How this instrument works
The Economic Injury Disaster Loan is a direct loan from the U.S. Treasury, channeled through the Small Business Administration straight to a business or nonprofit that could show it lost revenue or working capital because of a declared disaster — the COVID-19 pandemic being by far the largest activation of the program in its history. That structure sets it apart from an ordinary SBA 7(a) loan, where a bank originates the credit and the SBA only guarantees part of it: here the SBA itself is the lender, and the rate on the note was fixed by regulation rather than negotiated with a loan officer.
That fixed rate is also two-tiered rather than risk-priced: 3.75% for a for-profit small business and 2.75% for a private nonprofit, regardless of the borrower's credit history, collateral, or cash flow — the toggle in this instrument is what selects between them. Both figures sat well under what a commercial lender would have charged a small business with uncertain revenue in the middle of a pandemic, because the loan existed to keep an operation solvent through a disaster it did not cause, not to price a lender's risk the way an ordinary bank loan does.
This sheet prices the amortization arithmetic only — principal and interest across the chosen term — and leaves out two things borrowers often fold into the same number. One is the separate EIDL Advance, grant money of up to $10,000 credited early in the program that never had to be repaid and does not appear anywhere in this payment. The other is deferment: SBA pushed the first payment due date out repeatedly during the pandemic, in some cases past two years from the date on the note, so an actual borrower's first real bill can land later than a standard amortization schedule alone would suggest. The COVID-19 EIDL program has since closed to new applications, so this calculation now mainly serves existing borrowers checking their own note, or anyone studying how the program's terms compared with ordinary business credit.
- Enter the amount financed under Loan amount, $ — the figure on the EIDL note itself, not including any separate Advance grant.
- Set Nonprofit organization (1=yes, 0=no) to 1 for a private nonprofit borrower or 0 for a for-profit business; this alone switches the applicable rate.
- Enter Loan term, years — EIDL notes ran as long as 30 years, longer than most conventional business term loans.
- Read Applicable rate, % to confirm which of the program's two fixed rates applied, then check Monthly payment for the exact installment.
- Flip the nonprofit toggle with the same loan amount and term held constant to see the gap between the two published rates in dollar terms.
Worked example — a $150,000 EIDL note over 30 years
Take a $150,000 loan (Loan amount, $) to a for-profit small business (Nonprofit organization set to 0) on a 30-year term (Loan term, years) — the combination the program used often for larger COVID-19 EIDL notes. Applicable rate, % resolves to 3.75%, so i = 3.75 ÷ 1200 = 0.003125 and N = 360 monthly payments. Working the amortization formula through those numbers gives Monthly payment = $694.67, the figure this sheet returns for exactly these inputs.
Switch only the nonprofit toggle to 1 and the same $150,000 over the same 30 years reprices at 2.75%, dropping the payment to $612.36 a month — about $82 less, purely from the rate the entity type unlocked. Over the full 360-payment term that gap compounds to about $29,632, a difference owed entirely to organizational status rather than anything about the loan amount or the disaster the loan responded to.
Questions
Why does the nonprofit toggle change the rate instead of my credit score?
Because the EIDL rate was never underwritten per borrower — SBA fixed it in regulation at 3.75% for for-profit small businesses and 2.75% for private nonprofits, full stop. A borrower's credit history, time in business, or existing debt could affect approval and loan size, but never moved the rate itself once approved, which is why flipping the Nonprofit organization field is the only thing in this sheet that changes Applicable rate, %.
Is the EIDL Advance the same thing as this loan?
No — the EIDL Advance was a separate grant of up to $10,000, paid out early in the pandemic to applicants who requested it, and it never had to be repaid regardless of whether the underlying loan was later approved. This calculator prices only the loan itself; if an Advance was received, it reduced how much cash was actually needed from the loan but does not appear in the payment math here.
Can I still apply for a new COVID-19 EIDL loan?
No. SBA stopped accepting new COVID-19 EIDL applications once program funding was exhausted, and the program is closed. This instrument is now most useful to existing borrowers checking their own note's arithmetic, or to anyone studying how the program's fixed, two-tier rate compared with market-priced small-business credit.
Why is a 30-year term available on a business loan at all?
Because EIDL was disaster relief rather than conventional underwriting, SBA let qualifying borrowers stretch loans out to as long as 30 years — well beyond the 5-to-10-year terms typical of an SBA 7(a) working-capital loan or a bank term loan. The longer term lowers Monthly payment directly, since the same balance spreads across more installments, though it also means paying the fixed rate for longer.
Does this figure include the deferment period before my first payment was due?
No — this is the steady-state monthly amount once payments began, not a schedule of when they started. SBA extended first-payment deferment on COVID-19 EIDL loans several times during the pandemic, in some cases past two years from the note date, so a given borrower's first real bill can land well after this figure alone would suggest on a standard amortization calendar.
Why is this rate so much lower than a bank would charge my business?
Because the rate reflects disaster relief, not risk. A bank prices a small-business loan against the borrower's likelihood of default; SBA fixed the EIDL rate by regulation for every qualifying borrower regardless of individual risk, which is why 3.75% (or 2.75% for a nonprofit) sat well under typical commercial small-business lending rates throughout the pandemic, and why it should not be read as a benchmark for what a bank would offer today.
