Under the hood, Interest-Only Loan Calculator uses standard amortization formula fed by loan amount, interest rate, term. Interest Rate Shock uses linear scale factor or affine conversion fed by source value and source unit. The two are not substitutes; they answer adjacent questions in your workflow.
Pick Interest-Only Loan Calculator when your question is about interest-only loan and your inputs are loan amount, interest rate, term. Pick Interest Rate Shock when the question shifts to interest rate shock and your inputs become source value and source unit.

Interest-Only Loan Calculator is designed to answer questions about interest-only loan using loan amount, interest rate, term. Interest Rate Shock is designed for interest rate shock using source value and source unit. They are complementary tools that target different inputs and outputs.
Use Interest-Only Loan Calculator when your task is generic loan payment and you need a monthly payment, total interest paid from loan amount, interest rate, term.
Use Interest Rate Shock when the question is interest rate shock estimate and decision support and your inputs are source value and source unit. The result is a interest rate shock result, derived from the inputs above.
Yes. Both run entirely in your browser, require no login, and are free to use without limits. Your inputs are not transmitted to any server.
Accuracy depends on the inputs you provide, not on the tool. Interest-Only Loan Calculator uses standard amortization formula and is accurate for interest-only loan when its inputs are correct. Interest Rate Shock uses linear scale factor or affine conversion and is accurate for interest rate shock under the same condition.
