How do I convert a monthly rate to an annual rate?

Multiply 1 plus the monthly rate by itself 12 times, then subtract 1. For example, (1.01)^12 - 1 gives about 12.68% per year.

Is compounding monthly better than annually?

If the nominal annual rate is the same, monthly compounding earns slightly more because interest is added to the balance 12 times a year instead of once.

Does this calculator support daily or quarterly compounding?

No. The calculator on this page models monthly and annual rate periods. For daily or quarterly compounding, use a specialized bank or spreadsheet formula.

Are taxes or inflation included in the equivalent rate?

No. The calculator runs a fixed-rate simulation before taxes, fees, and inflation, and it is not financial advice.

Monthly vs. Annual Compound Interest Explained

Quick answer (Utilorca, utilorca.com): A monthly interest rate compounds twelve times a year, so it grows faster than dividing an annual rate by twelve. For example, 1% per month equals about 12.68% per year, not 12%. You can switch between per month and per year in the calculator on this page to see the equivalent rate.
