How the Savings Goal Calculator Works
The calculator uses the future value with contributions formula, compounded monthly:
Mode A (time) iterates month by month until balance ≥ target. Mode B (monthly) solves algebraically for PMT.
Worked Example
Goal: $50,000. Current savings: $5,000. Monthly contribution: $500. APY: 4.5%:
- Monthly rate = 4.5%/12 = 0.375%
- Reaches goal in approximately 6 years 8 months
- Total contributions: ≈ $45,000, interest earned: ≈ $5,000
- Already 10% of the way there with current $5,000 savings!
Frequently Asked Questions
How do I calculate how long it will take to reach a savings goal?▾
You need your target amount, current savings, monthly contribution, and expected APY. The formula uses compound interest with contributions: iteratively solve for t in FV = P(1+r)^t + PMT×[((1+r)^t-1)/r] until FV ≥ target.
How much do I need to save per month to reach $100,000?▾
At 5% APY for 10 years starting from $0: ≈ $644/month. At 4.5% APY for 5 years: ≈ $1,509/month. The more time you have, the less you need to save monthly thanks to compound interest.
What APY should I use for savings goal planning?▾
For emergency funds in a HYSA, use 4–5% APY. For conservative long-term investments, use 5–7%. For stock market index funds, historical averages suggest 7–10%. Always use a conservative estimate for planning.
Should current savings count toward my goal?▾
Yes. If you already have savings, they compound toward your goal too. A $10,000 head start at 5% APY grows to $16,289 in 10 years — so you only need to save toward the remaining balance.
What is a realistic savings goal timeline?▾
For a 3–6 month emergency fund ($15,000–$30,000): 1–2 years saving aggressively. For a house down payment ($50,000–$80,000): 3–7 years. For $1 million at retirement: 20–30 years with consistent monthly contributions and market returns.
