Understanding Your Results
post money is the number to look at first, but it should not be read on its own. Whether the answer is high, low, good, bad, efficient, or expensive depends on the units, limits, and assumptions behind the pre and post money valuation calculation.
Useful result lines include Post Money, Investor Equity, Investment, Pre Money. Read them together instead of relying only on the first number.
If the answer is much higher or lower than expected, check the basics first: units, decimal places, percentages, date ranges, and whether each input belongs to the same case.

- Using the wrong unit for Investment.
- Pairing Investor's equity with a value from a different source, date range, or scenario.
- Missing a percentage sign, currency sign, date setting, or measurement suffix beside an input.
- Rounding an input too early, then using that rounded number again.

- Investor's equity works with Post-money valuation; changing either one can move post money.
- Post-money valuation works with Pre-money valuation; changing either one can move post money.
- Pre-money valuation works with the rest of the inputs; changing either one can move post money.

If the result affects borrowing, taxes, payroll, compliance, investment decisions, or a signed agreement, verify it with official documents or a qualified professional.
If you plan to share the answer, keep the inputs with it. That makes the pre and post money valuation calculation easier to check, repeat, or update later.
