Established and widespread portfolio theory uses benchmarking to evaluate performance.  The above matrix can be used to benchmark your portfolio against a generic portfolio using the S&P 500 Index for the equity position and the Bloomberg US Aggregate Bond Index for the fixed income position for the desired timeframe period.  For example, if you were 100% invested in  equities for 2022 you would use column one and read down to the 100% row.  The matrix equity return for 2022 was -18.1% so that is what you would use to evaluate what your portfolio return was for the year.
