Method and system for developing a time horizon based investment strategy
First Claim
1. A computer-implemented method for developing a time horizon based financial model for investing towards attaining at least one financial objective, each financial objective characterized by an event having a financial amount and a future time when the financial amount is expected to be needed, the method comprising the steps of:
- specifying a time horizon in accordance with the financial objectives, the time horizon divided into a plurality of segments;
providing an array of future expenses for each of the financial objectives, the array indicating recurring costs of a specified amount, frequency of the costs, and duration of the costs;
identifying a fraction of the future expenses accruing in each of the time horizon segments at each point in time, starting at the present time and going into the future;
modeling an investment of a specified amount of money during each of the time horizon segments for satisfying the future expenses, the amount of money invested changing as the time horizon changes from segment to segment;
determining an expected rate of return at each time horizon segment for the invested money, the expected rate of return changing as the time horizon changes from segment to segment, wherein the expected rate of return is a weighted average defined by;
##EQU19## wherein j ranges over the set of time horizon segments, from 1 to H, rj is the expected rate of return for the jth time horizon, xj is the amount of future expense in the jth time horizon going forward from the ith period, k ranges over the remaining periods, i to N, and yk is the expected expense in the kth period;
using the expected rates of return for determining amounts of money to be saved for fulfilling each of the financial objectives, the amount of money saved changing as the time horizon changes from segment to segment; and
saving the determined amounts of money for fulfilling each of the financial objectives.

Abstract
The present invention discloses a method and system for developing a time horizon based financial model for investing towards attaining at least one financial objective. Each financial objective is characterized by an event having a financial amount and a future time when the financial amount is expected to be needed. In the present invention, a time horizon is specified in accordance with the financial objectives. In addition, the time horizon is divided into a plurality of segments. An array of future expenses for each of the financial objectives is then provided. The array indicates recurring costs of a specified amount, frequency of the costs, and duration of the costs. A fraction of the future expenses accruing in each time horizon segment is then identified. An investment of a specified amount of money is then modeled during each of the time horizon segments for satisfying the future expenses. The amount of money invested may change as the time horizon changes from segment to segment. Next, an expected rate of return at each time horizon segment is then determined for the invested money. The expected rates of return change as the time horizon changes from segment to segment. The expected rates of return are then used to determine amounts of money to be saved for fulfilling each of the financial objectives. The amount of money saved may change as the time horizon changes from segment to segment.
