How the comparison works
On the defaults — $10,000.00 in, a 0.07% checking APY and a 4.00% savings APY, 1.0 years, a $12.00 monthly checking fee — the checking account ends at $10,007.00 before fees and $9,863.00 after them, and the savings account ends at $10,400.00, so SAVINGS wins by $537.00. The checking account earns $7.00 of interest and pays $144.00 in fees; the savings account earns $400.00 and pays no fee. APY is the effective annual yield — it already includes compounding, so the future value is simply the deposit times (1 + APY) raised to the term in years. The checking fee is charged every month for the whole term, even on a $0 balance — the model shows a negative checking net for a $0 deposit, it does not hide it. The fee is what decides this comparison at small deposits, not the interest rate: the checking account would need a 5.44% APY just to tie, and a fee-free checking account still loses by $393.00. Taxes are NOT included — both accounts are taxed the same way, so the winner does not change.
The worked example, line by line
Setup: $10,000.00 in, checking 0.07%, savings 4.00%, 1.0 years, $12.00/mo checking fee.
Line 1 — the checking value. $10,000.00 × 1.0007 = $10,007.00; interest $7.00.
Line 2 — the checking fees. $12.00 × 12 × 1 = $144.00.
Line 3 — the checking net. $10,007.00 − $144.00 = $9,863.00 — the checking account ends below the deposit.
Line 4 — the savings value. $10,000.00 × 1.04 = $10,400.00; interest $400.00; no fee, so the net is $10,400.00.
Line 5 — the gap. $10,400.00 − $9,863.00 = $537.00 — SAVINGS wins by $537.00. The default result in full: Checking $10,007.00 (interest $7.00, fees $144.00, net $9,863.00) | Savings $10,400.00 (interest $400.00, net $10,400.00) | SAVINGS wins by $537.00.
Line 6 — the rounding convention. Rounding convention: totals are computed from unrounded values, so rounded parts may differ by a cent from their rounded sum — and every gap on this page is the difference of the displayed totals: each side is rounded to cents first, then subtracted. On these defaults the unrounded gap and the displayed gap agree at $537.00, but on other inputs they can differ by a cent, and the page always shows the displayed figure.
Every branch, checked
Deposit $25,000: Checking $25,017.50, net $24,873.50; Savings $26,000.00, SAVINGS wins by $1,126.50. A bigger deposit makes the same rate gap worth more dollars — and the $144.00 fee matters less.
Deposit $1,000: Checking $1,000.70, net $856.70; Savings $1,040.00, SAVINGS wins by $183.30. On a small deposit the $144.00 fee eats the checking account alive — it ends $143.30 below what was put in.
Checking APY 0.50%: Checking $10,050.00, net $9,906.00; Savings $10,400.00, SAVINGS wins by $494.00. A checking rate seven times the default still cannot cover the fee.
Savings APY 5.00%: Checking $10,007.00, net $9,863.00; Savings $10,500.00, SAVINGS wins by $637.00. A full point of extra savings yield adds exactly $100.00 to the gap.
Checking monthly fee $0: Checking $10,007.00, net $10,007.00; Savings $10,400.00, SAVINGS wins by $393.00. A fee-free checking account changes the answer — but only from $537.00 to $393.00, because the rate gap alone is worth $393.00.
Term 5 years: Checking $10,035.05, fees $720.00, net $9,315.05; Savings $12,166.53, SAVINGS wins by $2,851.48. Give the rate gap five years to compound and the $720.00 of fees, and the checking account ends nearly $685.00 below the deposit.
The reverses, worked backwards
Checking APY for a TIE: exact 5.4400%; displayed 5.44% → checking net $10,400.00, gap $0.00, TIE. At 5.44%: Checking $10,544.00 (interest $544.00, fees $144.00, net $10,400.00) | Savings $10,400.00 (interest $400.00, net $10,400.00) | Tie. At 5.43%: Checking $10,543.00 (interest $543.00, fees $144.00, net $10,399.00) | Savings $10,400.00 (interest $400.00, net $10,400.00) | SAVINGS wins by $1.00 — the gap is $1.00. This reverse is CONTINUOUS: the gap moves smoothly with the rate, so there is no smallest step that flips it — the displayed value is simply the rounded answer. The star is a PERCENT.
