Budget Planning

Advertising Budget Calculator for Sri Lankan Businesses

Most Sri Lankan businesses underspend on marketing — or worse, spend the wrong amount on the wrong channel. Here is how to set a realistic, defensible budget.

Method 1 — Percentage of revenue

Business stage% of revenueStrategic intent
Startup / launch15–25%Aggressive — build initial awareness
Growth (1–3 years)10–15%Scale what already works
Established5–10%Defend market share, stay top of mind
Mature market leader3–6%Brand maintenance and innovation

Method 2 — Objective-based (CPL × leads needed)

Required revenue ÷ average order value = customers needed ÷ close rate = leads needed × CPL = monthly budget.

  • Example: Rs 5M revenue ÷ Rs 25,000 AOV = 200 customers
  • 200 customers ÷ 20% close rate = 1,000 leads needed
  • 1,000 leads × Rs 350 CPL = Rs 350,000 monthly ad budget

Recommended channel allocation by goal

Primary goalDigitalTraditionalBTL / Events
Online sales or leads75%10%15%
Local brick-and-mortar footfall45%30%25%
National brand awareness35%45%20%
B2B services60%30%10%

Always reserve a test budget

  • 70% on proven channels (with monthly performance reviews)
  • 20% on testing new creative or audience segments
  • 10% on entirely new channels and experiments

If you cannot measure CPL or CAC for each channel, you do not have an advertising budget — you have an expense.
