How long to save $20,000 with $500/month at 4%?

Using FV annuity: approximately 37 months (just over 3 years). The interest earned shaves roughly 3 months off a no-interest timeline.

Does starting balance matter?

Significantly. An existing $5,000 balance earning 4% grows to $7,333 in 5 years, reducing the required monthly contributions to hit any target.

What if I increase contributions over time?

Even a 3% annual increase in monthly savings dramatically shortens the timeline due to compounding on larger balances.
