Real GDP

Nominal GDP/GDP Deflator x 100

Nominal GDP

real gdp*GDP deflator/100

Exact annualized growth

(1+quarterly rate)^4-1

Approx annualized growth

Q rate*4

(1+Nominal GDP growth/1+inflation)-1

Approx growth from nominal gdp growth

Nominal growth-inflation

How repurchased agreements(repo) works

(amount received- amount paid)/amount paid*100

Simple loan

loan value=amount paid/(1+i)^n

Fixed payment loan

loan value=fixed payment/(1+i)^n......

Coupon Bond

coupon payment/(1+i)^n.....last one add face value to top

discount bond

present value of bond=F(mature price)/(1+i)^n if one year (F-P)/P
