Savings Goal CalculatorHow Much to Save Each Month

Calculating a savings goal works backwards from a future target. Given a target amount, time horizon, and expected return, you can solve for the monthly contribution needed:

FV = P × (1 + r)^n + PMT × ((1 + r)^n − 1) / r

• FV — future value (your target)
• P — present savings
• PMT — monthly contribution (what we solve for)
• r — monthly return rate
• n — total number of months

Example: To reach $1,000,000 in 25 years starting from $10,000 at a 7% annual return, you'd need to save about $1,070/month. Of that final balance, more than half comes from investment growth — not contributions.

There's no single right number — it depends on income, goals, and time. Common benchmarks:

• 50/30/20 rule: 50% needs, 30% wants, 20% savings.
• Retirement: aim for 15% of gross income, including any employer match.
• Emergency fund: 3–6 months of expenses in cash.
• Big purchases: work backwards from cost ÷ months to deadline.

Use the calculator above to translate any target into a precise monthly number.

Compound interest means your returns earn returns. Over decades, this snowball effect often contributes more to your final balance than your actual contributions.

Example: Save $500/month for 30 years at 7%. You contribute $180,000 but end with about $610,000 — over $430,000 of pure growth. The dashed line on the chart above shows what you'd have without growth — the gap is compounding.

Five practical levers, in rough order of impact:

• Start earlier. Time is the single biggest factor. Five extra years can cut your monthly amount in half.
• Increase the rate. Moving from cash to a diversified portfolio can dramatically lift returns over decades.
• Automate contributions. Pay yourself first — set up automatic transfers on payday.
• Cut high-interest debt. Paying off a credit card at 20% beats earning 7% in stocks.
• Increase income. Even a small raise, fully saved, accelerates everything.

This savings calculator works backwards from a financial target. You tell it the amount you want to save, your time horizon, your current savings, and an expected annual return. It then solves the future-value-of-an-annuity formula for the missing piece — the monthly contribution you need to hit that goal.

It also projects year-by-year growth, separates contributions from interest earned, and optionally adjusts your target for inflation so you can see your goal in today's dollars. Use it for any savings goal: a house deposit, an emergency fund, a wedding, a new car, college tuition, early retirement, or financial independence.

If the monthly number above looks too high, you don't always have to earn more — small shifts in habits often free up hundreds per month. Here are practical ways to save more money each month:

• Automate the day you get paid. Move savings out before you can spend it. "Pay yourself first" is the single most reliable savings habit.
• Use a high-yield savings account (HYSA). Moving from a 0.1% account to a 4–5% HYSA can double your interest with zero risk.
• Cancel unused subscriptions. The average household leaks $20–$50/month on services they don't use.
• Cap discretionary categories. Set a hard monthly cap on dining, takeout, and online shopping — the three biggest budget leaks.
• Save raises and refunds. Treat every pay raise, tax refund, and bonus as savings by default, not as new spending money.

The same calculator works for every common savings goal — just change the target and time frame:

• Emergency fund: target 3–6 months of expenses, 6–18 month timeline, kept in cash or a HYSA (~4%).
• House deposit: target 10–20% of expected home price, 2–5 year timeline, conservative return (~3–5%).
• Retirement: target ~25× annual expenses (the 4% rule), 20–40 year timeline, diversified return (~6–7%).
• Big purchase (car, wedding, travel): work backwards from cost ÷ months to deadline at a conservative rate.

Try a few different targets and time horizons above to compare what each goal would cost you per month.

1. Enter your target amount — the total you want to save.
2. Add your current savings — anything you've already put aside counts.
3. Choose a time horizon — how many years you have to reach the goal.
4. Estimate your annual return rate — 4–5% for cash/HYSA, 6–7% for a diversified portfolio.
5. Optional: add an inflation rate — to see your goal in today's dollars.
6. Review the result — your required monthly contribution and a year-by-year growth chart.

• Saving for a house deposit — work out how much per month for a 20% down payment in 3–5 years.
• Building an emergency fund — calculate the monthly amount to hit 3–6 months of expenses.
• Saving for a wedding or honeymoon — break a $20K–$40K target into a clear monthly plan.
• College or tuition fund — project growth over 10–18 years for kids' education.
• Early retirement / FIRE — back out monthly savings needed to hit 25× expenses by age 50.
• Big purchase — new car, home renovation, or once-in-a-lifetime trip.

• Automate the transfer. Set savings to leave your account the day you get paid.
• Use a high-yield savings account. Moving from 0.1% to 4–5% APY can add thousands over a few years.
• Save every raise. Bank pay increases instead of inflating your lifestyle.
• Cut one big recurring cost. Renegotiating insurance, internet, or phone often saves $50–$100/month forever.
• Use windfalls strategically. Tax refunds, bonuses, and gifts can knock months off your timeline.
• Review every 6 months. Re-run the calculator to see if you're on track and adjust the monthly amount if needed.
