Bond Price Change from Duration: Estimate a bond price change from modified duration and a market-yield movement.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Bond Price Change from Duration to answer this question: estimate a bond price change from modified duration and a market-yield movement? Enter Current bond price, Modified duration, Yield change; the calculator shows Estimated bond price. Try changing one number and watch what happens to Estimated bond price. The answer tells you Estimated bond price.
Age 15Explain it to a 15-year-oldConnect it to the formula
The duration estimate is most useful for small, parallel yield movements and excludes convexity. The rule is Estimated percentage price change = −modified duration × yield change. Its input values are Current bond price, Modified duration, Yield change (%), and the main result is Estimated bond price. Try changing one number and watch what happens to Estimated bond price.
CollegeExplain it at college levelState the model precisely
This calculator evaluates a personal-finance model from stated cash amounts, rates and time assumptions. The implemented relation is Estimated percentage price change = −modified duration × yield change, evaluated from Current bond price, Modified duration, Yield change (%) to produce Estimated bond price. The duration estimate is most useful for small, parallel yield movements and excludes convexity. The result cannot predict markets or include unentered taxes, fees, legal rules, benefits, insurance terms or personal circumstances. Verify material decisions against current documents.
What this personal finance tool does
Estimate a bond price change from modified duration and a market-yield movement.
Why the relationship works
The duration estimate is most useful for small, parallel yield movements and excludes convexity.
The formula
Estimated percentage price change = −modified duration × yield change
Inputs and time periods
This model uses Current bond price, Modified duration, Yield change. Keep currencies and time periods consistent, and distinguish current known amounts from assumptions about future rates.
What the result means
The primary output is Estimated bond price; supporting outputs include Estimated price change, Estimated value change. Compare scenarios by changing one input at a time.
Limits of this compact model
This educational calculator cannot predict markets or account for every tax, fee, legal rule, benefit, insurance policy or personal circumstance. Verify material decisions with current documents and qualified advice.
