About Home Emergency Fund Supplies Calculator

The target is essential monthly outgoings times the months of cover wanted, and the funding time divides the shortfall by what you can put aside each month. Sizing the fund on essentials rather than total spending keeps the target achievable, since discretionary spending would be cut in a real emergency anyway.

Formulas

Target

Time to fund

  • In particular, this calculator does not take inflation, tax, fees or charges 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.
