About this calculator
The nominal (annual percentage) rate is the stated rate before accounting for compounding within the year, while the effective annual rate reflects what actually accrues after compounding m times per year. The two are linked by i_nom = m·[(1+i_eff)^(1/m) − 1].
Regulators typically require lenders and account providers to disclose both figures so borrowers and savers can compare products that compound at different frequencies — monthly versus daily, for instance — on equal footing. This calculator is used by finance students, loan shoppers, and analysts converting between a quoted rate and its true annual equivalent.
