How to Create a Marketing Budget Proposal: Worked Example and Template

Shusaku Yosa

マーケティング予算案の作り方|承認される予算書テンプレート付き

A marketing budget proposal connects a business objective to activity, cost and decision rules. Start with the new-customer revenue requirement, work backward to wins, opportunities and qualified leads, then check both total cost and sales capacity. A polished document cannot compensate for inconsistent assumptions.

The following fictional example uses Japanese yen for a business operating in Japan. It is a planning illustration, not a benchmark or a promised return.

Work backward from revenue

Assume an annual new-customer bookings target of JPY100 million, JPY2 million per won deal, a 20% opportunity-to-win rate and a 25% qualified-lead-to-opportunity rate.

Acquisition activity cost

JPY8m

Win rate and lead-to-opportunity rate have different denominators. Define a qualified lead consistently: for example, a contact from an eligible company, with usable contact information, excluding duplicates and existing customers. A cost per raw download cannot simply be substituted for cost per qualified lead.

This model assumes the acquired cohort can progress before the evaluation deadline. If qualification takes two months and closing takes another three, leads acquired near year-end cannot all support the same-year bookings target. Separate existing pipeline from newly generated demand and check the sales team's monthly follow-up capacity.

Reconciled scope without duplicate costs

If an agency quote includes production, do not add the same production cost again. Attach supplier quotes and comparable historical results, marking estimated quantities separately from committed prices. Revenue-percentage checks can test affordability, but no single percentage is optimal for every company.

The downside assumes the JPY11 million budget is still spent while acquisition efficiency and stage progression weaken. It reveals which assumptions matter. Lower lead volume calls for a different investigation from poor sales acceptance or declining win rate. Link each risk to an owner and a possible response rather than changing every tactic at once.

Distinguish ROI from ROAS

In a separate simplified example, JPY1 million in ad spend produces JPY10 million in attributed revenue, with a 50% gross margin before that marketing investment and no other marketing costs. ROAS is JPY10m / JPY1m = 1,000%. ROI is (JPY5m gross profit − JPY1m investment) / JPY1m = 400%.

“Ten times ad spend in revenue” describes ROAS. Google's ROI guidance distinguishes the revenue and cost components. For a real proposal, specify whether production, agency work and allocated labor are included. Do not subtract the investment twice from a profit figure that already includes it. Attributed revenue is also not proof of revenue caused by advertising.

Use a one-page approval summary

Field

What to write

Decision requested

JPY11m annual envelope, with agreed review conditions

Business objective

JPY100m in new-customer bookings; existing-customer revenue handled separately

Assumptions

JPY2m deal value, 25% qualification-to-opportunity, 20% win rate, with evidence

Accountability

Marketing owner, sales owner and cost reviewer

Alternatives

Narrow the market, retain the current approach, or change outsourcing scope

Risks

Follow-up capacity, rising acquisition costs and delayed sales cycles

Review date

A specific date allowing the acquired cohort to mature

Reconsideration rule

Reassess new spending if agreed cost, qualification or follow-up limits are breached

Agree on the observation window before launch. A slow sales cycle is not by itself a reason to stop an otherwise valid test, and insufficient data should be reported as insufficient data. Before submission, check the arithmetic, sales workload, cost scope, assumption sources and the person responsible for updating the forecast after approval.

Keep budgets and execution connected
