How is the payment calculated?
For a fixed-rate loan with equal monthly payments, M = P × r ÷ (1 − (1 + r)−n). P is the principal, r is the annual interest rate (as a percentage) divided by 1,200, and n is the term in years multiplied by 12. At 0% interest, the payment is P ÷ n.
For example, $250,000 at 6.5% over 30 years is approximately $1,580 per month, rounded to the nearest dollar. This estimate includes principal and interest only. Taxes, insurance, fees, and lender-specific terms are excluded.

Is AyeCalc really free?
Yes. All calculators, converters, image tools, developer utilities, and guides are free to use. You do not need an account or subscription.
What happens to my files and inputs?
Calculations and supported image processing happen in your browser. Some tools download a processing library or AI model before running locally. Each tool explains its network requirements and limitations, and our privacy policy describes how the site handles data.
Can I use these tools on my phone?
Yes. The tools are designed for phones, tablets, and desktop browsers. Some image and AI tasks need a recent browser and enough device memory; individual tool pages explain any requirements.
How do I know what a result means?
Tool pages explain their formulas, settings, examples, and limitations. Loan payments are estimates, and image analysis provides evidence rather than certainty. Check the method and assumptions before relying on a result.
