About these tools

Every auto calculator documents its formula, shows worked examples with real numbers, lists assumptions and limits, and answers common questions. Results update instantly as you type, and nothing you enter leaves your browser.

Start with the tool closest to your decision, then use the related links to test neighboring scenarios — comparing two or three paths beats trusting any single estimate.
