What the Combination Mortgage calculator works out

The Combination Mortgage Calculator is a free, embeddable calculator from CalcFunnel. Compare a single mortgage with PMI against a first-plus-piggyback-second combination.

You enter 7 inputs: home price, down payment (%), first mortgage (% of price), first mortgage rate (%), second mortgage rate (%), PMI rate (% / yr) and loan term (years).

It returns combo monthly payment, single loan payment (w/ PMI), monthly savings with combo, first mortgage amount and second mortgage amount.

Built for loan officers, brokers and homebuyers. Embedding it on your own website is included on the Free plan (free forever for up to 5 calculators on one domain), as part of the Mortgage & Home Loans category.

Inputs

The inputs it uses

Each field below comes straight from the calculator, with the same help text visitors see when they hover the info icon.

Property & Down Payment

Home Price
The purchase price of the home.
Down Payment (%)
Your down payment as a percent of the home price. Below 20% a single loan usually requires PMI.

Rates & Structure

First Mortgage (% of Price)
The first mortgage as a percent of the home price. 80% keeps it at the PMI-free threshold; the rest beyond your down payment becomes the second mortgage.
First Mortgage Rate (%)
The interest rate on the first mortgage (also used for the single-loan scenario).
Second Mortgage Rate (%)
The interest rate on the piggyback second mortgage, usually higher than the first.
PMI Rate (% / yr)
Annual private mortgage insurance rate applied to the single-loan scenario when the down payment is below 20%.
Loan Term (years)
The repayment term applied to all loans in the comparison.
