Did You Know?
How Does a Savings Plan Work?
Compound Interest
Interest earns interest. FV = PV(1+r)^n + PMT × (((1+r)^n - 1)/r). Monthly compounding means r is divided by 12, n is months.
Annual Contribution Increases
Raising contributions each year (e.g., with raises) dramatically boosts final value. A 3% annual increase on $500/mo for 30 years yields ~40% more than flat $500/mo.
Real vs. Nominal Returns
At 3% inflation, 8% nominal = 5% real. Plan using real returns for purchasing power. Increase contributions to offset inflation.
