I'm not sure how you got this calculation.

Suppose I'm considering a mortgage of 100K.

If rates go from 1% to 2%, my payment goes from 322 to 370, an increase of ~15%.

If rates go from 6% to 12%, my payment goes from 600 to 1029, an increase of ~71.5%.

Massive difference in terms of affordability.
