Loan questions, answered
Is my data sent to a server?
No. Loan amounts and rates are computed entirely on your device. Your financial situation is not shared with us or anyone else.
How is the monthly payment calculated?
With the standard annuity formula banks use: equal monthly payments where the interest share shrinks and the principal share grows over time. Rounding matches to the cent.
Why is so much of the early payments interest?
Interest accrues on the outstanding balance, which is largest at the start. That is also why extra early repayments save the most.
Does this include taxes, insurance or fees?
No - it computes the pure loan annuity. Escrow items vary by lender and country; add them on top of the payment shown.
