Savings goals are calculated by considering your current savings, monthly contributions, interest rate, and target amount. The calculator shows how long it will take to reach your goal or how much you need to save monthly.
- Formula: Balance(m) = Balance(m−1) × (1 + r/12) + PMT, repeated monthly
- $500/month at 4% APY grows to $50,000 in about 6 years 5 months
- Compound interest adds ≈15% to total savings over a 5-year period at 4%
- Starting with $5,000 vs $0 saves roughly 10 months on a $50K goal
- Doubling monthly contributions cuts time-to-goal by more than half due to compounding
