How much interest will I earn on my savings?

Your savings interest depends on your balance and the APY (Annual Percentage Yield). At 4.50% APY: $1,000 earns $45/year; $5,000 earns $225/year; $10,000 earns $450/year; $25,000 earns $1,125/year; $50,000 earns $2,250/year; $100,000 earns $4,500/year. At the national average of 0.41% APY, the same amounts earn roughly 91% less. The account type you choose is the biggest factor in savings earnings.

How is savings account interest calculated?

Savings account interest is calculated using APY (Annual Percentage Yield), which accounts for compounding. Simple formula for approximate annual interest: Balance x APY = Annual interest earnings. Example: $20,000 x 0.045 (4.50% APY) = $900/year. With daily compounding (which most savings accounts use), the actual return is slightly higher than the simple rate — the APY figure already accounts for this compounding effect, so using APY in the formula gives you an accurate annual estimate.

What is a good APY for a savings account in 2026?

A good APY for a savings account in 2026 is 4.35% or higher. The FDIC national average savings account rate is 0.41% APY — any rate significantly above this is good. Online high-yield savings accounts routinely pay 4.35–4.75% APY. Traditional big-bank savings accounts typically pay 0.01–0.10% APY. The difference is enormous: on $20,000, the gap between 0.41% and 4.50% is $818 per year.

Does savings account interest count as income?

Yes. Interest earned in a standard (taxable) savings account is ordinary income for federal tax purposes. Your bank will send a 1099-INT form if you earn $10 or more in interest during the year. You must report all savings interest on your federal tax return regardless of amount. Interest is taxed at your ordinary income rate (10–37% depending on bracket). State income tax also applies in most states (exceptions: Texas, Florida, Washington, Nevada, and a few others with no income tax).

How can I earn more interest on my savings?

Steps to earn more: 1) Move from a big-bank savings account (0.01%) to an online HYSA (4.50% APY) — the single highest-impact action; 2) For money you won't need for 6–18 months, use a CD at similar or slightly higher rates; 3) Keep your emergency fund at an online bank rather than a local branch savings account; 4) For very large balances ($100K+), consider Treasury bills (state-tax exempt). The difference between the national average and best rates is thousands of dollars per year on large balances.

Your savings are only working as hard as your interest rate. These tables show exactly how much you’ll earn at every major rate in 2026 — from big-bank rates to the best online accounts.

Annual Interest by Balance and APY

Balance	0.01% (Big Bank)	0.41% (Natl Avg)	4.00%	4.50% (Top HYSA)	4.75% (Best CD)
$1,000	$0.10	$4.10	$40	$45	$47.50
$5,000	$0.50	$20.50	$200	$225	$237.50
$10,000	$1	$41	$400	$450	$475
$25,000	$2.50	$102.50	$1,000	$1,125	$1,187.50
$50,000	$5	$205	$2,000	$2,250	$2,375
$100,000	$10	$410	$4,000	$4,500	$4,750
$250,000	$25	$1,025	$10,000	$11,250	$11,875

Monthly Interest by Balance and APY

Balance	0.41% (Natl Avg)	4.50% (Top HYSA)	4.75% (Best CD)
$5,000	$1.71	$18.75	$19.79
$10,000	$3.42	$37.50	$39.58
$25,000	$8.54	$93.75	$98.96
$50,000	$17.08	$187.50	$197.92
$100,000	$34.17	$375	$395.83

The Real Cost of a Low-Rate Account

The annual difference between the national average (0.41%) and a top HYSA (4.50%):

Balance	Annual Loss from Low Rate
$10,000	$409/year
$25,000	$1,022/year
$50,000	$2,045/year
$100,000	$4,090/year

This is money you’re leaving on the table every year by not moving savings to a high-yield account. There is no risk — both accounts are FDIC insured to the same limits.

How to Calculate Your Savings Interest

Simple formula: Balance x APY = Annual interest

Example: You have $32,000 saved at 4.50% APY. $32,000 x 0.045 = $1,440/year = $120/month

With compounding: Most savings accounts compound daily — meaning each day’s interest is added to your balance, and the next day’s interest is calculated on the (slightly larger) balance. The APY figure already accounts for daily compounding, so using the APY in the simple formula gives you an accurate annual estimate.

After 3 years at 4.50% APY (compounding): $32,000 x (1 + 0.045)^3 = $36,480 (vs $36,000 without compounding)

Taxes on Savings Interest

Interest income from savings accounts is taxable as ordinary federal income. Example:

$32,000 at 4.50% APY = $1,440 in interest income
In the 22% federal tax bracket: $317 in federal taxes
After-tax interest: $1,123 ($93.58/month)

Tax mitigation options:

Roth IRA savings grow tax-free — but limited to $7,000/year contribution
Treasury bills are state-tax exempt
I Bonds defer federal tax until redemption (up to 30 years)
