses man-hour total
• Else if Janitorial Mode is on → uses recurring pricing
• Else → uses the selected margin model (Market-Win, Lean, or Profit-Heavy)

let selectedBid = totals[selectedModel];
if (janitorial.enabled && janitorial.apply_to_selected) { selectedBid = janTotal; }
if (manHour.enabled && manHour.apply_to_selected) { selectedBid = manHourTotal; }

✅ Result: the final number you’d use for your proposal — whether it’s hourly, recurring, or construction-based.

🧾 Summary

Step	Function	Output
1️⃣	Calculate base labor hours	How long the clean takes
2️⃣	Apply multipliers	Adjust for region, size, and complexity
3️⃣	Compute labor & area rates	Build the raw cost floor
4️⃣	Add all add-ons	Include pressure wash, windows, flooring, etc.
5️⃣	Select final bid type	Chooses between construction, T&M, or janitorial totals

In short —
💥 “The brain that processes everything” is the calculator’s master engine that unifies every input, applies smart scaling, and produces a realistic final bid across any cleaning scenario.
