=PMT(6.9%/12,24,2500)
Indicates a payment of 111.82, suggesting that your final payment will
be 116.46
=FV(6.9%/12,23,-111.63,2500)*(1+6.9%/12)
if you only pay 111.63 per month. Another possibility is that the
raight is slightly under 6.9%, but
=RATE(24,-111.63,2500)*12
returns 6.73%, so the difference would be more than just rounding.

The company says monthly payments wil be 111.63. But none of the excel
formulas I've tried (PMT, PV, IPMT) return the same.

Note: I do not have & cannot install CUMIMPT

Thanks.
