How Long to Save Calculator
Calculate how long it will take to save for a goal based on your monthly savings amount.
Saving for a goal is easier when you know exactly how long it will take. This calculator shows you the timeline and helps you adjust your monthly amount to hit your target faster.
The basic formula: Months = (Goal - Current Savings) / Monthly Savings
With interest (savings account or investments): For compound interest, the formula is more complex because your existing savings earn returns: Months = log((Goal × r/12 + Monthly) / (Current × r/12 + Monthly)) / log(1 + r/12)
Where r = annual interest rate.
Common savings goals and typical timelines:
- Emergency fund (3–6 months expenses): 6–18 months at 10–20% of income
- Vacation ($2,000–5,000): 3–12 months
- Down payment ($20,000–60,000): 2–5 years
- Car purchase ($15,000–35,000): 1–3 years
- Wedding ($20,000–40,000): 1–3 years
Where to keep your savings:
- High-yield savings account (4–5% APY in 2024) — Best for goals under 2 years
- CD ladder (4–5%) — Good for fixed timelines
- Index funds (7–10% historical average) — Best for goals 5+ years away, but volatile
- Regular savings (0.01–0.5%) — Worst option, barely beats inflation
The 50/30/20 rule: Allocate 50% of income to needs, 30% to wants, and 20% to savings. If you earn $4,000/month after tax, that means $800/month for savings goals.
Tip: Automate your savings. Set up an automatic transfer on payday so the money moves before you can spend it. Studies show automated savers are 2–3 times more likely to reach their goals.
