Step by step
- 1Column A = Annual Interest Rate, Column B = Total Loan Term (months), Column C = Payments Made So Far, Column D = Monthly Payment (as a negative number).
- 2In E2 enter =PV(A2/12,B2-C2,D2) — this returns a negative number; wrap with ABS or negate: =-PV(A2/12,B2-C2,D2).
- 3Alternatively use =CUMPRINC(A2/12,B2,LoanAmount,1,C2,0) to sum only the principal paid and subtract from original loan.
- 4Verify: PPMT and IPMT functions can confirm the split at any payment number.
Tips
- If your payment is stored as a positive number, add a minus sign in the formula: =-PV(A2/12,B2-C2,-D2) or ABS(PV(...)).

Frequently asked
What is the difference between PV and CUMPRINC approaches?
PV calculates the remaining balance as the present value of future payments — simpler but requires knowing the payment amount. CUMPRINC sums the principal repaid and subtracts from the original principal — useful when you know the loan details directly.
How do I find the monthly payment if I only know the loan details?
Use PMT: =PMT(AnnualRate/12,TermMonths,-LoanAmount) which returns the regular payment amount.
