Supports two common mortgage repayment methods for apples-to-apples comparison under different amortization logic.
Switch strategies to compare remaining term, monthly payment, and total interest in one view for better decision-making.
All mortgage parameters are processed in-browser and never sent to servers.
Before making a lump-sum payment, enter current loan parameters and compare "shorten term" vs "reduce monthly payment" side by side.
Run the same mortgage under amortized and equal-principal modes to see differences in total interest and remaining term.
Use the reduced-payment mode to estimate monthly cash-flow relief and decide how much liquidity to keep for household expenses.
Estimate interest savings from prepayment first, then compare against refinance costs to support a data-driven loan optimization decision.
Pick either "From Original Loan" or "From Current Balance", then enter loan amount/term/months paid or remaining balance/remaining months/current rate.
Enter your prepayment amount, choose amortized or equal-principal repayment, and select either "Shorten Term (Same Payment)" or "Reduce Payment (Same Term)".
Review before/after monthly payment, remaining months, and total interest. Focus on "Interest Saved" to decide which strategy fits your cash-flow goal.
