How to Calculate Monthly Savings
The formula for calculating monthly savings with compound interest is: PMT = (FV \u2013 PV \u00D7 (1+r)^n) / (((1+r)^n \u2013 1) / r), where FV is your goal, PV is current savings, r is the monthly interest rate, and n is the number of months.
This calculator handles the math instantly. Just enter your goal amount, timeline, current savings, and expected interest rate. It shows you the exact monthly (or weekly/bi-weekly) amount needed, plus a visual breakdown of contributions vs interest earned.
Savings Account Interest Rates in 2026
High-yield savings accounts currently offer 4\u20135% APY from online banks like Marcus, Ally, and Discover. This is significantly higher than the 0.01\u20130.5% offered by traditional brick-and-mortar banks.
At 4.5% APY, a $50,000 balance earns about $2,250 per year in interest \u2014 compared to just $5 at a traditional bank. Over a 3-year savings plan, that interest can reduce how much you need to save each month by 5\u201310%.
Frequently Asked Questions
How do I calculate monthly savings?
Enter your savings goal, timeline, current savings, and expected interest rate. The calculator uses the future value annuity formula to determine the exact periodic payment needed. It accounts for compound interest on both your initial balance and ongoing contributions.
What savings account interest rates are available in 2026?
High-yield savings accounts from online banks currently offer 4–5% APY. Traditional bank savings accounts offer 0.01–0.5%. CDs may offer slightly higher rates (4.5–5.5%) for fixed terms. Money market accounts fall between these ranges.
Should I save or pay off debt first?
Pay off high-interest debt (credit cards at 15–25%) before saving beyond a small emergency fund. If your savings earn 4.5% but your debt costs 20%, paying debt gives a better return. Exception: always save enough for a small emergency fund ($1,000) to avoid new debt.
How does contribution frequency affect savings?
More frequent contributions compound slightly faster. Bi-weekly contributions mean 26 payments per year instead of 12, adding an extra month of savings. The difference is small but measurable over long timelines.
What is the difference between APR and APY?
APR is the simple interest rate without compounding. APY includes the effect of compounding. A 4.5% APR compounded monthly gives about 4.59% APY. Banks typically advertise APY for savings accounts (higher number looks better) and APR for loans (lower number looks better).
How much should I have saved by age 30?
Common benchmarks: 1× your annual salary by 30, 3× by 40, 6× by 50, and 8× by 60. These are guidelines for retirement savings and don’t include separate emergency fund or short-term goal savings. Median savings for Americans under 35 is about $20,000.
