Daily Interest Calculator — FAQs
Does daily compounding beat monthly?
Marginally — 5% APR compounds to 5.127% daily vs 5.116% monthly. The rate matters far more than the compounding frequency.
Is APR the same as the daily rate?
The daily periodic rate is APR/365 — but check whether your account quotes APR (simple) or APY (includes compounding).
