Every point reprices all 5 active services against plan allowances and overages; it does not simply multiply today's bill.

Growth verdict
The known stack is $325/month today and $2,935/month at 10× usage. Vercel Pro first changes from Hobby to Pro at 2× workload. Every active line has a numeric estimate.
AI models use separate input and output token rates. Email APIs use send allowances and overages. Authentication uses active users, while storage, bandwidth, events, seats and compute retain their own units. PriceIndex never converts one workload unit into another.
After each line is priced in monthly USD, known costs can be added. Custom quotes remain visible but outside the numeric total. Taxes, optional add-ons, negotiated contracts and untracked meters can still change the final invoice.
The forecast applies 2×, 5× and 10× workload to every active line, then runs plan selection again. That preserves free tiers, included allowances, minimum fees and step changes between plans.
Open the LLM Token Calculator, Email Pricing Estimator, or any linked service calculator for deeper comparisons. Read the pricing methodology and track changes in the AI Model Price Index and APIs Price Index.
Add each service, enter its real monthly workload and combine the resulting dollar estimates. PriceIndex calculates every line in its native unit first — such as tokens, emails, monthly active users, seats or GB — then adds only known monthly USD costs.
Yes, but their raw usage is never compared. Each service is priced independently in its own published billing unit. Only the resulting monthly dollar estimates are combined into the stack total.
AI cost equals requests multiplied by input and output tokens per request, with each token total charged at the model's listed per-million-token rate. Input and output remain separate because their prices often differ substantially.
The line is marked Custom and excluded from the known total. It is also counted separately so the displayed total cannot be mistaken for a complete quote.
Plan allowances, free tiers, minimum fees and overage bands change as usage grows. Every growth point is recalculated against the available plans instead of multiplying the current invoice.
No. Taxes, negotiated contracts, optional add-ons and untracked meters can change an invoice. Use the linked provider calculators and official pricing pages to review plan-specific details before purchasing.
