Showing first 12 of 36 periods

1

Origination Fee

= $1,000

One-time upfront fee deducted from loan proceeds. You borrow $50k but receive $49k if fee is 2%. SBA 7(a) loans: 0.5–3.5% depending on amount.

2

Net Proceeds

= $49,000

What actually hits your account. Use this for ROI analysis — not the face value of the loan.

3

Monthly Payment (PMT formula)

= $1,578.38

r = 0.7083% per period, n = 36 periods. Standard amortizing loan formula — early payments are mostly interest.

4

Total Amount Paid

= $56,822

Every dollar out of pocket over the life of the loan, before accounting for the origination fee.

5

Total Interest Cost

= $6,822

The pure cost of borrowing. Shorter terms and extra payments dramatically reduce this number.

6

Total Cost of Capital

= $7,822

The complete all-in cost of the loan. This is the hurdle your investment must clear to justify borrowing.

7

True APR (Newton-Raphson)

= 0.10%

APR includes the origination fee — always higher than the stated interest rate. Required by Truth in Lending Act (TILA) for consumer loans.

8

Total Expected Revenue Increase

= $108,000

What you expect the loan investment to generate over its term. Conservative estimates are safer — use your worst-case scenario.

9

Net Benefit

= $100,178

Positive — the loan generates more revenue than it costs. Proceed if revenue estimates are reliable.

10

ROI on Loan Cost

= 12.81%

Return on the cost of capital. Target 100%+ (loan generates 2× its cost). Below 0% means the loan destroys value.

11

Break-Even Month

= Month 3

How many months until cumulative revenue covers total loan cost. Should be well within the loan term.
