Family Plans: How to Compare the Real Cost Per Line

Family plans are advertised in ways that make comparison hard. The fix is simple: work out the real monthly cost for your whole household, then divide by the number of lines.

Step 1: Total the monthly price

Add up the plan price for the number of lines you need. Note whether that price requires AutoPay or paperless billing.

Step 2: Add taxes and fees

Some carriers include taxes and fees in the price; others add them on top. This can change the total noticeably.

Step 3: Subtract real discounts only

Count discounts you will actually get every month. Treat limited-time promos and bill credits separately, and note when they end.

Step 4: Divide by your lines

That number is your true cost per line. Compare it across carriers.

Tips

• Not everyone needs the same plan — Some carriers let each line pick its own plan. A kid on Wi-Fi all day may not need unlimited.
• Check every person's coverage — The cheapest plan is no deal if one family member has no signal at work or school.
• Look past the first year — Intro pricing often ends after a few months.
