Savings Goal Calculator — How Much to Save Per Month [2026]

The classic rule is saving 20% of take-home income (the 50/30/20 rule). For specific goals: Emergency fund (3–6 months expenses) in 12–24 months: divide goal by 12–24. House down payment (20% of $400K = $80K) in 3 years: ~$2,000/month assuming 2% HYSA. Use this calculator with your specific goal, timeline, and savings rate for a precise monthly number.

Use the actual APY from your savings account. High-yield savings accounts (HYSA) currently offer 4–5% APY. Traditional bank savings accounts typically offer 0.01–0.5% APY. Money market accounts: 4–5%. CDs (12-month): 4–5%. If you're investing rather than saving (stocks/ETFs), historically the S&P 500 returns ~7% annually after inflation. Enter the rate that matches where you'll keep your savings.

A savings goal is a specific financial target you want to reach by a certain date. Common savings goals include: emergency fund (3–6 months of expenses, typically $15,000–$30,000), home down payment (10–20% of purchase price), car purchase ($10,000–$30,000), vacation ($2,000–$10,000), college fund, and retirement milestones. Having a concrete goal and monthly savings target dramatically increases the likelihood of achieving it.

Compound interest means you earn interest on your interest, not just your principal. At 4% APY saving $500/month, after 3 years you'd have $19,355 from contributions plus $1,178 in interest. After 10 years: $73,624 total with $13,624 in interest (18.5% of your balance). The longer you save and the higher the rate, the more compound interest amplifies your results. Start early — time is your biggest advantage.

At $500/month with 4% APY: about 19 months. At $300/month: 32 months. At $1,000/month: about 9.5 months. The timeline varies significantly based on how much you save monthly and your interest rate. Use this calculator to find the exact timeline for any combination of monthly savings and interest rate.

Compare interest rates: if debt APR > savings APY, pay off debt first (guaranteed return = debt rate). Credit card debt at 20% APR costs far more than a 4% HYSA earns. The exception is a 3–6 month emergency fund — build this even while paying debt, as it prevents you from going further into debt when emergencies occur. For low-interest debt (mortgage at 3%, student loans at 4%), saving/investing alongside debt payoff often makes sense.
