Run your numbers

Two ways in, same engine. Type percentages as plain numbers (30 means 30%). Nothing you type leaves this page.

I need $X more revenue a month. How many calls a day is that?

Show the math
Mode A (revenue to calls)
customers_needed          = rev_target / deal_value
held_qualified_needed     = customers_needed / close_rate
booked_qualified_needed   = held_qualified_needed / show_rate
booked_per_day_required   = booked_qualified_needed / selling_days
close_needed_at_7         = customers_needed / (7 x selling_days x show_rate)

Mode B (calls to cost and return)
Q                         = calls_per_day x selling_days
total_booked              = Q / qual_rate
leads                     = total_booked / book_rate
ad_budget                 = leads x cpl
cost_per_qual_booked      = ad_budget / Q
held_qualified            = Q x show_rate
cost_per_held_qual        = ad_budget / held_qualified
new_customers             = held_qualified x close_rate
new_revenue               = new_customers x deal_value
revenue_per_ad_dollar     = new_revenue / ad_budget   (first contract only)
value_per_held_qual       = deal_value x close_rate x margin
value_to_cost_ratio       = value_per_held_qual / cost_per_held_qual
show_point_value          = Q x 0.01 x close_rate x deal_value
book_point_saving         = ad_budget - (Q / (qual_rate x (book_rate + 0.01))) x cpl
calls_on_calendar_per_day = total_booked / selling_days
calls_per_day_affordable  = (budget_cap / cpl) x book_rate x qual_rate / selling_days
max_cpl_for_target        = budget_cap x book_rate x qual_rate / Q
