Financial tools hub
Free Financial Tools Online
This hub is for decisions that should be tested before they become commitments: borrowing, repayment, cash burn, runway, depreciation, and long-term growth. The pages stay practical and keep the assumptions in view instead of dressing up the answer.
Use the borrowing tools when you are comparing terms, the cash tools when you want to know how long the business can keep moving, and the investment tools when you need a clearer view of future value. The goal is to keep the math close to the decision.
Where the decision usually starts
Loan and mortgage calculators tell you the shape of a payment. Debt payoff shows what extra payments can do. Cash runway and burn rate tell you how much room you really have when the business is under pressure.
Money workflow
Compare payment, payoff, investment, and affordability decisions in one path
Financial pages need extra clarity because users may act on the numbers. This hub emphasizes education, assumptions, and related checks before decisions become commitments.

- 1Calculate the payment or return.
- 2Check total cost, interest, or long-term impact.
- 3Read the guide before using the number for a real financial decision.
Trust standards
- No signup required for core tools
- Browser-first workflows where possible
- Clear examples, assumptions, and next steps

Contact editorial teamWhen cash matters more than the headline result
Run the cash runway calculator before hiring or adding fixed costs, and use the burn rate calculator when you want to check whether a period of spending was actually stable or just looked stable on the surface.
Recurring revenue and unit economics
Use these pages when the real question is not just whether the spend exists, but whether the payback is fast enough and the recurring base is holding. Payback tells you how quickly CAC comes back. MRR and churn tell you whether the revenue base is compounding or leaking.
A practical sequence
- 1Use cash runway and burn rate first so you know how much time you have to adjust.
- 2Use payback period to check whether each customer or campaign recovers cost quickly enough.
- 3Use MRR and churn to confirm the recurring base is compounding rather than shrinking.
- 4Use marketing ROI before you scale paid growth or lock in a fixed spend plan.
