overview
Agency media planning is broken. You are using last year's industry benchmarks, your senior strategist's intuition, and a spreadsheet template to allocate client budgets that total millions of dollars. The process takes days, requires constant revision, and produces recommendations that are already outdated by the time they are presented. The Marketing Budget Calculator generates AI-powered client budget recommendations in 20 seconds — with channel breakdowns, projected ROAS, waste estimates, and a prioritized action plan.
the solution
Generate AI-powered budget allocations for every client in seconds, with channel breakdowns, ROAS projections, and waste estimates tailored to each client's goals.
the problem
Agencies manage 20 client budgets with 2 analysts — and most budget recommendations are based on industry templates, not real-time performance data.
the problem
The agency budget planning problem
Most agency budget planning processes have three fundamental flaws: they are static (set once, reviewed quarterly), they are based on averages (industry benchmarks that may not reflect client-specific dynamics), and they are disconnected from real-time performance (last month's data informing next month's plan). The result is budget allocation that is consistently behind reality.
the solution
What agencies use the Budget Calculator for
The Budget Calculator is an agency's secret weapon for three scenarios: client onboarding (generate a preliminary budget plan before you have historical data), monthly planning (generate a revised allocation based on updated goals and performance), and client presentations (show data-driven budget recommendations instead of gut-feel allocations).

faq
Common questions from marketing agencies.
Can agencies use the Budget Calculator for prospecting?
Yes — this is one of the highest-ROI uses. Run a budget analysis for a prospect using their publicly available information (company size, industry, likely budget range). Walk into the pitch with an AI-generated budget plan that shows you have already done the strategic thinking. Close rates improve significantly.
How does the Budget Calculator handle different client industries?
The Budget Calculator is trained on benchmark data across 12+ industries. When you specify the client's industry, it applies the relevant benchmarks — e-commerce ROAS norms, B2B CAC expectations, SaaS payback periods. Each client gets an industry-appropriate allocation, not a generic template.
Can multiple team members use the Budget Calculator for different clients?
Yes — the free Budget Calculator is available to anyone without a login. For organized client management, team collaboration, and historical tracking across all clients, the Plexrio Agency plan provides a unified workspace.
How do we handle clients who want to override the AI recommendations?
The Budget Calculator generates a recommendation — the decision is always yours and the client's. Use the output as a starting point for the strategic conversation, not as a non-negotiable directive. The full Budget Brain platform allows you to set guardrails that reflect client preferences while still optimizing within those constraints.
What is the upgrade path from the free Budget Calculator to the full platform?
The free Budget Calculator generates a one-time recommendation. Plexrio Budget Brain monitors performance continuously, reallocates spend in real time, and fires automatic kill-switches when campaigns underperform. Agencies typically upgrade when they have clients spending $10k+/month on paid media where continuous optimization has clear ROI.
