Savings Goal Calculator
Calculate the monthly amount you need to save to hit a financial goal by a target date.
What is a savings goal calculator?
A savings goal calculator tells you how much to put away each month to reach a target amount by a target date, allowing for what you already have and the interest it will earn along the way. Enter the goal, your current balance, the number of years and the account's APY above, and it returns the monthly deposit needed, the total you will deposit, and how much of the goal interest will cover.
It works for any goal with a number and a date attached: an emergency fund, a house down payment, a car bought in cash, a wedding, a sabbatical, next year's tuition, or a big trip. Turning "I should save more" into "$653 on the first of every month" is most of the battle.
How time changes the monthly number
Saving $50,000 with $5,000 already in the bank, at 4.5% APY:
| Time frame | Monthly deposit needed | Total deposited | Interest contributes |
|---|---|---|---|
| 1 year | $3,656 | $43,872 | $1,128 |
| 2 years | $1,779 | $42,696 | $2,304 |
| 3 years | $1,153 | $41,508 | $3,492 |
| 5 years | $653 | $39,201 | $5,799 |
| 10 years | $281 | $33,720 | $11,280 |
Doubling the time frame more than halves the monthly deposit, because interest does more of the work. At 0% interest the five-year figure would be $750 a month; at 4.5% it is $653 — the account earns the other $97.
Monthly deposit for common goals (3 years, from zero, 4.5% APY)
| Goal | Amount | Monthly deposit |
|---|---|---|
| Starter emergency fund | $10,000 | $260 |
| Used car, paid in cash | $20,000 | $521 |
| Full emergency fund (6 months of $8,000 expenses) | $48,000 | $1,250 |
| Down payment (20% on $500,000) | $100,000 | $2,603 |
Where to keep money you will need within five years
Money with a date on it should not be in the stock market — a 20% drop the year before you need it is not recoverable in time. The right home is something that cannot lose value and pays a competitive rate:
- High-yield savings account — FDIC-insured, instant access, currently around 4% APY at online banks versus near 0% at many branch banks. The default for emergency funds.
- Money market fund — similar yields, held at a brokerage; not FDIC-insured but invested in government paper.
- Certificates of deposit — lock money for 6–60 months for a fixed rate, with a penalty for early withdrawal. Good for a goal with a known date; a "CD ladder" keeps some money maturing regularly.
- Treasury bills — 4- to 52-week government debt bought at TreasuryDirect or through a broker; interest is exempt from state income tax.
- I bonds — inflation-linked savings bonds; must be held one year, and cashing in before five years forfeits three months' interest.
For goals more than five to seven years away — a house in a decade, a child's college fund — a mix that includes stock index funds is reasonable, accepting more year-to-year swing for higher expected growth; see the compound interest calculator.
Emergency fund: how much?
Three to six months of essential expenses — rent or mortgage, food, utilities, insurance, minimum debt payments, transport — not of income. A household spending $5,000 a month on essentials needs $15,000–$30,000. Lean toward six months (or more) with a variable income, a single earner, dependants, or a specialised job that would take time to replace; three months is reasonable for a dual-income household with stable jobs. Build a $1,000–$2,000 starter fund first, then pay off high-interest debt, then finish the fund.
Saving for a house down payment
A 20% down payment avoids private mortgage insurance on a conventional loan, but 3%–10% is common for first-time buyers, and FHA loans need 3.5%. Budget for closing costs too — 2%–5% of the loan — and keep the emergency fund intact after closing. First-time buyers can withdraw up to $10,000 of earnings from an IRA penalty-free for a home purchase, and Roth IRA contributions can always be withdrawn tax- and penalty-free, but raiding retirement accounts for a house trades decades of compounding for a slightly bigger house. See the down payment calculator and the mortgage calculator.
Formula
The calculator solves the future-value-of-an-annuity formula for the monthly payment:
PMT = (FV − PV × (1 + r)t) × m ÷ ((1 + m)n − 1)
- FV = the goal
- PV = starting balance, which grows to PV × (1 + r)t on its own
- r = annual rate (APY) as a decimal; t = years
- m = equivalent monthly rate = (1 + r)1/12 − 1
- n = number of monthly deposits = t × 12
Deposits are assumed at the end of each month. If the starting balance alone will grow past the goal, the monthly deposit is zero. At 0% interest the formula reduces to (FV − PV) ÷ n.
