Estimate how a proposed price change and demand response could affect profit after fixed monthly costs. This calculator helps you compare the current situation with a new pricing scenario using simple, transparent assumptions.
What This Calculator Estimates
This calculator estimates the effect of a pricing change on profit after fixed costs. It compares the current profit with a new scenario that changes both price and demand, which makes it useful for rough pricing strategy discussions.
Formula / Method Used
- Profit = (price - unit cost) x units sold - fixed costs
- New price = current price x (1 + price change)
- New units sold = current units sold x (1 + demand change)
- Break-even units = fixed costs / (selling price - unit cost)
Worked Example
If the current selling price is $45, unit cost is $18, fixed monthly costs are $12,000, current unit sales are 900, proposed price change is 6%, and estimated demand change is -5%, the calculator first computes current profit, then adjusts the price and estimated sales volume to compare the new profit scenario.
What the Result Means
Current profit shows what your present margin and unit volume are estimated to generate after fixed costs. New estimated profit shows the same profit logic under the new price and demand assumptions. Break-even units show how many units must be sold at the current price and cost to cover fixed costs.
Common Mistakes
- Using unrealistic demand change assumptions.
- Ignoring channel fees, refunds, or commissions.
- Assuming unit cost stays fixed when volume changes significantly.
- Focusing only on short-term profit without considering customer retention or brand effects.

Frequently Asked Questions
What does this profit maximizer calculator estimate?
It estimates current profit, a new profit scenario after a price change and demand shift, the profit difference, and break-even units.
What are break-even units?
Break-even units estimate how many units must be sold to cover fixed monthly costs at the current selling price and unit cost.
Why include both price change and demand change?
A higher or lower price can change unit margin and also affect sales volume, so both assumptions matter for profit planning.
Are these results exact?
No. Results are estimates only and depend on the demand response and cost assumptions you enter.
