About This Tool
Interest Calculator calculates simple interest or compound growth at yearly, half-yearly, quarterly, or monthly frequency. Simple: I = PRT/100. Compound: A = P(1 + R/(100n))^(nt), with n selected from 1, 2, 4, or 12.
What You Can Do
Transparent method
Simple: I = PRT/100. Compound: A = P(1 + R/(100n))^(nt), with n selected from 1, 2, 4, or 12.
Input-driven result
Interest Calculator uses principal, annual rate, period in years, interest type.
Result interpretation

- 4
Treat the result as a fixed-rate scenario that excludes fees, taxes, deposits, and withdrawals
Treat the result as a fixed-rate scenario that excludes fees, taxes, deposits, and withdrawals.
Practical Use Cases
Interest Calculator scenario comparison
Compare how changes to principal, annual rate, period in years, interest type affect the interest and accumulated amount.
Arithmetic check
Use Interest Calculator to reproduce the documented formula with values you can independently verify.
Privacy and File Processing
Interest Calculator keeps its Principal, Annual rate, Period in years, or Interest type input in browser memory while the operation runs. The workflow creates Interest and accumulated amount for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.
