Stress Test Loss Calculator

Work out stress test loss instantly with clear inputs, formula shown and shareable results.

About Stress Test Loss Calculator

Stress testing multiplies the baseline default rate by a severe but plausible factor and recomputes losses. The incremental loss above the baseline is what capital must absorb, since expected loss is already covered by provisions and pricing.

Formula

Stressed loss

Stressed loss = exposure × (baseline PD × multiple) × LGD

Worked example

With the default values below, Stress Test Loss Calculator returns Loss Under Stress of $21,600,000.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • 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, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates based on the inputs given. Bank charges, regulatory minima and market rates change and differ between institutions and jurisdictions. This is not financial advice — confirm with your bank or treasury policy.

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

Frequently Asked Questions

Why multiply the default rate?

Because recessions raise default frequency several-fold, and historical severe periods provide the multiple.

Should loss given default also be stressed?

Yes ideally — collateral values fall in the same downturn, so recovery rates deteriorate together with defaults.
