Interest accrues daily (annual rate ÷ 365 × days in period). Payment dates falling on Saturday shift +2 days to Monday; Sunday shifts +1 day — those extra days continue accruing interest and are reflected in that period's interest column. Extra principal payments reduce the balance immediately, shortening the loan term; the summary shows how much interest and how many months are saved.
Frequently Asked Questions
What interest rates should I use?
For SBA 7(a) loans, current rates are Prime + 2.25–4.75% (roughly 10–12.5% as of 2026). Conventional bank loans for strong borrowers start around 7–9%. Online lenders and fintech products range from 12–40%+ depending on risk.
How does loan term affect my DSCR?
Longer terms mean lower monthly payments, which improves your DSCR. A $500,000 loan at 9% over 10 years runs about $6,300/month; over 25 years it's about $4,200/month. The tradeoff is substantially more total interest paid.
What is a typical SBA 7(a) loan term?
Working capital loans: up to 10 years. Equipment loans: up to 10 years. Commercial real estate: up to 25 years.
