Quick Answer
To calculate the monthly savings needed to reach a goal, use the PMT formula: Monthly Saving = (Goal − Current Savings × (1+r)ⁿ) × r ÷ ((1+r)ⁿ − 1), where r is the monthly interest rate and n is the number of months. For example, to save $50,000 in 5 years at 5% annual return with no existing savings, you need to save approximately $735 per month.
What Is Savings Goal?
A savings goal calculator tells you exactly how much you need to set aside each month to reach a specific financial target — whether that is a down payment for a house, your child's university fees, a car, Hajj expenses, or an emergency fund. It takes the guesswork out of saving by working the answer backwards from your goal.
Unlike a compound interest calculator (which tells you how your existing money grows), a savings goal calculator solves for the monthly deposit needed. It combines the future value of your current savings with the future value of a series of regular monthly deposits to reach your target.
The calculator accounts for the return on your savings (bank profit rate, savings account rate, or expected investment return), which means you need to save less per month than the simple division of goal ÷ months would suggest — your money is working for you too.
How to Use
- 1Enter your savings goal — the total amount you want to accumulate (e.g. $50,000).
- 2Enter how much you have already saved toward this goal. Enter 0 if you are starting fresh.
- 3Enter how many years you have to reach this goal.
- 4Enter the annual return you expect to earn on your savings. This could be a savings account or deposit rate, the expected return from an investment fund, or 0 if you are keeping cash at home. Use the rate your bank or fund actually offers, and stay conservative.
- 5Read the monthly savings amount — this is what you need to deposit every month from now until your deadline.
Formula
PMT = (Goal − PV × (1+r)ⁿ) × r ÷ ((1+r)ⁿ − 1)r = monthly rate (annual% ÷ 1200) · n = months · PV = current savings
FV of current savings = PV × (1 + r)ⁿThis is subtracted from the goal to find how much the monthly deposits need to cover
Monthly = (Goal − Current Savings) ÷ MonthsIf interest rate is 0%, this simpler formula applies
Example: Save $20,000 in 3 years at 5% annual return, starting with $2,000
- Goal = 20,000
- Current savings (PV) = 2,000
- Years = 3 → months (n) = 36
- Monthly rate (r) = 5% ÷ 12 ÷ 100 ≈ 0.004167
- PV grows to: 2,000 × (1.004167)^36 = 2,322.94
- Remaining gap: 20,000 − 2,322.94 = 17,677.06
- PMT = 17,677.06 × 0.004167 ÷ ((1.004167)^36 − 1) ≈ 456.14
You need to save approximately $456 per month for 3 years. Your $2,000 head-start saves you about $60 per month compared to starting from scratch.
Tips & Things to Know
- Even small interest rates make a significant difference over time. At 0% return, saving $50,000 in 5 years requires about $833/month. At a 5% annual return, only about $735/month, so you save roughly $98 per month just by earning a return.
- Automate your monthly saving the day your salary arrives. Studies consistently show that people who automate savings reach their goals more reliably than those who try to save 'whatever is left' at month end.
- Compare low-risk options for medium-term goals, such as high-yield savings accounts, certificates of deposit, government savings bonds or Islamic savings products. Rates differ by country and change over time, so check current offers and any guarantees or deposit protection before you decide.
- Account for inflation in long-term goals. If your goal is $50,000 today but you have 10 years to save, at 3% inflation the real cost may be about $67,000 by the time you need it. Adjust your goal upward for long timelines.
- If the monthly savings amount seems too high, try extending the timeline, lowering the goal amount, or finding a higher-return investment. Even one extra year can dramatically reduce the required monthly deposit.
