Investment Income Calculator

How to use the Investment Income Calculator

The Investment Income Calculator is free and runs entirely in your browser — no sign-up, and nothing you enter leaves your device. It opens pre-filled with a realistic example, so you can see how it works before replacing any figure with your own; the results update as you type. Press Calculate to refresh the result panel, or Reset to return to the example.

The inputs it asks for:

• Investment Amount — a dollar amount.
• Annual Yield — a percentage (enter 6 for 6%).
• Payout Frequency — choose one — Monthly, Quarterly, Semi-Annual, Annual.

The formula

Straightforward yield arithmetic: it applies the annual yield to your principal for the yearly income, then splits that evenly across the payout periods:

Annual income = Principal × Yield
Per payment  = Annual income ÷ payouts per year

Principal

the amount invested

Yield

the annual income rate — a bond coupon, dividend yield, or savings APY

payouts per year

monthly = 12, quarterly = 4, and so on

This is simple income only: it assumes the yield is paid out rather than reinvested, and that principal and yield stay constant. It's a snapshot of income, not a growth projection.

Worked example

Using the example values — Investment Amount $500,000.00, Annual Yield 4%, Payout Frequency Quarterly — the Investment Income Calculator returns a Income per Period of $5,000.00. It also reports Annual Income ($20,000.00), Monthly Equivalent ($1,666.67).
