§03Practical Example

Step-by-step walkthrough

Scenario

Apply the formula to a realistic set of inputs: Face value ($) = 1000, Coupon rate (%) = 5, YTM (%) = 6, Years = 10.

  1. 01Start by noting the input — Face value ($): 1000.
  2. 02Start by noting the input — Coupon rate (%): 5.
  3. 03Start by noting the input — YTM (%): 6.
  4. 04Start by noting the input — Years: 10.
  5. 05Substitute these values into the formula: l+=t / (1+n / 100)^(r),l
  6. 06Compute Price: the calculator returns 926.399.
  7. 07Cross-check the answer by opening the Derivation panel above — every line of math is shown so you can follow the computation end-to-end.

Common Bond Price Problems

The formula gets rearranged depending on which variable you need. Here are the patterns you’ll run into in the real world — find the one that matches your problem and follow the worked steps.

01 · PATTERN

Face value ($) halved

FV = 500 (from 1000)

Keep every other input at its default and halve the face value ($). See how price responds.

  1. 01New Face value ($): 500
  2. 02Baseline Price: 926.399
  3. 03New Price: 463.2
  4. 04Price decreases by 50% → use this sensitivity to plan for real-world variation.
02 · PATTERN

Face value ($) doubled

FV = 2000 (from 1000)

Keep every other input at its default and double the face value ($). See how price responds.

  1. 01New Face value ($): 2000
  2. 02Baseline Price: 926.399
  3. 03New Price: 1852.8
  4. 04Price increases by 100% → use this sensitivity to plan for real-world variation.
03 · PATTERN

Coupon rate (%) halved

coupon = 2.5 (from 5)

Keep every other input at its default and halve the coupon rate (%). See how price responds.

  1. 01New Coupon rate (%): 2.5
  2. 02Baseline Price: 926.399
  3. 03New Price: 742.397
  4. 04Price decreases by 19.9% → use this sensitivity to plan for real-world variation.
04 · PATTERN

Coupon rate (%) doubled

coupon = 10 (from 5)

Keep every other input at its default and double the coupon rate (%). See how price responds.

  1. 01New Coupon rate (%): 10
  2. 02Baseline Price: 926.399
  3. 03New Price: 1294.4
  4. 04Price increases by 39.7% → use this sensitivity to plan for real-world variation.
