MortDrop is a free mortgage and loan payoff calculator built for homeowners, first-time buyers, and anyone who wants to understand the true cost of their home loan — with no ads, no paywall, and no account required.
Compute monthly payments for conventional, FHA, VA, USDA, and jumbo loans instantly.
See exactly how extra payments, lump sums, and bi-weekly schedules shorten your loan and save interest.
Model long-term wealth outcomes for renting versus owning with your real numbers.
Understand how ±0.5% and ±1% rate changes affect your payment and total cost.
MortDrop is designed for anyone navigating one of the biggest financial decisions of their life. Whether you're a first-time buyer comparing loan programs, a current homeowner wondering if extra payments are worth it, or a renter deciding whether to keep renting or take the plunge into ownership — MortDrop gives you clear, honest numbers in seconds.
The calculator runs entirely in your browser. Loan amounts, rates, terms and every other figure you type are processed on your own device. They are never transmitted to us and never stored on our servers. You can use the whole calculator without giving us anything at all, and without creating an account.
The one exception is the optional “Connect Me With an Expert” form. If you choose to fill it in, we collect the contact details you enter and a record of your consent. That form is entirely your choice, and nothing else on MortDrop depends on it.
We're upfront about this because you deserve to know before you decide whether to use the form. If you submit the connect form, we share your details with licensed mortgage lenders, brokers, or real estate professionals, and they pay us for that referral. That is how a free, ad-free calculator stays free.
We do not sell your information to unrelated marketing lists, data brokers, or ad networks. And we never charge you anything — you are not the customer of the referral, the lender is.
The calculator's maths doesn't change based on whether you fill in the form. The amortisation, PMI, and payoff figures are computed from your inputs alone. But you should know we have a commercial interest in referrals, so treat our tool as one input among several — not as impartial advice. We are not a bank, a lender, or a mortgage broker, and we do not originate loans.
MortDrop is an independent project built by developers who believe financial tools should be simple, transparent, and free to use. If you spot a number that looks wrong, tell us — we'd rather fix it than defend it.
