How much should banks spend on promoting CD specials?

Banks should typically allocate a targeted, campaign-based budget for CD specials rather than a fixed annual percentage—aligning spend with rate sensitivity, desired deposit volume, and acceptable cost per funded certificate. The right investment level is one that produces profitable balances after accounting for interest expense, incentives, and marketing costs.

Key Factors That Influence CD Promotion Spend

Rate competitiveness: Higher rates often require less media spend, while modest rate advantages need stronger promotion to stand out.

Target audience: Existing customers typically convert at a lower cost than new prospects, allowing for more efficient campaigns.

Deposit goals: Short-term liquidity needs may justify higher spend, while long-term balance growth favors efficiency.

Channel mix: Owned channels lower cost per account, while paid media accelerates reach during competitive periods.

Operational readiness: Digital account opening and funding speed directly affect conversion and return on spend.

Margin tolerance: Marketing investment must be evaluated alongside interest expense to ensure net profitability.

A Practical Framework for Budgeting CD Campaigns

Rather than guessing, banks should treat CD specials as measurable acquisition programs with clear targets and guardrails.

Step-by-Step

Define the objective. Clarify whether the goal is rapid deposit inflow, balance stability, or customer acquisition.
Set a target cost per funded CD. Establish the maximum acceptable acquisition cost based on margin and term length.
Segment audiences. Separate campaigns for existing customers, local prospects, and digital-only audiences.
Allocate by channel. Prioritize owned channels first, then layer paid media to reach volume targets.
Test offers and messaging. Compare rate-led versus value-led messages to improve efficiency.
Monitor funding speed. Track time from application to funded certificate to identify friction.
Adjust in real time. Shift spend toward channels and segments producing the most profitable balances.

What Strong CD Marketing Performance Delivers
