The 4% Rule

This image nails something marketers can steal: taking a complex idea (retirement math) and turning it into one easy formula anyone can get.

What’s Happening Here

The designer uses a simple rule of thumb — 4% — to instantly communicate a massive concept. Instead of graphs or jargon, it’s clean math and clear outcomes: “Need $50k a year? You’ll need $1.25M.” Bam. Instant clarity.

Why It Works

• Turns abstract fear (retirement) into a simple, solvable equation
• Uses one consistent variable to anchor the story
• Breaks steps into visuals that teach while they sell
• Offers immediate takeaway value audiences can apply instantly

Examples

• Buffer’s “Open Salaries” uses radical transparency to explain complex pay logic.
• HubSpot’s “ROI Calculator” simplifies marketing spend anxiety.
• Ramit Sethi’s “Conscious Spending Plan” follows the same idea: one formula, full clarity.
