Return on TIPS Calculator
Treasury Inflation-Protected Securities (TIPS) are government bonds designed to protect investors from inflation. They provide a return composed of a fixed interest rate plus an adjustment for inflation. Calculating the Return on TIPS helps investors understand the real gain on their investment after accounting for inflation protection. This calculator simplifies determining the total return including both interest earned and inflation adjustments.
Formula
Return on TIPS is calculated as:
Return on TIPS = ((Interest Earned + Inflation Adjustment) ÷ Principal Amount) × 100
Where:
- Interest Earned is the fixed interest payment received from TIPS.
- Inflation Adjustment is the increase in principal due to inflation (measured by CPI or relevant index).
- Principal Amount is the initial investment amount.
How to Use
- Enter the interest earned from your TIPS investment.
- Enter the initial principal amount invested.
- Enter the inflation adjustment amount applied to your principal.
- Click “Calculate.”
- The calculator will display the total Return on TIPS as a percentage.
Example
Suppose you invested $10,000 in TIPS. Over one year, you earned $150 in interest, and your principal was adjusted upward by $100 due to inflation.
Return on TIPS = ((150 + 100) ÷ 10,000) × 100 = 2.5%
This means your TIPS investment returned 2.5% total, including inflation protection.
