Compare assumptions, not offers
Results are deterministic browser-local math from the values you enter. They are useful for scenario comparison, but they are not a lender quote, approval decision, investment forecast, credit recommendation, or substitute for an account agreement.
How to use this Simple Interest Loan Calculator
Use P × r × t to calculate interest and total amount for a simple-interest scenario, with assumptions stated explicitly.
What this tool does
Calculate simple interest from principal, annual rate, and time without amortization or compounding.
Practical tips and limits
Results are mathematical estimates. Verify the interest method, payment timing, fees, and lender-specific rules in the actual loan agreement before relying on the result.
