How Investment Growth Is Estimated
Investment wealth accumulation combines two primary mechanisms: the initial capital invested and recurring contributions compounding over time under an assumed rate of return.
1. Mathematical Compounding Model
For an initial lump-sum investment, projected value after t years is evaluated using standard compounding:
- A = Projected Portfolio Value
- P = Initial Principal Investment
- r = Assumed Annual Return (as decimal)
- n = Compounding Periods Per Year (Annual=1, Semi-Annual=2, Quarterly=4, Monthly=12, Daily=365)
- t = Investment Duration in Years
2. Monthly Contribution Timing & Growth Mechanics
FinoQuick assumes monthly contributions are made at the end of each month (ordinary annuity convention). Each monthly period first applies the modeled growth to the starting balance, then adds the monthly contribution:
3. Total Principal vs. Estimated Growth
The projected future portfolio value is the sum of total principal invested (initial investment plus all monthly contributions) and estimated investment growth. When assumed returns are negative, estimated growth reflects a modeled reduction in portfolio value.
4. Impact of Rate Assumptions
Small changes in assumed annual return compound significantly over extended horizons. An increase of just 1% to 2% in annual return can produce substantial differences in terminal portfolio values over 20 to 30 years.
Important Investment Disclosures
This calculator provides mathematical projections based on the assumptions you enter. Actual investment returns can vary, including losses. Projected values are not guaranteed and this calculator does not provide investment advice.
- Assumed returns are hypothetical baselines and do not reflect specific financial securities or market predictions.
- Daily compounding follows the standard 365-day annual banking convention.
- Projections do not account for trading commissions, fund expense ratios, advisory fees, income taxes, or inflation.
