Software, cloud & AI calculators
Cost and capacity estimates from the prices you enter. Provider price lists change often, so no prices are built in.
AI & LLM costs
- LLM Token Cost CalculatorEstimate what a large language model API costs from input and output tokens per request, your request volume and the per-million-token prices you enter.
- AI Chatbot Cost Forecast CalculatorForecast the monthly cost of an AI chatbot from conversations, messages, tokens per message, your token prices, fixed costs and monthly growth.
- AI Agent Hours Saved CalculatorEstimate the staff hours an AI agent or assistant saves each month, what that time is worth at your hourly cost, and the net value after AI spend.
- Cloud GPU Training Cost CalculatorEstimate the cost of a model training job from GPU count, run time, runs, your price per GPU-hour, a buffer for failed runs, storage and data transfer.
- AI OCR Page Cost CalculatorEstimate the cost of AI OCR and document extraction from pages processed, your price per 1,000 pages, reprocessing, human review and storage.
- Vector Database Cost CalculatorEstimate vector database size and monthly cost from vector count, dimensions, precision, metadata, index overhead, replicas, storage and query prices.
Capacity planning
- Database Storage Growth CalculatorProject database size months ahead from today’s size and a fixed GB-per-month or percentage growth rate, and see when it will reach a capacity limit.
- API Rate Limit Throughput CalculatorFind your real API throughput from a requests-per-minute limit, concurrent requests and latency, the concurrency needed to reach the limit, and batch time.
- Queue Worker Capacity CalculatorSize background job workers: jobs per hour they can process, utilisation at your arrival rate, workers needed for a target load and time to clear a backlog.
- Database Connection Pool Size CalculatorSize a database connection pool from peak queries per second and how long each holds a connection, split across app instances and checked against the server limit.
Cloud costs
- Cloud Storage Cost CalculatorEstimate a monthly object-storage bill from GB stored with up to two price tiers, data transferred out, and read and write request charges.
- API Gateway Request Cost CalculatorEstimate a monthly API gateway bill from request volume, a free allowance, two per-million price tiers and response data transferred out.
- Serverless Function Cost CalculatorEstimate a monthly serverless function bill from invocations, duration, memory, billing increment, request and GB-second prices, and free allowances.
- CDN Bandwidth Cost CalculatorEstimate a monthly CDN bill from traffic in up to four price regions, the per-GB price you pay in each, and HTTP request charges.
- Cloud Backup Storage Cost CalculatorEstimate backup storage and monthly cost from data size, daily change rate, how often you take full backups, retention days and dedupe or compression.
- Reserved Instance Savings CalculatorCompare on-demand with a 1- or 3-year reserved or committed price, including upfront payment, and find your savings and the break-even usage.
Project & pricing
- Software Project Estimate CalculatorTurn per-feature hour estimates into total effort, budget and calendar time, adding overhead for testing and management and a contingency for unknowns.
- Website Maintenance Pricing CalculatorPrice a website maintenance retainer from support hours and your rate, plus hosting, licences and yearly renewals with an optional markup on third-party costs.
Reliability
- Uptime SLA Downtime CalculatorConvert an uptime percentage such as 99.9% or 99.99% into the downtime it allows per day, week, month, quarter or year, in minutes and seconds.
- Error Budget CalculatorTurn an SLO into an error budget of allowed failed requests, and see how much is used, what is left and the burn rate so far in the window.
- P95 Latency CalculatorPaste response times to get the 95th percentile (or any percentile), p50 and p99, by the nearest-rank method or linear interpolation, with mean and max.
Web performance
- Image Compression Savings CalculatorSee how much bandwidth, money and load time compressing an image saves, from the original and compressed sizes and how often the image is loaded.
- Video Streaming Bandwidth CalculatorWork out the data a video uses per view and in total from its bitrate, length, share watched and number of plays, plus peak egress for concurrent viewers.
- Cache Hit Ratio CalculatorCalculate a cache hit ratio and miss ratio from hits and misses, and the average response time when hits and misses have different latencies.
