About Break Even Inflation Rate Calculator

Break-even inflation is the rate at which a nominal bond and an inflation-linked bond of the same maturity deliver the same return. It is the market's implied inflation expectation plus an inflation risk premium.

Formula

Break-even inflation

Break-even = (1 + nominal yield)/(1 + real yield) - 1

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 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.

Frequently Asked Questions

Is break-even inflation a forecast?

It is a market-implied expectation, but it also contains liquidity and risk premia, so it is a biased forecast.

When do linkers outperform?

Whenever realised inflation exceeds the break-even rate over the holding period.
