How to use the Investment Calculator

  1. Enter your initial investment and monthly contribution.
  2. Set the investment horizon in years and your expected annual return.
  3. Optionally apply an annual step-up to your contributions (great for matching salary growth).
  4. Set capital gains tax to see after-tax value, and inflation for real (today's-money) value.
  5. Toggle 'Beginning of month' for annuity-due style contributions.
  6. Read the chart: yellow shows what you invested, green shows what your money grew into.

Compounding + consistency = wealth

Long-term investing rewards two simple behaviors: investing consistently and not interrupting the compounding. Both are easier with automation: a fixed monthly transfer to an index fund is the gold standard.

Step-up SIPs (raising your monthly contribution by 5-10% per year) can dramatically increase the final corpus without ever feeling like a sacrifice, because the increase usually matches your raises.

Always look at the inflation-adjusted FV. A $1M portfolio in 30 years sounds great, but at 3% inflation it has the purchasing power of about $412K today. Plan in real numbers.
