Home Internet Bill Audit: Keep, Renegotiate, or Switch?
Most home internet bills hide router rental, promo expiry jumps, data-cap overage, and install fees. Enter your current plan and compare three honest paths over 12, 24, and 60 months.
Assumptions and limits are listed under each result. This tool gives estimates only — actual ISP pricing varies by region and promotion.

What this means for you
When each option wins
Keep is fine if…
- Your promo runs >12 more months
- You own your router (no rental line)
- No data-cap overage in last 6 bills
Renegotiate when…
- Promo expires within 3 months
- A competitor advertises in your ZIP
- Rental + post-promo > $20 above market
Switch when…
- Retention line refuses any discount
- Fiber is newly available at lower tier price
- 5-year gap > $400 net of install/ETF
Assumptions & limits tap to expand
- Estimates only. Real ISP pricing varies by region, address, and bundled services.
- Post-promo price assumed flat after promo expires; ISPs may raise rates further.
- Router purchase amortized as a one-time line, not depreciated.
- Switch hassle is your subjective opportunity cost (default 3 hrs × $25/hr).
- Taxes & fees assumed constant across options; in reality they may differ slightly by carrier.
- This tool does not factor in speed differences, reliability, or customer-service quality — see the comparison articles below for those.
