Question
Why does 20% down matter?
A 20% down payment is a common threshold for avoiding private mortgage insurance on many conventional loans, though actual rules vary by lender and program.
Financial
Use OmniCalc's down payment calculator to estimate your down payment, resulting loan amount, cash to close, and whether you are likely below the common PMI threshold.
Down payment calculator
Use a target home price plus either a percent or fixed down payment to estimate upfront cash needs, resulting loan size, loan-to-value, and whether you are likely below the 20% PMI threshold.
Why this result matters
An upfront home-purchase planner that converts percent or fixed down payments into loan amount, cash to close, and PMI-threshold context. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.
This down payment calculator estimates down payment amount, loan amount, loan-to-value, closing costs, and total cash to close using either a percent or fixed down payment input. It stays distinct from mortgage and affordability pages by focusing on the upfront funding decision.
Formula and method
The calculator converts a percent or fixed down payment into a capped down payment amount, subtracts it from the home price to estimate loan amount, calculates loan-to-value, applies a closing-cost rate, and flags whether the result falls below a common 20% PMI threshold.
Example
If you are targeting a home price and know either the percent or dollar amount you can put down, the calculator helps estimate your loan size, closing cash needed, and how far you are from a 20% threshold.
