Testing and Final Adjustments
Test the calculator using known bond examples with varying coupon rates, market rates, and maturities. Verify that Zero-coupon and coupon-bearing bonds produce correct results. Validate formulas:
- Bond Price (coupon bond): \( P = \sum \frac{[\frac{C}{(1+r)^{t}}]+F}{\frac{F}{(1+r)^{n}}} \)
- Zero-coupon bond: \( P = \frac{F}{(1+r)^{n}} \)
Compare to manual and financial software. Check inputs to ensure that they are not empty, negative, or non-numeric. Round off the outputs to the nearest two decimals. Desktop, tablet, and mobile responsiveness. Confirm dynamic updates upon changing of inputs. Maximize the layout to show the price, yield, as well as the maturity value. All calculations should be done locally, and no user data should be saved.
