A bond's price is the present value of its coupons and face value, discounted at the yield. Price moves inversely to yield along a convex curve. Duration measures that sensitivity — a modified duration of 8 means roughly an 8% price drop per 1% rise in yield. Educational tool, not investment advice.

Governing equation

P = t = 1 \sum 20 \frac{25.00}{( 1 + 0.0200 ) ^{t}} + \frac{1000}{( 1 + 0.0200 ) ^{20}} = $1081.76

Reading this result: The coupon beats the 4.0% yield, so the bond sells at a premium — about 8.2% over par — and its 7.9 modified duration is the % price drop per +1% yield.
