About the WACC Simulator
Weight the cost of equity and after-tax cost of debt to get the weighted average cost of capital — the discount rate behind every valuation.
It's built for directional planning: change any assumption and watch the whole projection move, the way a seasoned operator pressure-tests a plan before committing capital. Everything is computed live in your browser — nothing is sent anywhere.
How the WACC Simulator Works
The model takes 5 assumptions and returns 3 headline metrics plus a full breakdown. Here is exactly what goes in and what comes out — no black box.
The Inputs
| Assumption | Example value |
|---|---|
| Equity value | $8,000,000 |
| Debt value | $2,000,000 |
| Cost of equity | 12% |
| Cost of debt | 7% |
| Tax rate | 21% |
Worked Example
Every figure below is produced by the live model using the example assumptions above. Change any input in the simulator to see your own numbers.

The Operator's Read
Debt is cheaper than equity — and tax-deductible — so more leverage lowers WACC, up to a point. Beyond it, rising financial risk pushes both costs up. WACC is the hurdle every project and valuation must clear. Educational only.
Assumptions & Limitations
- •The model is deterministic: it projects your inputs forward with clear arithmetic, not a Monte-Carlo or probabilistic forecast. It shows one scenario at a time — run several to bracket a range.
- •Defaults are illustrative benchmarks, not your business. Replace every field with your real numbers before drawing conclusions.
- •It abstracts away taxes, financing, seasonality, and one-off events unless a field explicitly captures them. Treat the output as a directional estimate.
- •This is an educational tool, not financial, investment, tax, or legal advice. Validate real decisions with a qualified professional.
Frequently Asked Questions
What does the WACC Simulator calculate?
Weight the cost of equity and after-tax cost of debt to get the weighted average cost of capital — the discount rate behind every valuation. It takes 5 assumptions — Equity value, Debt value, Cost of equity, Cost of debt, Tax rate — and returns WACC, Equity weight, Debt weight, along with a full projection table you can export.
How do I use the WACC Simulator?
Enter your own figures in the input fields above — Equity value, Debt value, Cost of equity, and the rest. The model recalculates instantly and shows the resulting WACC and full breakdown. No sign-up needed to run it.
Is the WACC Simulator free?
Yes — you can run the simulator and see the headline results for free. Toolkit Pro unlocks the full projection table, Excel/PDF export, saved scenarios, and AI analysis: $180/mo, $1,728/yr, or unlock any 3 simulators for $20.
What's the difference between this and a free calculator?
A calculator answers one question. This simulator models the full picture — multiple linked assumptions, a projection table, and scenario comparison — the way an operator would build it in a spreadsheet, but instantly.
Who built the WACC Simulator?
The Crimson Bench's Ivy League-educated operators — the same people we deploy into C-suites. This is the self-serve version of a model they'd build inside a live engagement.
Is this financial advice?
No. The WACC Simulator is an educational modeling tool for directional planning — not financial, investment, tax, or legal advice. Validate any real decision with a qualified professional.
