An SBA 7(a) payment is M = P·i/(1−(1+i)^−n) — the amount financed, the monthly rate, and the number of payments. What makes a 7(a) different is the rest: a variable rate quoted as prime plus your lender's spread, an upfront guarantee fee charged on the guaranteed portion rather than the whole loan, and a term that depends on what the money buys — ten years for working capital and equipment, twenty-five for owner-occupied real estate.

Commercial real estate runs up to 25 years.

At $500,000 the framework allows a spread of up to about 3.00% over the base rate (Above $350,000). Your spread is inside it.

Rates, fee tiers and guarantee percentages are set by SBA policy and move. Every one of them is editable above — treat the defaults as a starting assumption, not a quote, and check them against your term sheet. Guaranteed portions are capped at $3.75M.
It is an ordinary bank loan with an unusual backstop. You borrow from a bank or a non-bank lender, you repay that lender, and the Small Business Administration lends you nothing at all — it simply promises the lender that if the business fails, the government will cover most of the loss. That promise is what turns a decline into an approval, and everything odd about the programme follows from it.
Six steps take you from a term sheet to the two numbers that matter: what leaves your account each month, and what the money really costs. The first two are the ones no ordinary loan calculator does.
The SBA guarantees a share of the loan, and the share is larger on small loans. Multiply the gross loan P by that percentage to get the base the fee is charged on. Missing this step is the single most common way people overstate the fee.
Each tier charges its own percentage, and on the largest tier the guaranteed portion splits at a million dollars with a higher rate above the split. Add the bands together for the upfront fee F.
Pay the fee at closing and the payment is calculated on the loan itself. Roll it in and the principal grows by F, so every future payment carries it. Both are allowed; the choice is a cash-flow one.
A 7(a) note is usually variable: the rate is a published base rate plus your lender’s spread, and the spread is capped by loan size. Divide the total by twelve for the monthly rate i, and multiply the term by twelve for n.
The payment M is the one figure that drives the balance to exactly zero on the final payment. Multiply it by n for everything you hand back, and subtract P for the interest.
Interest is not the only cost. The guarantee fee is a real charge whether you wired it at closing or borrowed it, so the honest total cost of the loan is interest plus F.
Almost every wrong answer about SBA costs comes from multiplying the whole loan by the headline fee percentage. The fee is charged on the slice the SBA actually guarantees, and that slice is a larger share of a small loan than of a big one — so the fee does not scale in a straight line with the money you borrow.
| Gross loan | SBA guarantees | Fee on the guaranteed portion | Example loan | Guaranteed | Fee | Share of the loan |
|---|---|---|---|---|---|---|
| $150,000 or less | 85% | 2.00% | $150,000 | $127,500 | $2,550.00 | 1.70% |
| $150,001 – $700,000 | 75% | 3.00% | $500,000 | $375,000 | $11,250.00 | 2.25% |
| $700,001 – $5,000,000 | 75% | 3.50% to $1M, then 3.75% | $1,500,000 | $1,125,000 | $39,687.50 | 2.65% |
| — same tier — | 75% | 3.50% to $1M, then 3.75% | $5,000,000 | $3,750,000 | $138,125.00 | 2.76% |
Guaranteed exposure on any one loan is capped at $3,750,000, which is why the $5,000,000 row guarantees $3,750,000 rather than a straight 75%. Every tier here is set by SBA policy notice and is revised from time to time — the calculator above takes an override so a live term sheet always wins.
Both are allowed, and the difference is larger than it looks because a financed fee is carried for the whole term.
| Settlement | Cash at closing | Amount financed | Usable proceeds | Monthly | Total interest | Whole cost |
|---|---|---|---|---|---|---|
| Fee paid in cash | $11,250.00 | $500,000 | $488,750 | $4,720.91 | $916,273 | $927,523 |
| Fee financed | $0.00 | $511,250 | $500,000 | $4,827.13 | $936,889 | $948,139 |
$500,000 at 10.50% over 25 years. Financing the $11,250.00 fee adds $106.22 to every payment and $20,616 of extra interest — so the deferred fee ends up costing $31,866 in total.
One tab per use of proceeds, each worked from the guaranteed portion down to the payment, with the alternative term shown alongside. Switch tabs to watch the fee tier change with the loan size and the term change with what the money buys.
| Term | Payment | Total interest |
|---|---|---|
| 25 years (this tab) | $14,162.73 | $2,748,818 |
| 10 years | $20,240.25 | $928,830 |
The guaranteed portion here clears a million dollars, so the fee splits across two bands. And the twenty-five-year term is the reason a property purchase is the one 7(a) loan whose payment feels affordable. Stretching this loan from 10 years to 25 moves the interest bill by $1,819,988.
The term is set by what the money buys, not by what you would prefer, and it moves the payment more than the rate does. A property earns the twenty-five-year schedule because a building outlives everything else a business owns; payroll and machinery do not.
On $500,000 at 10.50%, the twenty-five-year schedule cuts the monthly payment by 30% — from $6,746.75 to $4,720.91 — and multiplies the lifetime interest by 3.0×, from $309,610 to $916,273. That is the honest trade: a payment your cash flow can carry, bought with $606,663 of extra interest. It is the right trade when the alternative is a payment you cannot make, and the wrong one when you could have carried the shorter schedule all along.
| Use of proceeds | Maximum term | What the money buys | Why the term is capped there |
|---|---|---|---|
| Working capital | 10 years | Payroll, inventory, marketing, a cash-flow cushion, day-to-day operating expense. | Working capital is consumed inside a business cycle, so the loan is written to be repaid over roughly a decade rather than stretched across a generation. |
| Equipment | 10 years | Machinery, vehicles, kitchen fit-out, computers, production lines, furniture. | The term is tied to the useful life of the asset. Ten years is the usual ceiling; a shorter-lived machine gets a shorter loan. |
| Commercial real estate | 25 years | Buying, building or renovating an owner-occupied commercial property. | A building outlives every other thing a business buys, so the programme allows the longest term here — and it is the single biggest lever on the monthly payment. |
| Business acquisition | 10 years | Buying an existing business, buying out a partner, or funding goodwill. | Goodwill has no useful life to hang a term on, so acquisition loans run on the ten-year schedule unless real estate comes with the deal. |
On $500,000 at 10.50%, the ten-year schedule costs $6,746.75 a month and $309,610 of interest; the twenty-five-year schedule costs $4,720.91 and $916,273. That is $606,663 of extra interest bought with a 30% smaller payment.
Most 7(a) loans are variable. The note is quoted as a base rate — usually the prime rate — plus a spread your lender negotiates, and the SBA caps how wide that spread may be. The cap is generous on small loans, because underwriting a small loan costs the lender almost as much as underwriting a large one.
| Loan size | Maximum spread over the base rate |
|---|---|
| $50,000 or less | +6.50% |
| $50,001 – $250,000 | +6.00% |
| $250,001 – $350,000 | +4.50% |
| Above $350,000 | +3.00% |
| If prime rises | Note rate | Payment | Change |
|---|---|---|---|
| today | 10.50% | $4,720.91 | — |
| +1 points | 11.50% | $5,082.34 | +$361.44 |
| +2 points | 12.50% | $5,451.77 | +$730.86 |
| +3 points | 13.50% | $5,828.22 | +$1,107.32 |
Rate shock on $500,000 over 25 years from a 10.50% starting rate. Three points of prime take the payment from $4,720.91 to $5,828.22 — a rise of 23.5%.
The payment is level, but its split is not. Interest is charged on the balance outstanding, and on a twenty-five-year loan that balance barely moves for years — which is why the first payments are almost pure interest and why an early overpayment is worth so much more than a late one.

