Social Security Tax Liability over first $18000 limit

[dogmaii]

Question: 

My monthly SS payment will be Estimate $3000 per month which is $36000 a year. I am reading that I will be taxed as income on > $18000, so what is my tax liability and what rate??. So I am guessing $18000 taxable?

I will also be receiving a $750 pension which i plan to deduct $250 to pay taxes, leaving me with $500 extra income.  Does that get added to my SS Income?  and is that taxed on $36000 or added to $18000 SS income that is taxable ?

Is there a product or calculator that can help me??. 

So basic question is:  Will i get taxed on  $18000 SS Income on my yearly SS income of $36000 income or is it another amount??.

Medicare question - my last 2 years of work I will make >$120k so I see from their table I will be paying at least $300 per month in Medicare Costs.  Does the $300 per month REDUCE my taxable SS Income?? 

Thank you

Up to 85% of the SS benefits will be taxable depending on your other income. 

I will also be receiving a $750 pension which i plan to deduct $250 to pay taxes, leaving me with $500 extra income.  Does that get added to my SS Income?  and is that taxed on $36000 or added to $18000 SS income that is taxable ? 

ALL of your income is reported on the income tax return along with all the withholdings.  Then the taxable portion of the SS benefits is calculated. 

Is there a product or calculator that can help me??.
