Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Does certification mean permanent change?

No. Slippage back to open defecation is common, so verification and post-certification follow-up are part of the process.

Why community-level certification?

Open defecation harms everyone nearby, so the health benefit depends on whole communities changing behaviour rather than individual households.
