About Clear Loan Calculators
Free loan calculators built to make borrowing costs easier to understand.
Who publishes this site?
Clear Loan Calculators is published by TheRubiconShopUS. It provides four free calculators for student loans, personal loans, mortgages and auto loans. No registration, subscription, email submission or financial account connection is required.
What we aim to do well
Make the payment understandable, show the long-term cost, and give you the math and schedule needed to check the result. Each calculator includes extra-payment simulations, up to three side-by-side scenarios, a full amortization schedule, CSV export and a printable summary.
How the site was created
The software and educational content were created with AI assistance using ChatGPT Sites. Numerical examples were checked with a separate Python Decimal implementation. No licensed financial qualifications, professional financial review or government endorsement are claimed.
The tools use a fixed-rate monthly model with disclosed assumptions. Read the calculation methodology and test cases to understand the results and their limits.
Contact and corrections
Email rubiconshop213@gmail.com to report a calculation issue or suggest an improvement. Include the calculator name and a non-sensitive example. Please omit account numbers, addresses, credentials and private documents. No response-time promise is made.
Free access and funding
The calculators are free for visitors. The site currently has no ads, affiliate links, lender lead forms or third-party analytics scripts. It does not sell loan products or arrange loans. Hosting is provided through ChatGPT Sites; hosting availability and owner usage limits are governed by that service, and unlimited hosting is not promised.
