In-depth explanation
Model long-term portfolio growth with monthly contributions and an expected annual return. Also shows an inflation-adjusted (real) value in today’s money. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
Long-run equity averages are often cited around 5–10% nominal before fees, but past performance is not a guarantee. Be conservative for planning. The projected balance adjusted for your inflation assumption — roughly what the money could buy in today’s prices.
Platform and fund charges reduce net returns — lower the expected return to approximate fees. Use Investment Growth Calculator for quick planning; confirm important money, tax, or health decisions with an official source or professional when needed.
