The solid area is projected balance, the dashed line is the working goal, circles mark milestones, and the vertical marker identifies the target month.
Projected $25,431.33 by September 2028 against a $25,000.00 goal. Milestones reached by the target: 25% in October 2026; 50% in June 2027; 75% in February 2028; 100% in September 2028.
Current savings, new personal contributions, and interest are additions. Fees extend below zero and are explicitly treated as a subtraction.
Current savings $5,000.00 + personal contributions $19,065.68 + interest $1,365.65 − fees $0.00 = projected balance $25,431.33.
The model divides the nominal expected annual return by 12. With end-of-month timing, growth applies to the beginning balance before deposits. With beginning timing, regular and additional contributions receive that month’s modeled growth.
The submitted monthly amount applies in months 1–12. The annual increase begins in month 13 and compounds again in months 25, 37, and later. Values remain unrounded inside the simulation and are rounded only for display.
Named one-time deposits are combined when they share a month and remain itemized in the schedule. The monthly account fee is deducted once at month end and is capped at the available balance, so it cannot create a negative balance.
When enabled, the entered goal stays expressed in today’s dollars. The calculator grows a separate nominal working target using the inflation assumption and the calendar distance from start month to target month.
A bounded numerical search repeatedly runs the same full simulation to find a first-year monthly contribution that meets the target. Milestones and the estimated goal date use a separate projection of up to 600 months.
The monthly table exposes each balance transition, contribution, interest amount, fee, and goal-progress ratio. The yearly table aggregates those exact monthly records and labels partial calendar years with their true month ranges.
Expected returns and inflation are assumptions, not guarantees. Markets, account rules, deposit dates, rate changes, taxes, and fees can differ from the simplified monthly model and materially change an outcome.
The calculation uses fixed nominal return, inflation, fee, and contribution-growth assumptions. It excludes taxes, withdrawals, variable returns, daily compounding, weekly or biweekly deposits, and Monte Carlo analysis.
No. It treats the expected return as a nominal annual rate and divides it by 12 for monthly compounding. An actual account or investment may compound differently.
The required amount uses the same monthly simulation as the projection, including current savings, compound growth, contribution timing, annual increases, fees, additional contributions, and optional inflation adjustment.
Beginning-of-month regular and additional contributions receive that month’s modeled growth. End-of-month contributions are added after growth is calculated.
The initial monthly contribution applies for months 1 through 12. The percentage increase is applied without intermediate rounding in months 13, 25, 37, and every 12 months after that.
It keeps the entered goal in today’s dollars and increases the working nominal target using the expected annual inflation rate and the number of months to the target.
No. The return is only an assumption for planning. Actual returns, account fees, contribution timing, and inflation can differ materially from the model.
The calculator reports that the goal date is outside the projection horizon and does not invent a date. The target-date projection and its monthly schedule are still shown.