Pick a loan size and read the monthly payment — or the total interest, or everything you repay — at every rate from 7.50% to 14.50% across six terms. Because a 7(a) rate is prime plus a spread, the useful range here is wider than a fixed-rate table would need.

Figures are on the amount financed and exclude the guarantee fee. Add the fee separately, or use the calculator at the top of the page to fold it into the loan. Terms beyond ten years are available only for owner-occupied commercial real estate.
The programme is unusually broad — it is the reason the 7(a) exists rather than a stack of narrow products — but the exclusions are firm, and a lender will ask for a use-of-proceeds breakdown before it asks for anything else.
A mixed-use loan is normal — a property purchase alongside working capital, say — and the lender then blends the term across the two uses rather than granting the full 25 years on the whole facility.
Seven tests sit between an application and an approval. None of them is about the payment you can afford — that is the lender's own credit analysis — and every one of them is checked before the file goes anywhere near underwriting.
The 7(a) is the default, but it is not always the right door. Pick on what the money is for, how fast you need it, and whether a fixed rate matters more than flexibility.
| Programme | What it funds | Size | Term | Rate | Speed |
|---|---|---|---|---|---|
| 7(a) | Working capital, equipment, acquisitions, owner-occupied real estate, debt refinance — the general-purpose programme. | Up to $5 million | 10 years typical; 25 for real estate | Usually variable: a base rate plus a capped lender spread | Weeks to a few months |
| 504 | Fixed assets only — owner-occupied buildings and heavy, long-lived equipment. Not working capital. | Debenture up to $5 million, more for some manufacturing and energy projects | 10, 20 or 25 years on the debenture | Fixed, tied to the bond market at the time the debenture sells | Slowest — three parties to a deal |
| Microloan | Small working-capital and equipment needs, often for very new or very small businesses. | Up to $50,000 | Up to about 7 years | Set by the non-profit intermediary; typically above 7(a) | Fast — weeks |
| SBA Express | Working capital and lines of credit where speed matters more than size. | Up to $500,000 | Up to 10 years; lines of credit shorter | Variable, with a wider allowable spread than standard 7(a) | Fastest — the SBA responds to the lender within days |
Programme ceilings and terms are set by the SBA and revised periodically. For a conventional comparison, price the same money as an ordinary amortizing loan or a personal loan and compare the whole cost, fee included.
A 7(a) loan is a simple-interest loan, so every extra dollar of principal stops accruing interest immediately. The one catch is a declining charge that attaches to long terms only, and only to large lump-sum prepayments in the first three years.
| Payoff in | Charge | Balance then | Charge in dollars |
|---|---|---|---|
| Year 1 | 5% | $495,643 | $24,782.17 |
| Year 2 | 3% | $490,807 | $14,724.20 |
| Year 3 | 1% | $485,437 | $4,854.37 |
| Year 4 onwards | 0% | — | nothing |
On $500,000 at 10.50% over 25 years. Terms under 15 years carry no charge, and prepayments up to 25% of the outstanding balance in a year are free even on a long term.
None of these appear in the headline rate, and each of them can be worth more than a point of interest.
