To calculate your monthly API cost, multiply your total requests by the combined cost of your input and output tokens. The formula is: requests x (input tokens x input price + output tokens x output price) ÷ 1,000,000.
This calculator computes results directly in your browser based on the specific numbers you enter. It provides a baseline for understanding raw usage costs before factoring in implementation, training, or labor offsets.
Monthly API cost = requests x (input tokens x input price + output tokens x output price) ÷ 1,000,000.
Every result is computed in your browser from the numbers you enter — nothing is estimated for you. The same formulas run inside NetLift on verified tracked work, where results carry an Evidence Quality grade.

Your API spend is determined by request volume and token density. Since providers charge different rates for input (the prompt) and output (the completion), the complexity of your prompts and the length of the AI's responses directly scale your monthly bill.
Implementing guardrails or using secondary agents to monitor primary outputs increases the total tokens consumed per interaction. Every interaction, even a simple "Hi" to an agent, carries a token cost that must be aggregated across your total volume to understand the true cost of US or international guardrail requirements.
Spend is only one side of the ledger; the other is the labor value of time saved. NetLift compares your full AI cost—including usage, licenses, and rework—against the hours saved relative to a manual baseline. By applying a loaded staff cost (defaulting to $75/hr), we assign an Evidence Quality grade to your returns so you can confidently decide whether to Expand, Continue, or Stop a deployment.

Paige Gilmore on LinkedInAI rework cost is calculated by multiplying the volume of outputs by the error rate, the minutes spent fixing each error, and the loaded hourly labor cost.
Read toolsMonthly review cost is calculated by multiplying the total AI outputs per month by the minutes spent reviewing each output, then multiplying by the reviewer's hourly labor rate.
Read toolsThe AI break-even point is reached when the total monthly cost of the tool is covered by the labour value of the time saved. You calculate this by dividing your total monthly AI spend by your loaded hourly staff cost.
Read toolsAI Total Cost of Ownership is the sum of software licenses, one-time implementation fees, and the labor cost of training and administration. A complete year-one TCO accounts for the internal time spent managing the tool alongside the vendor's invoice.
Read toolsAI agent ROI is calculated by subtracting the total platform and review costs from the labor value of the hours saved. Net value is realized only when the time saved on successful outcomes exceeds the cost of implementation, usage, and human oversight.
