Solopreneur Runway & Burn Rate Calculator
The Solopreneur Runway & Burn Rate Calculator for May 2026 is a critical survival tool for navigating the “Higher-for-Longer” interest rate environment. As of May 15, 2026, headline inflation is holding at 3.8%, and utility costs have surged 17.9% year-over-year, meaning your “burn” is likely higher than it was last spring.
With the One Big Beautiful Bill Act (OBBBA) now in full effect, your runway is no longer just about cash—it’s about optimizing your “Safe to Spend” liquidity.
1. The 2026 Burn Rate Formula
Your Burn Rate is the total amount of cash you spend each month to keep your business and life running.
$$\text{Monthly Burn} = (\text{Essential Business OpEx} + \text{Personal Survival Floor}) \times 1.038$$
- Essential Business OpEx: Software, insurance, and marketing.
- Personal Survival Floor: Housing, food, and the current $4.51/gal average gas price.
- The 1.038 Multiplier: This accounts for the 3.8% inflation currently eroding your purchasing power.
2. Calculating Your “Runway”
Your Runway is how many months you can survive if your revenue drops to zero today.
$$\text{Runway (Months)} = \frac{\text{Liquid Cash Assets}}{\text{Monthly Burn}}$$
| Asset Class | 2026 “Liquidity” Rating | May 2026 Yield |
| HYSA (e.g., Axos Bank) | High (1-2 days) | 4.21% APY |
| 12-Month CD | Low (Penalty for early exit) | 4.85% APY |
| S&P 500 (at 7,501) | Medium (3 days / Market Risk) | +14.8% (YoY) |

Frequently Asked Questions
1. Should I keep my runway cash in the S&P 500? With the market at 7,501, the upside is enticing, but the risk of a 10% correction is real. For “Runway” cash (your survival money), stick to a 4.21% HYSA. Keep your “Investment Surplus” in the market.
2. How does the 3.8% inflation affect my runway? If your runway is 12 months today, it will only be 11.5 months next year if you don’t earn any interest. This is why using a high-yield account is mandatory in 2026.
3. What is the “Trump Account” grant? For solopreneur parents, the $1,000 federal seed grant for these new accounts is “found money” for your family’s long-term runway (education/legacy).
