A common way of quoting a swaption price is referring to its 'implied volatility' rather than the price itself. The implied volatility for the swaption is the volatility parameter required in a benchmark pricing model, which allows for closed-form prices, for the modelled price to replicate the market price of the swaption. The benefit of this method of quotation is that it removes the effect of the parameters not related to volatility that are contributing to the swaption price, such as the underlying yield curve, its strike, maturity, and tenor.
