Numbers get attention. "Increased sales" is forgettable. "Increased sales by 23% in Q3" shows impact. Here's how to add metrics to your resume.
Use the Formula: Action + Result + Number
Start with a strong verb, describe what you did, then add the outcome. Example: "Reduced customer wait time by 40% by implementing a new ticketing system."
Think in Multiple Categories
Revenue, cost savings, time saved, headcount, percentages, scale (e.g., "managed $2M budget"), and frequency (e.g., "processed 500 orders/day").
Estimate When You Don't Have Exact Numbers
Approximations are fine if reasonable: "Reduced onboarding time by an estimated 50%" or "Supported 20+ clients monthly."
Even Non-Quant Roles Have Numbers
HR: "Reduced turnover by 15%." Design: "Led 8 product launches." Support: "Handled 100+ tickets/week with 95% satisfaction."
Don't Oversell
Be honest. If you're unsure, round conservatively. Interviewers may ask for details.
