Savings Goal Calculator
Have a number in mind and a deadline? This calculator works backwards to tell you exactly how much to save each month to get there — with any interest you'll earn already factored in. Adjust your goal, starting balance, rate and timeframe to build a plan you can actually stick to.

How to back into a monthly savings number
Most savings advice runs forward: put away what you can and see where you land. A savings goal calculator flips that around. You start with the finish line — a specific dollar amount and a specific deadline — and solve for the one number that actually drives your behaviour: how much to set aside each month. That single figure is far easier to commit to than a vague intention to "save more."
The math has two moving parts. First, whatever you've already saved keeps growing on its own between now and your deadline, so it covers part of the goal without any new deposits. Second, each monthly contribution you add also earns interest for the rest of the timeframe. The calculator grows your current balance forward, subtracts it from the goal, and then works out the steady monthly deposit whose compounded value fills the remaining gap exactly.
Because the contributions are spread evenly and compound at the same rate, the result is a single, repeatable number. Pay that amount into your savings account every month and — assuming the rate holds — you land right on your target. The year-by-year table above shows the balance climbing toward the goal so you can see the plan working, and watch how little of the final total typically comes from interest on a short timeline.
The most reliable way to hit the number is to pay yourself first: set up an automatic transfer for the day after payday so the money moves before you can spend it. Automating the deposit turns a goal that depends on willpower into one that runs on autopilot, and it's the single biggest predictor of whether people actually reach their targets.
The formula & how we calculate it
This is the future value of an annuity formula, rearranged to solve for the monthly payment. In plain English: take your goal, subtract what your current balance will grow into on its own, and divide what's left by a factor that accounts for each deposit earning interest until the deadline.
FV = your savings goal (the future value you want)
PV = your current balance (present value)
i = monthly interest rate = annual rate ÷ 12 ÷ 100
N = number of months = years × 12
Worked example (the defaults above):
- Goal
FV= $25,000, current balancePV= $2,000. - 4% annual rate ÷ 12 = a monthly rate
iof 0.3333% (0.0033333). - Timeframe
N= 5 × 12 = 60 months. - Your $2,000 grows to about $2,000 × (1.0033333)60 ≈ $2,442 on its own.
- Solve: PMT = (25000 − 2442) × 0.0033333 ÷ ((1.0033333)60 − 1) ≈ $340.25 / month.
- Over 60 months you contribute about $20,415 and earn roughly $2,585 in interest, landing at $25,000.
If the interest rate is 0% (or you leave it blank), the formula simplifies to the gap divided by the number of months: (FV − PV) ÷ N. And if your current balance is already on track to grow past the goal on its own, the required monthly contribution is simply $0 — you're done.
What changes how much you need to save
- Your timeframe. This is the biggest lever. Stretching the deadline spreads the goal across more months, so each contribution shrinks. Pulling it in raises the monthly amount sharply. If the number feels impossible, the most effective fix is usually more time.
- What you've already saved. Money in the account today both shrinks the gap and grows on its own until the deadline, so a healthy starting balance can meaningfully cut your monthly contribution.
- The interest rate. A higher APY trims the required deposit, but on short horizons the effect is modest — your own contributions still do most of the work. Don't count on interest to rescue an aggressive timeline.
- The goal itself. Obvious but worth stating: a bigger target needs bigger monthly deposits. If the plan won't fit your budget, it's fair to scale the goal down rather than overcommit and quit.
- Consistency. The formula assumes you contribute every single month. Skipped months mean the remaining deposits have to grow to catch up — automating the transfer is what keeps the plan honest.
Glossary
- Savings goal
- The specific dollar amount you're aiming to have saved by a chosen deadline — the future value the calculator solves for.
- Principal / current balance
- The money you've already set aside toward the goal. It both reduces the gap and keeps earning interest until your deadline.
- Monthly contribution
- The steady amount you deposit each month. This is the figure the calculator returns — the one number you have to act on.
- APY (Annual Percentage Yield)
- The yearly return on your savings, including the effect of compounding. We divide it by 12 to get the monthly rate used in the formula.
- Time horizon
- How long until you need the money. Longer horizons lower the monthly contribution and give interest more time to help.
- High-yield savings account (HYSA)
- An FDIC-insured savings account that pays a much higher rate than a typical bank account, while keeping your money safe and liquid.
- Future value
- What a sum of money will be worth at a later date once interest has been applied. The whole calculation is built around reaching a target future value.
Frequently asked questions
How much do I need to save per month to reach $25,000 in 5 years?
Starting from $2,000 already saved and earning 4% interest, you'd need to set aside about $340 per month for 60 months. Over that time you'd contribute roughly $20,415 of your own money and earn about $2,585 in interest, landing right at $25,000. With no interest at all you'd need around $383 per month. Adjust the goal, starting balance, rate and timeframe above to match your own plan.
Where should I keep money I'm saving for a goal?
For goals you'll reach within about five years, a high-yield savings account, money market account or short-term CD is usually the right home. Your principal is protected (FDIC- or NCUA-insured up to the limits), the money stays liquid, and you still earn a meaningful return. Avoid putting money you'll need soon into the stock market, where a downturn could leave you short right when you need the cash.
Does interest really matter for short-term goals?
It helps, but on short horizons your contributions do almost all the heavy lifting. In the default example, $20,415 of the $25,000 goal comes from money you deposit and only about $2,585 from interest. Over a few years there simply isn't enough time for compounding to dominate. A higher rate trims your required monthly contribution a little, but the size and consistency of your deposits matter far more.
Should I save or invest for a goal 5 years away?
For a hard deadline around five years out, most people lean toward saving in a high-yield account or CD rather than investing, because there isn't much time to recover from a market drop. The closer and more non-negotiable the goal, the more you favour safety and liquidity. For goals a decade or more away, investing for growth becomes more reasonable because you have time to ride out volatility.
How is the required monthly savings calculated?
We use the future-value-of-an-annuity formula solved for the payment. First we grow your current balance forward to the deadline. Then we work out the monthly deposit whose compounded future value covers the remaining gap: PMT = (FV − PV·(1+i)N) · i / ((1+i)N − 1), where FV is your goal, PV is your current balance, i is the monthly rate (annual ÷ 12) and N is the number of months. If the rate is 0%, it simplifies to the gap divided by the number of months.
What's a high-yield savings account?
A high-yield savings account (HYSA) is a regular, FDIC-insured savings account that pays a much higher interest rate than a typical big-bank account — often many times the national average. They're usually offered by online banks and credit unions with low overhead. The money stays liquid and safe, which makes a HYSA a popular home for goal savings and emergency funds.
How big should my emergency fund be?
A common rule of thumb is three to six months of essential expenses, kept in an easily accessible high-yield savings account. If your income is variable or your job is less secure, aim toward the higher end. Build the emergency fund before — or alongside — other goals, since it's what keeps a surprise expense from derailing the rest of your plan. You can use this calculator to find the monthly amount needed to build that cushion by a target date.
