How much to save each month
Whether you're building a down payment, a wedding fund, or a new-car reserve, the real question is: how much do I put aside every month to get there on time? Enter your goal, what you've already saved, your timeline, and an expected return, and this tool works backward to the monthly amount you need — and shows how much of the goal your returns cover. Everything runs in your browser — nothing is uploaded.
How the monthly amount is found
- The tool solves the future-value formula for the monthly deposit: PMT = (goal − current × (1 + i)N) ÷ (((1 + i)N − 1) ÷ i), where i is the monthly rate and N the number of months.
- Your current savings keep growing at the same return, so the more you start with, the less you need to add each month. If it already grows past the goal on its own, the required deposit is zero.
- Deposits are treated as made at the end of each month and the return is applied monthly (annual rate ÷ 12). Real returns vary; a savings account is steady, while investments swing year to year.
- Figures are in today's dollars and ignore taxes on interest or gains. For a long horizon, remember inflation raises the real cost of a fixed-dollar goal.
An estimate for planning, not financial advice. Investment returns are never guaranteed, and a shorter timeline means a market dip could leave you short — keep near-term goals in safer, steadier accounts. Revisit the plan as your situation changes.
How much should I save each month?
Most savings advice runs forward: put away X and see what it grows to. A goal works the other way. You know the finish line — a $50,000 down payment, a $20,000 wedding, a $15,000 car — and the date you need it. This calculator runs the math backward, dividing the gap between your goal and your growing balance across the months you have, so you get a single, concrete number to automate.
Why your expected return matters
The return you earn does part of the work for you. Over a short horizon at a modest savings-account rate, that help is small and most of the goal comes from your own deposits. Over a longer horizon at investment-like returns, compounding can cover a meaningful slice of the target — but with more ups and downs along the way. That's the trade-off behind where you keep the money.
Match the account to the timeline
- Under ~2 years: favor a high-yield savings account or CDs, where the balance can't drop right before you need it. Size a cash buffer with our emergency fund calculator.
- 3–5 years: a conservative mix; some growth, but not so much that a bad year derails the goal.
- 5+ years: you can lean toward investments and let compounding help — see the long-run effect in the compound growth calculator.
Turn the number into a habit
The savers who hit their goals almost always automate the transfer — money moves the day after payday, before it can be spent elsewhere. If the monthly figure feels too high, you have three levers: extend the timeline, lower the goal, or find room in your budget. Even a partial automatic transfer started today beats a perfect plan you never begin.
Frequently asked questions
How much do I need to save each month to reach $50,000 in 5 years?
Starting from $8,000 and earning about 4% a year, you'd need roughly $600 a month to reach $50,000 in five years — your existing savings and returns cover the rest. With no starting balance it climbs to about $750 a month. Enter your own numbers above for an exact figure.
What return should I assume?
Match it to where the money will sit. A high-yield savings account or CD might earn 4–5% today; a diversified investment portfolio has historically averaged more but with real risk of down years. For short goals, use a conservative rate — you don't want a market drop right before the deadline.
What if I already have some savings?
Enter it as your current balance. That money keeps growing at your expected return, which lowers the monthly amount you need to add. If your starting balance is large enough that it grows past the goal on its own, the calculator shows a required deposit of zero.
Does this account for inflation?
No — it works in today's dollars. If your goal is years away and its real cost will rise with inflation, pad the target a little. Our inflation impact calculator shows how much a future price grows over time.
What if the monthly amount is more than I can save?
You have three levers: give yourself more time, trim the goal, or free up room in your budget. Even saving less than the ideal amount, started now and automated, gets you most of the way — and you can raise the contribution as your income grows.
