Price Increase Impact Simulator

Before you raise prices: how much client attrition would actually erase the gain, and how much profit is on the table if fewer clients leave than that.

Net positive$29,250 profit change
New revenue$513,000
New gross margin39.8%
Break-even attrition18.6%
How we got here
  1. New revenue = current revenue × (1 - attrition) × (1 + increase) = $513,000
  2. Break-even attrition = increase / (increase + margin) = 8.0% / (8.0% + 35.0%) = 18.6%

Methodology

Formula: a price increase doesn't raise the cost of serving a retained client, so break-even attrition = price increase % / (price increase % + gross margin %). Losing a client removes both their revenue and the cost of serving them, only the retained clients' higher price is pure margin gain.

Assumption: gross margin is your average across all jobs, the same non-persisted assumption used in Overhead Allocation & Break-Even Revenue.

Limitation: assumes cost to serve scales only with client count, not with price, and treats attrition as an instant, one-time event rather than a gradual drift over the following year.
