How This Calculator Works
Enter the startup capital you need, the rate a savings account pays, and how long until you want to launch. The calculator solves for the monthly contribution that reaches the target, with the small amount of interest earned shown separately.
The Formula
Required Monthly Saving (Sinking Fund)
FV = goal amount, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
Saving $50,000 over 3 years at a 3% savings rate needs about $1,329 a month. Deposits cover roughly $47,850 of the target; the remaining $2,150 comes from interest along the way. Versus a startup loan at 10% APR, the savings route avoids years of monthly payments competing with the business's cash flow.
Key Insight
Self-funded startups have an underrated advantage: every dollar of revenue stays with the founder, not a lender or an investor. The savings approach takes longer to launch but produces a business with no debt service and full equity — a meaningfully better outcome for small businesses that will not raise venture capital.

Frequently Asked Questions
What should the startup capital cover?
Equipment, inventory, legal setup, marketing, deposits, and 6 to 12 months of operating runway. Underfunding the runway is the fastest way to put a new business under financial pressure in the first year.
Is it better to save or borrow?
Saving avoids debt service competing with early revenue — a real advantage for businesses that will not raise outside capital. Borrowing makes sense when timing matters more than minimizing fixed costs.
What return should I assume?
Use a conservative savings or high-yield savings rate for funds held for under 3 years. Longer horizons can use a slightly higher figure, but startup capital usually sits in cash, not the market.
Should I keep these savings separate?
Yes. A dedicated high-yield savings account makes progress visible and keeps the fund harder to dip into. Many founders also open a business bank account before launch to receive the savings on day one.
What if the launch date slips?
Re-run the calculator with a later date. A longer horizon usually lets you lower the monthly deposit. The bigger risk is rushing to launch before the capital is fully saved — a thin first year burns through savings faster than expected.
When is this calculator unreliable?
Less reliable when industry-specific licensing substantial varies, when financing options (SBA loans, lines of credit, angel/VC) substantially change cost, when personal runway separate from business reserve, when franchise FDD review substantial, when tax structure (LLC vs S-Corp vs C-Corp) affects costs, when inventory + working capital cycle, or when marketing + customer acquisition cost not modeled. Failure rates substantial — Year 5 ~50%.
