| |
|
| |
|
| Consider a set of cashflows which has:
| |
|
| |
|
| Net present value (NPV) of +$4m at a yield of 5%.
| |
|
| |
|
| NPV of -$4m at a yield of 6%.

| Using linear interpolation, the estimated yield at which the cashflows have an NPV of $0 is given by:
| | [[Category:The_business_context]] |
| | | [[Category:Identify_and_assess_risks]] |
| 5% + ( +4 / ( +4 - -4) ) x (6 - 5)%
| | [[Category:Manage_risks]] |
| | | [[Category:Risk_frameworks]] |
| 5% + ( +4 / +8 ) x 1%
| | [[Category:Risk_reporting]] |
| | | [[Category:Cash_management]] |
| 5% + 0.5%
| | [[Category:Financial_products_and_markets]] |
| | | [[Category:Liquidity_management]] |
| = '''5.5%'''.
| | [[Category:Technology]] |
| | |
| 5.5% is the estimated internal rate of return (IRR) of the cashflows.
| |
| | |
| | |
| ==Interpolation and Iteration==
| |
| Interpolation is often used in conjunction with Iteration.
| |
| | |
| Using iteration the straight-line estimated IRR of 5.5% would then be used, in turn, to recalculate the NPV at the estimated IRR of 5.5%, producing a recalculated NPV even closer to $0.
| |
| | |
| 5.5% and the recalculated NPV would then be used with interpolation once again to further refine the estimate of the IRR.
| |
| | |
| This iteration process can be repeated as often as required until the result converges on a sufficiently stable final figure.
| |
| | |
| | |
| ==Extrapolation==
| |
| | |
| Another closely related linear estimation technique is extrapolation.
| |
| | |
| This involves the straight-line estimation of values outside the range of the sample data used to do the estimation with.
| |
|
| |
| | |
| <span style="color:#4B0082">'''Example 2: Extrapolation'''</span>
| |
| | |
| Using the following data to estimate net present value (NPV) at a yield of 7%, using extrapolation:
| |
|
| |
| | |
| NPV of +$4m at a yield of 5%.
| |
| | |
| NPV of -$4m at a yield of 6%.
| |
| | |
| | |
| | |
| '''''Solution'''''
| |
| | |
| Based on the sample data, for every 1% increase in the yield, the NPV moved by:
| |
| | |
| -$4m - $4m = -$8m
| |
| | |
| | |
| Extrapolating this trend to a yield of 7%, this is a further increase in the yield of 7 - 6 = 1%.
| |
| | |
| The NPV would be modelled to fall from -$4m to:
| |
| | |
| = -$4m - $8m
| |
| | |
| = -$'''12m'''.
