Budget Allocation Scenarios
Part of the Digital Marketing Roadmap
In short
'You have ₹5 lakh for a quarter. How would you spend it?' Splitting it evenly is the weakest answer. Show reasoning, a test budget and how you'd move money as data comes in.
'You have ₹X, how would you spend it across channels?' — testing structured, evidence-based prioritization rather than an arbitrary even split.
Think of it like this
Pocket money in jars
A hostel student splits monthly money into jars: mess and rent first, travel next, a small jar for trying new things, and a bit saved for emergencies. Mid-month, if travel overflows, they shift money. Marketing budgets work the same way: essentials, tests, buffer, and regular rebalancing.

The big ideas
What you need to know
Goal and target CPA
Start with what success looks like: target CPA or ROAS. Allocation follows from that.
Use past data
Ask what's worked before. Proven channels get the base budget.
Keep a test budget
Reserve a slice for new channels or creatives so you keep learning.
Rebalance on a schedule
Review weekly or every two weeks and move money to what hits the target.

A quick CPA check by channel. Channels under target can take more budget; those over target need fixing or less money.
Save yourself the pain
Common mistakes
Oops
Splitting the budget evenly across every channel.
Do this instead
Weight it by evidence and goals, and explain why.
Oops
Setting the split once and never changing it.
Do this instead
Describe a review rhythm and the rule you'd use to move money.
Your mission
Allocate a mock budget
Quick check
Target CPA is ₹500. Search is at ₹400 and Meta at ₹750 after two weeks. What's a sensible move?
