What you can do here

Periods are a count, not a percent

12 means monthly. 4 means quarterly. 1 means the effective rate equals the nominal rate.

The formula is the definition

Nothing is annualised by multiplying a monthly rate by 12. That product is the nominal rate you already typed.

12.68 is the check

Twelve percent with twelve compounds should read 12.68% after rounding to two decimals.

The sequence

How to use the Effective Annual Rate Calculator

  1. 1

    Copy the advertised yearly rate

    If the note says 12% per annum compounded monthly, type 12 and 12. Do not type 1.

  2. 2

    Count the compounds

    Monthly is 12, quarterly is 4, half-yearly is 2, daily is 365 if they truly compound every day.

  3. 3

    Compare EAR with a once-a-year deposit

    A 12% annual deposit and a 12% monthly deposit are not the same deal. The gap is this page’s result minus 12.

Worth knowing

  • Effective Annual Rate Calculator on Toolspire: EAR = (1 + nominal/periods)^periods − 1.
  • 12% compounded monthly is (1.01)^12 − 1, about 12.68%.
  • Compounding once a year makes EAR equal the nominal rate.
  • More compounds raise the effective rate. The nominal percent in the advert does not move.

Nominal is the label, effective is the year

Banks often quote a nominal yearly rate and then compound more than once. Each compound adds interest on interest inside the year, so a rupee grows by more than the printed percent. (1 + 0.12/12)^12 − 1 is the extra. This page does not know fees, tax or a premature-withdrawal penalty.

What is 12% compounded monthly as an effective rate?

About 12.68% a year. Each month multiplies the balance by 1.01, twelve times.

What if it compounds once a year?

The effective rate equals the nominal rate. Type 1 in the periods box.

Is EAR the same as APR?

No. APR is often a nominal or a fee-inclusive borrowing label. EAR here is only the compound-growth identity from the rate and the count you type.

Why not just multiply 1% by 12?

That product is 12%, the nominal rate. Effective rate compounds the 1% on the growing balance.
