It is built from a few inputs and a simple chain of math: - **LTV** = current loan balance / original home value (no appreciation assumed in v1). - **Amortize month by month** until the balance reaches 80% of the original value (request-cancel) and 78% (auto-terminate). - **Total PMI paid** = monthly PMI charged across every month until the loan reaches 80% LTV. - **Extra-payment accelerator** re-runs the schedule with extra principal to show how many months and how much PMI you save. - **Extra needed** solves for the extra monthly amount that reaches 80% LTV in a target window, such as 12 or 24 months. Estimates only. LTV is based on the original purchase price or appraised value, not estimated appreciation, and actual removal depends on taxes, appraisal rules, and lender policy. FHA MIP, VA loans, and reappraisal-based removal differ and are out of scope.

You can also request cancellation earlier, at 80% LTV. RateAPI projects both dates from your home price, down payment, rate, and term, so you know exactly which month PMI is requestable and which month it auto-terminates. When does PMI drop off? At 80% loan-to-value you may request PMI cancellation; the lender is not required to remove it automatically at that point. At 78% LTV the lender must auto-terminate PMI based on the original amortization schedule, provided you are current on payments. RateAPI returns the month and date for both thresholds so you can plan to request cancellation early rather than wait for auto-termination. What is the difference between 78% and 80% LTV? The estimator amortizes your loan month by month: each month interest equals the balance times the monthly rate, principal is the payment minus interest, and the balance falls. LTV is the balance divided by the original home value. RateAPI records the first month the balance hits 80% of the original value (request-cancel) and 78% (auto-terminate), and sums the monthly PMI charged until 80% to get total PMI paid. How is the PMI-removal date computed? Yes. Paying extra principal each month lowers your balance faster, so you reach 80% LTV sooner. RateAPI re-runs the amortization with your extra monthly payment and reports how many months earlier PMI drops and how much PMI you save. It also solves for the extra monthly amount needed to reach 80% LTV in a target window, such as 12 or 24 months. Can I remove PMI faster? Yes. If you do not supply a rate, the estimator resolves the current best market mortgage rate for your state using ranked credit union rates from RateAPI /v1/decisions, then amortizes the loan at that rate. You see results driven by real lender rates, not a generic national average. Does this use real lender rates? Yes. RateAPI offers a free tier with 20 requests per month.
