This is the estimation I did some time ago.

Estimation of your SN benefit is around $53000 for the two of you, if you both retired (this is rough estimation only).

The calculation of additional tax, caused by SS benefit, is given in the following site.

I assume 28% highest tax bracket for your family.  Note:  This is your highest tax bracket, not the effective tax bracket. For most of the engineers, 28% is reasonable.

Here is how much the additional tax caused by SS benefit.

If you got 64K in other income, 85% of SS is taxed. (pay $12600 for SS benefit alone)/This is the maximum tax you can pay  on SSN benefit

If you got 60K in other income, 80% of SS is taxed. (pay $11795 for SS benefit alone)   ($2380 more than line below)

If you got 50K in other income, 63.4% of SS is taxed. (pay $9415 for SS benefit alone)

If you got 40K in other income, 47.4.4% of SS is taxed. (pay $7035 for SS benefit alone)

If you got 30K in other income, 31.4% of SS is taxed. (pay $4655 for SS benefit alone)

If you got 20K in other income, 15.3% of SS is taxed. (pay $2275 for SS benefit alone)

If you got 10K in other income, 4.2% of SS is taxed. (pay $630 for SS benefit alone)

If you got 00 in other income, 0% of SS is taxed. (pay $0 for SS benefit alone)

This means, for the extra $60K you had for the additional  income (other than SN benefit), you are going to not only pay the 28% income tax on the 60K, you will also have to pay the additional $11795 on the SSN benefit. This means your effectively tax rate for the additional income, of 60K,  is 28% + 19.65% = 48%. Or, in another word, for the addition $60K you get, you can only keep less than $32K.
