Chapter 01— Overview
Making fixed-income wealth building accessible to everyday investors.
Bonds and fixed-income debt securities are among the most reliable wealth generation tools, yet retail investors have historically found them intimidating due to confusing calculations (YTM, coupon frequencies, accrued interest, and tax deductions).
Tuntun Bonds was designed as an intuitive gateway that translates complex bond mathematics into clear, projected passive income streams.
Chapter 02— The Challenge
Conveying yield curves and maturity dates without overwhelming retail users.
Unlike stocks where price per share is straightforward, bonds require investors to grasp Coupon Rate vs Yield to Maturity (YTM), secondary market liquidity discounts, and settlement timelines.
Our challenge was designing interactive calculators that allow investors to visualize their exact monthly cashflow payout schedule with a single slider adjustment.
“Financial clarity creates investor courage. When users see their exact future cashflow calendar, bond investing feels rewarding and secure.”
