Reading growth and return scenarios
Separate a rate from its compounding convention
An annual effective return already describes a full year of growth. A nominal annual rate needs its compounding frequency to determine the effective growth. A quoted APY, a nominal interest rate and an arithmetic average return are therefore not interchangeable inputs. Use the convention named in the form.
Contributions change both the final balance and how much money you have put in. Compare growth with total contributions rather than calling the entire final balance profit. Timing matters: a beginning-of-period deposit earns growth for an extra period compared with an otherwise equal ending deposit.
Interpret projections as conditional arithmetic
A constant-return projection answers what would happen if the entered assumptions held. It does not model market volatility or establish a future return. Tax, product fees, withdrawals and inflation may change the result unless they are explicitly included.
When a term chart is shown, each point recalculates the same model for a different term. Change one assumption at a time and compare results using a consistent currency, return convention and time horizon.
Formula and calculation method
Each attendance-year cost=today’s annual cost×(1+inflation)^(years until enrollment+attendance year).
Target is the sum of projected attendance costs held at enrollment, conservatively assuming no investment return during college. Monthly deposits occur at month-end before enrollment; aid and tax benefits are excluded.
