How This Calculator Works

This calculator uses industry benchmarks to estimate how much you're spending on numbers that will never receive your message:

Invalid rate — Based on our analysis of millions of numbers, the typical unmaintained contact list has 20-30% invalid or inactive entries.
Waste calculation — Your cost per message multiplied by the estimated number of invalid sends, scaled to your campaign frequency.
Savings projection — After cleaning, your invalid rate drops to under 1% (our platform achieves 99.99% accuracy). The savings are the difference.

This doesn't even account for the reputational damage of high bounce rates or the opportunity cost of messages that could have reached real customers. See our data decay guide for a deeper analysis.