Worked example
Goal $50,000, starting balance $5,000, 5 years, 4.5% APY:
- The $5,000 grows on its own to 5,000 × 1.0455 = $6,231
- Deposits must cover 50,000 − 6,231 = $43,769
- Monthly rate m = 1.0451/12 − 1 = 0.003675; n = 60
- PMT = 43,769 × 0.003675 ÷ (1.00367560 − 1) = $653.35 a month
- Total deposited over five years: $39,201; interest earned on deposits and balance: $5,799
The same goal in 3 years needs $1,153 a month; in 10 years, $281.
How to use this calculator
- Enter the amount you want to end up with.
- Enter what you already have saved toward it (0 if starting fresh).
- Enter the number of years until you need the money (use decimals for part-years — 2.5 for thirty months).
- Enter the account's APY. Use 4–4.5% for a high-yield savings account or CD; use 0 to see the no-interest figure.
- Read the monthly deposit needed, the total you will deposit, and the interest that makes up the rest.
Making the deposit happen
- Automate it. Schedule a transfer for the day after payday. Savings that depend on willpower at month-end rarely happen.
- Separate accounts per goal. Most online banks let you create named sub-accounts ("House", "Car", "Emergency") — seeing each balance grow is motivating and prevents borrowing from one goal for another.
- Bank windfalls. Tax refunds, bonuses and a third paycheck month (biweekly earners get two a year) can knock months off the timeline.
- Re-run the numbers when the rate changes. Savings rates move with the Federal Reserve; a one-point drop on a five-year goal adds about $20 a month.
- Allow for inflation on long goals. A $50,000 goal ten years out will buy less; aim 2–3% higher per year if the price of the thing rises with inflation.

Frequently asked questions
Where should I park an emergency fund?
In a high-yield savings account at an FDIC-insured online bank — instant access, no risk of loss, and around 4% APY versus almost nothing at many branch banks. A money market fund at a brokerage is a close second. Not in stocks, not in a CD you cannot break, and not in your checking account where it will get spent.
Should I use a Roth IRA for a house down payment?
You can — contributions (not earnings) can be withdrawn at any time tax- and penalty-free, and first-time buyers can take up to $10,000 of earnings penalty-free — but it is usually a poor trade. Money taken out of a Roth loses decades of tax-free compounding and cannot be put back beyond the annual limit. Use it only as a last resort, and save the down payment in a high-yield account or CDs instead.
How much should my emergency fund be?
Three to six months of essential expenses — housing, food, utilities, insurance, minimum debt payments and transport, not your full income. Lean toward six months or more if your income is variable, you are the sole earner, you have dependants, or your job would take time to replace. Start with $1,000–$2,000, clear any high-interest debt, then build the rest.
Should I pay off debt or save first?
Build a small starter emergency fund ($1,000–$2,000) so a surprise bill does not go on a card, then attack any debt charging more than about 8% — a credit card at 22% costs far more than a savings account earns. Once high-interest debt is gone, finish the emergency fund and move to other goals. Keep contributing enough to a 401(k) to get the employer match throughout.
What interest rate should I use?
The APY of the account the money will actually sit in: roughly 4–4.5% for a high-yield savings account, money market fund or CD as of 2026, and 0% if it will sit in a checking account. Do not use stock-market returns for a goal under five years away; the rate is not guaranteed and a downturn at the wrong moment can wipe out years of deposits.
How do I save when there is nothing left at the end of the month?
Move the saving to the start of the month — an automatic transfer on payday, even $50 — so the budget adjusts around it rather than the reverse. Then look for one fixed cost to cut (an unused subscription, a cheaper phone plan, refinancing a high-rate loan) and redirect the whole saving. Raising income through overtime or a side job is the other lever, and every dollar of it can go straight to the goal.
Is a CD better than a savings account for a goal?
A CD locks a rate for a fixed term, which protects you if rates fall, but charges a penalty (often three to six months of interest) if you withdraw early. It suits a goal with a firm date more than a year away. A high-yield savings account is better for an emergency fund or any goal whose timing might change. Rates on the two are usually similar.
