Free savings account comparison calculator. Compare up to 4 accounts side by side by APY, minimum balance, fees, and compounding frequency to find the best net earnings over 1, 5, and 10 years.
The Savings Account Comparison Calculator lets you compare up to four savings accounts side by side. Enter each account's APY, compounding frequency, minimum balance, and monthly fees to see net earnings projected over 1, 5, and 10 years.
Not all savings accounts are created equal. A small difference in APY or a seemingly minor monthly fee can compound into hundreds or thousands of dollars over the years. This calculator reveals those differences by computing true net returns after fees for each account.
Whether you are choosing between major banks, online banks, credit unions, or money market accounts, this tool gives you the data to select the account that puts the most money in your pocket. Small differences in APY, minimum balance requirements, and monthly fees can compound into hundreds or even thousands of dollars over a savings horizon. Comparing the true net return across accounts ensures your money is working as hard as possible.
Advertised APY alone does not tell the whole story. Fees, compounding frequency, and minimum balance requirements all impact your actual returns. This calculator accounts for all of these factors so you can compare accounts on a truly apples-to-apples basis. This prevents you from choosing a high-APY account whose fees quietly eat into your actual returns.
Compound Growth: FV = P × (1 + APY/n)^(n×t) Annual Fees = Monthly Fee × 12 Net Earnings = (FV – P) – (Annual Fees × t) where P = principal, n = compounding periods/year, t = years
Result: 10-year difference: $10,734
Big Bank at 0.50% APY with $5/month fee: 10-year net earnings are $649 (interest) – $600 (fees) = $49. Online Bank at 4.50% APY with no fees: 10-year net earnings are $10,783. The difference is $10,734 over 10 years — all from choosing the right account.
The difference between a 0.50% APY and a 4.50% APY on $25,000 is dramatic: about $1,000 per year in interest. Over a decade, that gap grows to over $10,000 with compounding. Yet many consumers leave money in low-earning accounts at their primary bank simply out of inertia. A systematic comparison removes that inertia.
APY is the most important factor, but not the only one. Check minimum balance requirements (to avoid fees), monthly maintenance fees, transaction limits, mobile app quality, and how easy it is to move money in and out. An account with a slightly lower APY but no friction may be more practical.
If you have small savings balances at multiple banks, consolidating them into one high-yield account can be more efficient. You earn the top APY on a larger balance, simplify account management, and may qualify for relationship perks or fee waivers.
At current rates, the difference between daily and monthly compounding is small — a few dollars per year on a $25,000 balance. However, the gap grows with higher rates and larger balances. Daily compounding is slightly better but the APY already accounts for compounding frequency.
Both matter, but on smaller balances, fees have a larger impact. A $5/month fee costs $60/year regardless of balance, while a 0.5% APY increase on $5,000 yields only $25 more. On larger balances ($50,000+), APY differences dominate. This calculator helps you quantify the trade-off.
Savings rates are variable and typically move with the federal funds rate. Banks can change rates at any time, though they usually follow Fed rate changes within a few weeks. High-yield online banks tend to adjust faster than traditional banks.
Yes, as long as the bank is FDIC-insured (or NCUA-insured for credit unions). Your deposits are protected up to $250,000 per depositor, per ownership category, regardless of the APY. Online banks offering high APYs are held to the same insurance standards as traditional banks.
As of recent years, top high-yield savings accounts offer 4–5% APY. Traditional bank savings accounts typically offer 0.01–0.50% APY. Any account offering above 3% APY is generally competitive, though rates fluctuate with monetary policy.
Yes. There is no limit on how many savings accounts you can have. Some people spread deposits across banks for FDIC coverage or to take advantage of promotional rates. The main trade-off is the complexity of managing multiple accounts.
