Savings Goal Calculator

How to use this calculator

This "how much do I need to save each month" calculator works backward from your goal. Tell it what you want and when, and it gives you a monthly, biweekly and weekly amount.

Start with these inputs:

• Goal. Type an amount, or pick a preset: emergency fund, down payment, car, vacation or wedding. Presets are starting points, so adjust them to your plans.
• Already saved. Money you've already set aside for this goal.
• APY. The annual percentage yield on your savings account. Top high-yield accounts pay around 4% right now. Check your bank's site for your rate.

Then choose a mode:

• Mode A: how much to save. Enter the number of months. You'll see the deposit needed each month, every two weeks, and each week.
• Mode B: how long it takes. Enter what you can save monthly. You'll see how many months it takes to reach the goal.

Both modes show the interest you'll earn and a balance chart. The per-paycheck breakdown makes it easy to set up an automatic transfer that matches your pay schedule.

How we calculate your monthly savings

The calculator grows what you've already saved, then finds the steady deposit that covers the rest.

First, convert your APY to a monthly rate. APY already includes compounding, so we use:

Monthly rate (i) = (1 + APY)^(1/12) − 1

Then find the deposit:

Growth of current savings = S × (1 + i)^n
Monthly deposit = (Goal − S × (1 + i)^n) × i / ((1 + i)^n − 1)

S = already saved, n = months

For biweekly and weekly amounts, the same math runs with 26 or 52 periods per year.

Worked example: $15,000 in 24 months

Say your goal is $15,000. You have $1,000 saved, 24 months to go, and a 4% APY.

• Monthly rate: (1.04)^(1/12) − 1 = 0.327%
• Your $1,000 grows to about $1,081.60.
• You still need about $13,918.40 from deposits.
• Monthly deposit: about $558
• Every two weeks: about $258
• Every week: about $129

You'd deposit about $13,402 in total. Interest covers the remaining $598 or so. Without interest, you'd need $583 a month, so the high-yield account saves you about $25 a month.

Interest helps, but your deposits do most of the work on short goals. That's normal. Over just two years, the habit matters more than the rate.

How long does it take to save $10,000?

Use mode B to answer this. Here's what it looks like starting from $0 at 4% APY:

Monthly savings	Time to reach $10,000	Interest earned
$300	32 months	~$500
$400	25 months	~$400
$500	20 months	~$317
$800	13 months	~$200

Saving more each month gets you there faster. You earn less interest in total, simply because the money sits for a shorter time.

Emergency fund calculator: how much is enough?

A common guideline is 3 to 6 months of essential expenses. Essentials are what you must pay even if your income stops: housing, utilities, food, insurance, transportation and minimum debt payments.

For example, if your essentials are $3,500 a month:

• 3 months: $10,500
• 6 months: $21,000

You may want to aim higher if your income is irregular, you're self-employed, or you support a family on one income. Two steady incomes may mean a smaller target works.

If that number feels huge, start smaller. A starter fund of $1,000 to $2,000 can cover many common surprises, like a car repair. Build from there.

Down payment savings and other big goals

A down payment is often the largest goal people save for. Many buyers put down less than 20%, though that usually means paying PMI. Our how much house can I afford calculator helps you set a target. Remember closing costs, typically 2%–5% of the loan.

For a car, a bigger down payment can lower your loan payment. Try different amounts in the auto loan calculator.

If your goal is 5 or more years away, savings may not keep up with inflation. Some people invest part of long-term savings instead, accepting more risk. Our compound interest calculator shows how different rates play out.

Where to keep your savings

For goals within a few years, safety and easy access usually matter more than high returns.

Account	Typical features
High-yield savings account	Variable rate, top accounts around 4% APY, easy transfers
Money market account	Similar rates, may include checks or a debit card
Certificate of deposit (CD)	Fixed rate for a set term; early withdrawal penalty

Top 1-year CDs pay around 4.25%–4.6% APY right now. They work well when you know exactly when you'll need the money. Compare terms with our CD calculator.

Check that your bank is FDIC-insured, or NCUA-insured for credit unions. Coverage is $250,000 per depositor, per insured bank, per ownership category.

Automate it, and use sinking funds

Automating transfers is one of the simplest ways to stay on track. Schedule a transfer for the day after payday, using the per-paycheck amount from the calculator. You won't have to remember, and the money leaves before you can spend it.

A sinking fund is savings for a known cost that isn't monthly. Think car insurance, holiday gifts, annual subscriptions or home repairs. Divide the cost by the months until it's due, and save that each month.

For example, a $1,200 insurance bill due in 10 months means saving $120 a month. When the bill arrives, the cash is waiting.

Many online banks let you open several savings "buckets" in one account. Give each goal its own bucket so you can see progress at a glance.

If you're carrying high-interest debt, you may want to balance saving with paying it down. Our credit card payoff calculator shows what that debt is costing you.
