Solve one unknown value at a time: monthly payment, loan amount, or payoff term. Perfect for installment loan planning and budget checks.
For fixed-rate installment loans, monthly payment is computed as:
Where P is principal, r is monthly interest rate, and n is total number of monthly payments.
Yes. Switch the mode to solve either monthly payment, principal, or term. The selected mode disables its corresponding input and computes it from the other values.
This model assumes a fixed interest rate over the full loan term. Variable-rate loans need periodic recalculation as rates change.
No. It calculates principal and interest only. Use mortgage-specific calculators for escrow, taxes, insurance, and PMI.