Deposit for a $1,000 gap: exact $21781.1705; displayed $21,781.17 → gap $1,000.00. At $21,781.17: Checking $21,796.42 (interest $15.25, fees $144.00, net $21,652.42) | Savings $22,652.42 (interest $871.25, net $22,652.42) | SAVINGS wins by $1,000.00. One dollar less, $21,780.17: Checking $21,795.42 (interest $15.25, fees $144.00, net $21,651.42) | Savings $22,651.38 (interest $871.21, net $22,651.38) | SAVINGS wins by $999.96 — the gap is $999.96. The displayed gap is $22,652.42 − $21,652.42 = $1,000.00, and the unrounded gap at the exact deposit is exactly $1,000.00 too. This reverse is CONTINUOUS. The star is DOLLARS.
Term for a $2,000 gap: exact 3.5836 years; displayed 3.58 years → gap $1,997.90. At 3.58 years: Checking $10,025.08 (interest $25.08, fees $515.52, net $9,509.56) | Savings $11,507.46 (interest $1,507.46, net $11,507.46) | SAVINGS wins by $1,997.90. At 3.57 years: Checking $10,025.01 (interest $25.01, fees $514.08, net $9,510.93) | Savings $11,502.94 (interest $1,502.94, net $11,502.94) | SAVINGS wins by $1,992.01 — the gap is $1,992.01. This reverse is CONTINUOUS. The star is YEARS.
Monthly fee that eats exactly the year's checking interest: exact $0.5833/mo; displayed $0.58/mo → fees $6.96, checking net $10,000.04. At $0.58/mo: Checking $10,007.00 (interest $7.00, fees $6.96, net $10,000.04) | Savings $10,400.00 (interest $400.00, net $10,400.00) | SAVINGS wins by $399.96 — $0.04 of the $7.00 interest is left. At $0.57/mo: Checking $10,007.00 (interest $7.00, fees $6.84, net $10,000.16) | Savings $10,400.00 (interest $400.00, net $10,400.00) | SAVINGS wins by $399.84. This reverse is CONTINUOUS. The star is DOLLARS/MONTH.
Savings APY for a $500 gap: exact 3.6300%; displayed 3.63% → savings FV $10,363.00, gap $500.00. At 3.63%: Checking $10,007.00 (interest $7.00, fees $144.00, net $9,863.00) | Savings $10,363.00 (interest $363.00, net $10,363.00) | SAVINGS wins by $500.00. At 3.62%: Checking $10,007.00 (interest $7.00, fees $144.00, net $9,863.00) | Savings $10,362.00 (interest $362.00, net $10,362.00) | SAVINGS wins by $499.00 — the gap is $499.00. This reverse is CONTINUOUS. The star is a PERCENT.
Deposit where the checking net equals the deposit: exact $205714.2857; displayed $205,714.29 → checking net $205,714.29 (= the deposit). At $205,714.29: Checking $205,858.29 (interest $144.00, fees $144.00, net $205,714.29) | Savings $213,942.86 (interest $8,228.57, net $213,942.86) | SAVINGS wins by $8,228.57. One dollar less, $205,713.29: Checking $205,857.29 (interest $144.00, fees $144.00, net $205,713.29) | Savings $213,941.82 (interest $8,228.53, net $213,941.82) | SAVINGS wins by $8,228.53 — the checking net is still exactly the deposit, $205,713.29, so one dollar less rounds to the same displayed figure: this reverse is exact, not a step. This reverse is CONTINUOUS. The star is DOLLARS.
What the defaults assume
Both accounts are taxed the same way, so taxes are NOT included and the winner does not change. With no deposit at all (Checking $0.00 (interest $0.00, fees $144.00, net -$144.00) | Savings $0.00 (interest $0.00, net $0.00) | SAVINGS wins by $144.00) the checking account still charges $144.00 of fees and ends at -$144.00 — a model-level outcome, not an error: the fee is charged every month for the whole term, even on a $0 balance. With no term at all (Checking $10,000.00 (interest $0.00, fees $0.00, net $10,000.00) | Savings $10,000.00 (interest $0.00, net $10,000.00) | Tie) both sides are $10,000.00 — a TIE, because no time has passed for interest to accrue or fees to be charged. With equal APYs of 4.00% (Checking $10,400.00 (interest $400.00, fees $144.00, net $10,256.00) | Savings $10,400.00 (interest $400.00, net $10,400.00) | SAVINGS wins by $144.00) the savings account wins by exactly the $144.00 fee — the fee alone. With a $25.00 monthly fee (Checking $10,007.00 (interest $7.00, fees $300.00, net $9,707.00) | Savings $10,400.00 (interest $400.00, net $10,400.00) | SAVINGS wins by $693.00) the checking account ends $293.00 below the deposit. With a savings account that pays nothing (Checking $10,007.00 (interest $7.00, fees $144.00, net $9,863.00) | Savings $10,000.00 (interest $0.00, net $10,000.00) | SAVINGS wins by $137.00) the savings account still wins by $137.00 — the fee alone is bigger than the checking account’s $7.00 of interest. With a checking account that pays nothing (Checking $10,000.00 (interest $0.00, fees $144.00, net $9,856.00) | Savings $10,400.00 (interest $400.00, net $10,400.00) | SAVINGS wins by $544.00) the gap is $544.00. Rounding convention: totals are computed from unrounded values, so rounded parts may differ by a cent from their rounded sum — and every gap on this page is the difference of the displayed totals: each side is rounded to cents first, then subtracted.

