If you are unsure of what a field means, hover your mouse over it. An explanation
will appear in the box at the bottom of the calculator.
The calculator will automatically display a result when all fields contain
some value. (This is true even if you've only entered the first of two
or more digits in the last field. Don't worry, it will recalculate the
result as you add more digits.)
When you change a number, the calculator will automatically recalculate
The cost of the ads has already been subtracted. The campaign is profitable
if the result is greater than zero. (It appears in green for a profit,
red for a loss.)
Some percentages should not be over 100. If you ignore a warning about
a percentage value being too high, the calculator will still work but the
result may not be meaningful.
Don't evaluate an ad campaign solely on the results from this calculator. Note
the caveats below.
This calculator should be only a starting point for evaluating campaigns.
It can underestimate or overestimate campaign profits/losses for many reasons,
This calculation assumes only one sale and can, therefore, greatly underestimate
the profitability of an ad campaign. A new customer may become loyal. He
or she may make several purchases over time as a result of a single ad
exposure. To compensate, consider using an estimate of customer lifetime
value in the "Average Sale" field.
Your ad will create brand awareness that may not trigger an immediate response
(a click-through). If so, you will not count it as a click-through nor
attribute a subsequent sale to the Web ad campaign. However, that ad exposure
may contribute to a prospect's response through another channel. Had they
not become familiar with your brand through the original ad, they may not
have been significantly motivated to act through the second channel. If,
because of the low attributed click-through and conversion rates, you decide
to discontinue a Web ad campaign, you may find that sales through other
channels also drop in response to the lower brand exposure.
The corollary to the previous point is that some click-throughs and conversions
to sales are supported by brand awareness created through other channels.
Since this calculator does not include the cost of those exposures through
other channels, it may underestimate the cost of winning click-throughs
