"My Name Is Not Susan" performed moderately well on the charts in the countries it charted. In the US, it debuted at number 67 on the
Billboard Hot 100 for the week of July 27, 1991 and peaked at number 20 on September 7 in its eighth week. It would become Houston's 15th top 20 hit on the chart. It dropped out of the charts after ten cumulative weeks in total, at the time, Houston's shortest showing on the
Billboard Hot 100. It spent six of its ten weeks inside the top 40. It fared better on the
Hot R&B Singles chart. After debuting at number 68 on the chart for the week of July 27, it reached its peak of number eight on September 21. Its tenure on the R&B chart lasted 14 cumulative weeks. On the
Cash Box charts, its peaks there were number 27 and 9 on their pop and R&B charts respectively. The song also briefly charted on the
Adult Contemporary Singles chart, peaking at number 44, Houston's second lowest peak on that chart (her rendition of the
"Star-Spangled Banner", which also charted that year, was the lowest at number 48). It was among one of writer
Eric Foster White's first chart hits. Around the same time, he had also made the charts with R&B group
Hi-Five's pop-soul ballad, "
I Can't Wait Another Minute", to which he also produced. Globally, the song received an even more modest reception. In Canada, the song missed the top 40 entirely, reaching number 43, becoming Houston's lowest-charting single at the time. In Australia, it peaked at number 118. The song fared better in European countries: besides a peak of 43 in Belgium, it peaked at number 14 each in Finland and Ireland, in Luxembourg, it peaked at number 18. The song barely missed the top 20 on the Netherlands' Dutch Top 40 at number 22 while its peak on the country's Single Top 100 was number 28. In the UK, it also performed modestly well, peaking at number 29 on its
official singles chart, while peaking at number 25 on its
dance chart while peaking at number three on the UK Airplay chart. It charted twice in Germany, initially peaking at number 57. Seven years later, in 1998, a remixed version of the song (remixed by
Snap! in 1991 as the '70s Flange Mix), sent the song to a new peak at number 52. It reached the top 30 on the
Eurochart Hot 100, peaking at number 26. == Live performances ==
