How it works

Three honest numbers from what you actually do, plus one estimate you control.
1. Your real habitHow many images you keep a week, and how many tries it takes to land one.
2. Your real costYour price per image or your monthly plan, plus the minutes each try costs you and what your time is worth.
3. The leakThe money and hours that go into throwaway re-rolls, then an estimate of what fewer re-rolls would save.

Questions

How does this AI image cost calculator work?
You enter how many good images you keep per week, how many generations it takes to land one, your cost per image or monthly plan, and the minutes and hourly value of your time. It multiplies those out into money per month, the spend wasted on regenerations, and the hours lost, all live in your browser. Nothing is sent anywhere.
Is the savings number a real promise?
No. The savings figure is a clearly labeled estimate based on the percentage you choose for fewer re-rolls. It shows what landing images in fewer tries could save, not a guarantee. The wasted spend and wasted time above it are exact math from the numbers you type in.
Does my data leave my browser?
No. The calculator is 100 percent client-side vanilla JavaScript. Your numbers never leave your device, there is no signup, and nothing is stored or logged.
