How many leads do I need per month? How to calculate it

Work out how many leads to buy per month from your sales target, conversion rate and average deal size.

Buying leads// PRACTICAL GUIDE

"How many leads do I buy per month?" The answer is not a random number: you calculate it from your sales target, working backwards through the funnel. Here is the math.

Work backwards from your goal

Start with how many new customers you need per month. Then apply your conversion rates stage by stage to find how many leads you need at the top.

  1. Goal: new customers per month (e.g. 10).
  2. Close rate on qualified lead (e.g. 20%).
  3. Qualification rate on contacted lead (e.g. 40%).
  4. Contact rate on bought lead (e.g. 70%).
Con el ejemplo: necesitas 10 clientes ÷ 20% = 50 cualificados; ÷ 40% = 125 contactados; ÷ 70% ≈ 180 leads comprados al mes. Ajusta con tus tasas reales.

If you do not know your rates

Start with a small pack, measure your real rates and recalculate. It is better to calibrate with data than to guess. Rates improve if you buy higher-intent leads and improve response speed.

Quality before quantity

Buying more leads is not always the answer. Sometimes, buying higher-intent and score leads reduces the volume needed for the same number of sales.
