Profit Margin on a Bid

Excel Formulas › Cleaning & Janitorial

All versions

A bid’s profit margin is price minus all costs, over price. Pricing from a target margin — cost divided by (1 − margin) — guarantees the markup instead of guessing.


Quick formula: bid price for a target margin:
=total_cost / (1 - target_margin)
Divide total cost (labor + supplies + overhead) by one minus the target margin to set a price that hits it.

The example

$120 cost, 40% target margin.

AB
1ItemValue
2120 / 0.60—
3Bid price→ $200

The formula

The formula:

=total_cost / (1 - target_margin) // cost ÷ (1 − target margin)

How it works

How it works:

  1. Total the cost: burdened labor + supplies + allocated overhead.
  2. Divide by (1 − target margin) for the price that yields that margin.
  3. Margin % = (price − cost) ÷ price — check it after.
  4. Don’t confuse margin and markup: a 40% margin is a 67% markup on cost.

Margin and markup are not the same — pricing on the wrong one loses money. A 40% margin means cost is 60% of price (divide by 0.60). A 40% markup means price is cost × 1.40 — only a 28.6% margin. Cleaners who “add 40%” thinking they’re getting a 40% margin quietly under-price every job. Price from margin with cost ÷ (1 − margin) and the markup takes care of itself.

=(price - total_cost) / price

Markup equivalent

On cost:

=target_margin / (1 - target_margin)

=price - total_cost

Pitfalls & errors

Margin ≠ markup. Price from margin: cost ÷ (1 − margin).

All costs. Burdened labor + supplies + overhead, not just labor.

Margin of 100%. Dividing by zero (margin=1) errors.