Who uses this
- The saver with $10,000.00 for a year: they learn the savings account ends $537.00 ahead — and they check the fee-free branch, where the gap shrinks to $393.00 but the savings account still wins.
- The small-balance saver with $1,000.00: they learn the $144.00 fee leaves the checking account at $856.70, below the deposit — and they check the $0-deposit edge, where the fee still charges $144.00 and the checking net is -$144.00.
- The long-term saver with $25,000.00: they learn the savings lead grows to $1,126.50 over one year and $2,851.48 over five years — and they check the deposit reverse, where $21,781.17 makes the gap exactly $1,000.00.
- The checking-account shopper: they learn a checking account needs a 5.44% APY just to tie the savings account — and they check the equal-APY edge, where the $144.00 fee alone decides it.
Accuracy & limitations
The math is first-principles: future value = D·(1+APY)^n with annual compounding on the APY, interest = future value − deposit, checking fees = monthly fee × 12 × term, checking net = future value − fees, and the gap is the difference of the displayed totals — each side rounded to cents first, then subtracted. Every figure is rounded to cents half-up, totals are computed from unrounded values, so rounded parts may differ by a cent from their rounded sum. What the model cannot do is predict YOUR rates and fees: APYs change, banks pay different rates, and many checking accounts waive the monthly fee with a minimum balance or a direct deposit — a waived fee is the $0-fee branch, not a different model. Taxes are NOT included — both accounts are taxed the same way, so the winner does not change, but the after-tax gap is smaller than the pre-tax gap shown here. Use it to compare the two accounts on the same numbers, then check the real rate and fee schedule before you open either one.

Frequently asked questions
What do the defaults give?
SAVINGS wins by $537.00. On $10,000.00 at a 0.07% checking APY and a 4.00% savings APY for 1.0 years with a $12.00 monthly checking fee, the checking account earns $7.00 and pays $144.00 in fees, for a net of $9,863.00; the savings account earns $400.00 and pays no fee, for a net of $10,400.00. The gap is $537.00.
Why does the savings account win when the checking account pays interest too?
The fee decides it, not the rate. The checking account earns $7.00 of interest in a year and pays $144.00 in fees — twenty times what it earns. Even if the savings account paid nothing at all, it would still win by $137.00, because the fee alone is bigger than the checking account’s $7.00 of interest.
What checking rate would make it a tie?
5.44%. At a 5.44% checking APY the checking net is $10,400.00, exactly the savings net — a TIE. At 5.43% the checking net is $10,399.00 and the savings account is ahead by $1.00.
How much do I need to deposit for a $1,000 gap?
$21,781.17 (exact $21781.1705). At $21,781.17 the savings account reaches $22,652.42 and the checking net is $21,652.42, a gap of $1,000.00; at $21,780.17 the gap is $999.96. The displayed gap is $22,652.42 − $21,652.42 = $1,000.00, and the unrounded gap at the exact deposit is exactly $1,000.00 too.
How long until the gap reaches $2,000?
Exact 3.5836 years, displayed 3.58 years. At 3.58 years the gap is $1,997.90; at 3.57 years it is $1,992.01.
What monthly fee eats exactly the year's checking interest?
$0.5833 a month. At the displayed $0.58 a month the fees are $6.96 and the checking net is $10,000.04 — $0.04 of the $7.00 interest is left. At $0.57 a month the fees are $6.84 and the net is $10,000.16.
What if my checking account has no fee?
The savings account still wins, by $393.00. With a $0.00 monthly fee the checking net is $10,007.00 against the savings account’s $10,400.00. A fee-free checking account changes the answer — but only from $537.00 to $393.00, because the rate gap alone is worth $393.00.
What happens with a $0 deposit?
The checking net is -$144.00. The fee is charged every month for the whole term, even on a $0 balance, so the checking account ends at -$144.00 while the savings account is $0.00 — SAVINGS wins by $144.00. That is a model-level outcome, not an error: the calculator shows it rather than hiding it.
