SEO tool pricing is deliberately confusing. Every vendor lists a headline price, then the real cost climbs with projects, tracked keywords, user seats, and add-ons. This page cuts through it: enter how many sites and keywords you actually need, and the calculator shows the cheapest plan from each tool that genuinely covers you – plus the true cost per client. No headline-price games. Prices verified June 2026 against official subscription pages.

How the four tools differ on price

Mangools – cheapest, but capped

At $44.90/month, Mangools is the cheapest genuinely capable toolkit. The trade-off is scale: the Basic plan tracks just 200 keywords, so it suits solo bloggers and freelancers with one or two sites rather than agencies. Read our full Mangools review.

SE Ranking – the value sweet spot

SE Ranking Core at $103.20/month tracks 2,000 keywords across 10 projects and includes white-label reporting, features SEMrush charges extra for. For freelancers and small agencies, the per-client cost drops fast as you add sites, which is why it usually wins the calculator above. See the SE Ranking review or the full SE Ranking pricing breakdown.

Ahrefs – priced for backlink work

Ahrefs Lite at $108/month is competitive on paper, but it has no free trial and its credit-based limits on lower tiers frustrate heavy users. It’s worth the price specifically for backlink analysis depth. Read our Ahrefs review.

SEMrush – most powerful, watch the add-ons

SEMrush Pro at $117.33/month is the most feature-rich entry plan, with unmatched PPC and content research. The catch: extra user seats cost $45/month each and white-label reporting requires a higher tier, so the real agency cost climbs quickly.
