finance.mortgage-option-pool Calculator
Calculates option pool size, dilution impact, and effective pre-money valuation in a mortgage and property investment context. Option pool shuffles are one of the most misunderstood VC terms — a required 15% option pool created pre-close reduces the effective pre-money by 15% of post-money valuation.
Inputs
Price
The agreed sale price of the home. Your down payment is typically a percentage of this figure.
Down
Cash paid upfront, reducing the amount you borrow. Putting down 20%+ typically eliminates private mortgage insurance (PMI).
Rate
The rate at which interest accrues. Small differences compound dramatically — compare carefully when choosing between lenders.
Term
Reference formula or conversion factor shown for context.
Results
loan amount
The principal borrowed — the starting balance before any interest accrues.
monthly payment
Fixed monthly instalment covering principal and interest. Does not include property tax or insurance unless explicitly shown.
total paid
Sum of all payments made — principal plus all interest. Subtract the loan amount to see the pure interest cost.
total interest
Cumulative interest paid over the loan term. Paying even a little extra each month toward principal can save tens of thousands.
