Worked out from Texas Instruments BA II Plus guidebook, bond worksheet (printed pages 72-73 and 78) and 1 other source.
This prices to maturity. A callable bond can be redeemed early, and its yield to worst is not calculated here.
Current yield is quoted against the clean price, which is US market practice; some sources quote it against the settled dirty price.
A valuation from the figures entered, not a quote. Real prices depend on credit, liquidity and the day count a market actually uses.

How this is worked out

4 steps
  1. Coupon = 1000 × 5% ÷ 2 = 25 each period
  2. Yield per period = 6% ÷ 2 = 3%
  3. 10 coupon(s) and the redemption, valued at the next coupon date = 986.0695
  4. On a coupon date nothing has accrued, so clean and dirty are both 957.35
