Investment Growth Calculator

Go beyond basic compound interest. This calculator adds inflation adjustment, tax estimates, and three return scenarios so you see realistic projections for your portfolio.

Why Realistic Investment Projections Matter

Most investment calculators show a single growth line — a smooth, optimistic curve. Real markets don't work that way. Returns fluctuate, inflation erodes purchasing power, and taxes take a portion of your gains. This calculator accounts for all three.

The three-scenario model — pessimistic, expected, and optimistic — shows you the range of possible outcomes based on market variability.
