Savings Goal Calculator: How Much to Save Monthly
Every savings goal — a house down payment, an emergency fund, a wedding, a car — is just three numbers: how much, by when, and what you already have. This free calculator turns them into one actionable answer: the exact amount to transfer to savings every month.
Savings Goal Calculator
How to Use This Calculator
Enter your target amount, what you've already saved, and how many years you have. Add the interest rate your savings will earn — for a bank account, use its APY.
Click Calculate to see the monthly amount you need to save, the total you'll contribute, and how much interest chips in. If the number feels too high, stretch the deadline by a year or two and recalculate — a small extension makes a big difference.
The Formula
The required monthly payment is PMT = [FV − P(1 + i)ⁿ] × i ÷ [(1 + i)ⁿ − 1], where FV is the target, P your current savings, i the monthly interest rate and n the number of months. It's the compound interest formula rearranged to solve for the contribution instead of the balance.
Worked example: target $50,000 in 5 years, $8,000 already saved, earning 4% APY. Monthly rate i = 0.04 ÷ 12 = 0.003333, n = 60. The $8,000 grows to 8,000 × 1.003333⁶⁰ = $9,768 on its own. The remaining $40,232 must come from contributions: PMT = 40,232 × 0.003333 ÷ (1.003333⁶⁰ − 1) = $606.83 per month. Without interest, the same goal would need $700 per month — compounding saves you about $93 a month.
Tips
Open a dedicated account for each major goal. Separate accounts make progress visible and make it psychologically harder to raid one goal to fund another.
Automate the transfer for the day after payday. Goals funded by automatic transfers succeed far more often than goals funded by willpower.
Raise the amount whenever your income rises. If you get a 3% raise, raise your savings transfer by at least half of it — you'll barely notice the difference in spending and cut months off your goal.
Frequently Asked Questions
How much should I have in an emergency fund?
The standard guideline is 3 to 6 months of essential living expenses. If your job is stable and you have few dependents, 3 months is reasonable; if your income is irregular or you support a family, aim for 6 months or more. Keep it in a high-yield savings account where it's safe, liquid and earning interest.
Where should I keep money I'm saving for a goal?
Match the account to the timeline. Goals under 3 years away belong in safe, liquid accounts — high-yield savings or money market accounts. Goals 3 to 10 years out can take modest risk, like a balanced portfolio. Goals more than 10 years away can handle stock-heavy investing. The closer the deadline, the less risk you want.
How do I find extra money to save each month?
Automate first: schedule a transfer to savings on payday before you can spend it. Then look for big fixed costs — renegotiating insurance, cutting a subscription or two, or cooking more meals at home often frees up $100 to $300 a month with almost no lifestyle pain. Small recurring wins compound into real money.
What if I can't save the monthly amount the calculator shows?
You have three levers: save less per month and extend the deadline, trim the goal amount, or earn more (side income, selling unused items). Most people find extending the deadline the easiest. The calculator shows the trade-off exactly — try adding 6 or 12 months to the timeline and watch the required monthly amount drop.
Should I invest money meant for a savings goal?
Only for goals far enough away to ride out market swings. A goal you need in 2 years has no time to recover from a market dip, so keep it in cash or equivalents. A goal 15 years away — like a child's college fund — can usually handle stock-heavy investing, which is also the only way to meaningfully beat inflation.
