About Marriage Fund Planning Calculator

Wedding costs inflate faster than general prices, so the future figure is considerably above today's quotes. Crediting existing savings and their growth first gives the realistic monthly amount still required, assuming a 9% return.

Formula

Marriage fund

Future cost = today's cost × (1+inflation)^years; monthly = (future cost - grown savings) / annuity factor

Worked example

With the default values below, Marriage Fund Planning Calculator returns Monthly Saving Required of $34,289.38. Change any input above and every figure here is recalculated in your browser.

  • 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 tax or compounding frequency 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.
