About Net Worth Growth Projection Calculator

Net worth grows from two engines: existing assets compounding and new savings added each year. Over long horizons the growth on existing assets dominates, which is why starting early matters more than saving harder later.

Formula

Net worth projection

Future = NW(1+r)^n + savings × [((1+r)^n - 1)/r] × (1+r)

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or fees or charges into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates for planning only. Prices, returns, inflation and personal circumstances all change. This is not financial or tax advice — speak to a qualified adviser before making decisions.

Frequently Asked Questions

Should the home be included?

Include it at market value less the outstanding mortgage, but remember it produces no income to live on.

What return should be assumed?

A blended real-world figure net of fees for your actual asset mix, not the best asset's historical return.
